1 Preface
1.1 General System Description
The Electronic Test System (ETS) is an easy to use electronic test system that provides the user with comprehensive objective information on the physical variables of a steam sterilizer.
In addition to providing an alternative to the Bowie and Dick test, a number of other important functions and tests can be performed by the device.
Its performance is highly reproducible and equivalent in terms of the performance of a standard Bowie and Dick test pack as described in EN 285 and EN ISO 11140-3. It is tested in accordance with the methods described in EN ISO 11140-4.
It therefore satisfies the requirements for a daily steam penetration test as prescribed in EN ISO 17665-1.
An "Early Warning" indication is given to further qualify the pass result of a Bowie and Dick test cycle.
A "Fail" result is indicated if there is sufficient residual air within the chamber to create a Bowie and Dick test failure as described in EN 285. A "Fail" result will also be indicated if the fundamental sterilization parameters defined in EN 285 and by the WHO (134°C / 3 min) are not met.
The main component is the ETS Sensing Unit which functions as a stand-alone measurement system, providing clear "Pass" or "Fail" results and, if applicable, the "Early Warning" indication.
The system can be further enhanced by using the optional ETS USB Data Reader. The ETS USB Data Reader enables data transfer from the ETS Sensing Unit to a computer.
In combination with the optional ETS PC Software 4110, additional information on the sterilizer's performance can be obtained, such as the Leak Rate Test (EN 285), Dilution factor, F
0
Integration and Sterilization Parameter Indication (according to EN 285 and WHO 134°C for 3 min). The software also offers diagnostic functions such as a cycle comparison. This important function helps to identify process variations and supports finding causes of failure(s) and recommendations for possible remedial action.
Additionally, the ETS PC Software 4110 provides a secure and easy to use digital archive in which all relevant information is stored required for full trace ability.
_
Note: To facilitate the installation process for the entire system it is recommended to
install and start the ETS PC Software 4110 first. The installation (connection) of the ETS USB Data Reader shall be the second step.
This procedure provides also the benefit of access to the full documentation
available in the on-line help of the software package. The ETS Sensing Unit requires no installation.
1.1.1 Intended Use
The primary function of the ETS Sensing Unit is to monitor the air removal stage and the sterilization phase of a steam sterilization cycle as required by EN ISO 17665-1.
The ETS Sensing Unit can be used as alternative to the Bowie and Dick test as described in EN 285. Furthermore, data logged by the ETS Sensing Unit can be used for calculation of a Leak Rate in accordance to EN 285.
The ETS Sensing Unit can also be set in Data Logging Mode for use in steam sterilization cycles operating at temperatures other than 134°C for 3 minutes. When used in this mode the software allows individual interpretation of sampled data. No Bowie and Dick result will be available then.
_The ETS Sensing Unit offers the following functions and features:
• Daily steam penetration test (Bowie and Dick test)
• Early Warning (as part of steam penetration test result)

2.3 Instructions for Use
2.3.1 Identification System
You may want to dedicate an ETS Sensing Unit to a specific sterilizer. A tag can be attached to one of the handle bars or the upper ring of the ETS Sensing Unit. The adherance of labels to the silicon material of the ETS Sensing Unit may be poor. This may cause loss of identification.
2.3.2 Operation
2.3.2.1 Bowie and Dick Test Mode
• The Bowie and Dick Test Mode is activated by pulling the switch on top of the ETS Sensing Unit once in the indicated direction (Figure 2). Ensure that the switch returns to its original position. The status of the unit is shown.
_Figure 2: Actuation of the ETS Sensing Unit switch
• _Check status before use. See Section 5 LED Guides on Page 19.
• When a single flashing yellow LED is shown place the ETS Sensing Unit in
the centre of the steam sterilizer at a height of about 10 cm above the base.
• Start the Bowie and Dick test cycle on your sterilizer. Ensure that the cycle starts within 5 minutes after switching on the ETS Sensing Unit otherwise it will switch off automatically to save energy.
• After the Bowie and Dick test cycle is completed remove the ETS Sensing Unit from the sterilizer, holding it by the handles.
Caution: Wear protective gloves, as the ETS Sensing Unit will still be hot.
• Check the LEDs on top of the ETS Sensing Unit: if a single yellow flashing LED (Figure 3 - #3) is seen, the unit is still logging. Pull the switch (Figure 2) to stop the unit. All LED's shall be off. Wait 15 seconds for the unit to calculate the result and pull the switch once again to see the result. If no LED is on or flashing after removal from the sterilizer, pull the switch once. If no immediate result indication occurs, wait 15 seconds and pull switch again.
The result is shown and held for 30 seconds. See Section 5 LED Guides on
Page 19.
Note: Allow the ETS Sensing Unit to cool down at room conditions for
at least 2 hours (preferably longer) before re-use in a Bowie and Dick test cycle. The ETS Sensing Unit will indicate if the temperature is low enough when the black switch is pulled. See

See also Section 6.5.2 Test information on Page 34.
7.8.4 Trace ability, Authenticity and Data Integrity
_
The measurement data as captured by the ETS Sensing Unit can not be accessed in any other way than by transfering the data to a PC using the ETS USB Data Reader and the ETS PC Software 4110. The data stored in the ETS Sensing Unit can therefore not be manipulated.
The transferred data must be identified in a unique manner by completing the window which opens after successful data transfer. Saving the data set to the PC is only possible when all mandatory entries are made.
In case of unsuccessful data transfer the data is NOT lost. It is still available in the ETS Sensing Unit for as long as it is not re-used for a subsequent test. It is therefore important that each time before an ETS Sensing Unit is used for a test, it is verified that the data set is transferred. See Section 5.3 Status on Page 21.
The data stored on a computer is encrypted. Delibarate manipulation of the file will render it useless.
Note: To achieve a secure level of data security a data back-up procedure shall be
established. This is the responsibility of the individual organization.
8 Data Analysis
8.1 Master Overlay (Tab "Master")
_
The Master Overlay function provides a quick comparison between an active record and the master record for the sterilizer in which the test was performed. Based on the mandatory entry of the sterilizer name in the data transfer process the software identifies automatically the matching master record.
8.1.1 Typical Procedure
_
• Open a data record (from logbook or data transfer).
• Display the graph.
• Click the Master tab.
The master record is opened automatically. The graph opens. The graph contains two X­axis.
• Move the active record left or right to synchronize the pressure profile to the desired
control point. See Section 6.5.1.1.7 Moving the Graph on Page 34. The table displayed on the Master tab shows the values (time, pressure, temperatures) at
the control points for both records.
_
Note: The zoom factors for both records shall be the same for meaningful visual
comparison.
8.1.2 Designating a Data Record as Master Record
_
To designate a record as master record:
• Open the record.
• Click Options - Master - Designate as master record.
• Click Yes to confirm the decision.
The name of the master record for the actual sterilizer will appear in Preferences ­Sterilizer. See Section 9.2.8 Sterilizers on Page 66.
Note: There can only be one master record per sterilizer. Each subsequent record
that is promoted to master record will replace the previous master record. The replaced records are not deleted.
8.2 Control Points (Tab "Control Points")
_
The control points indicate the time and pressure level during the pre-vacuum stage at which the "pressure change direction" of the sterilization cycle changes.
A pressure control points is identified:
• when a vacuum valve is opened (1, 9)
• when a steam valve is opened and vacuum valve is closed (3, 5, 7)
• when a vacuum valve is opened and a steam valve is closed (2, 4, 6)
• when a steam valve is opened (1)
• when the valve for sterile air admission is opened (11)
The pressure control points list is extended with points of interest showing the time and pressure:
• at first measured value after achieving 134.00°C (8)
• at last measured value still above 134.00°C (10)
• when the end of the cycle is reached (12)
The control point list can display more data. This depends on the selected functions to display in the graph. See Section 6.5.1.1.2 Showing and Hiding Curves on Page 31.
For pressure profiles that contain multiple small pulses or pressure control noise a dampening filter is available to define the sensitivity for the designation of control points. See Section 9.2.9
Preset Values on Page 66 - Pressure Control Points.
8.2.1 Condensed List with Control Points
The control points are displayed in a table on theControl Points Tab. Each line in the table contains measured and calculated data related to the control point.
The condensed list with control points can be exported for further analysis. See Section
7.7.2 Exporting the Control Points on Page 43.
8.2.2 Control Points in Table
The full data table is displayed on theTable Tab. The row that represents a control point is indicated by a chronological numeric label in the column Control Point. The row is also high-lighted.
8.2.3 Differences between ETS and Sterilizer
Due to the wide variation in sterilizers and sterilization programs and the dynamic nature of the sterilization process the control points determined by the ETS can deviate from those indicated on your sterilizer documentation.
Fast pressure changes in combination with a 1-per-second measurement interval and pressure sensor inaccuracy are the main reason for this.
It can also happen that the ETS software detects more or less control points. This is caused by the nature of the pressure control of your sterilizer. "Noise" on the pressure curve can be interpreted as real control points. They might, however, be only the result of rapidly opening and closing steam and/or vacuum valves in order to force a controlled pressure increase or decrease.
8.2.3.1 Setting a Filter for Control Point Recognition
_
The ETS software algorithm can be fine-tuned to match the sterilizer documentation.
Analysis of a large number of pressure control curve show that a vast majority is correctly interpreted by the algorithm using the default settings.
The default values for the filter are:
• Absolute threshold for recognition: 256mbar
• Relative threshold for recognition: 20%
Changing these values increases or decreases the sensitivity of the algorithm to detect control points.
8.3 Table (Tab "Table")
The tab "Table" contains multiple columns with data. The table contents represent measurement data and / or calculated data. Each line in the table shows data that belongs to a single measurement. The sampling rate is fixed at one measurement per second. The number of lines in the table therefore represents the duration of the entire measurement in seconds
The complete table can be exported for further analysis. See Section 7.7.3 Exporting Data
Records to Files on Page 43.
8.3.1 Add or Remove Columns
Table columns that shall display calculated data by default can be preset in Preferences
- Diagnostics. See Section 9.2.2 Showing and Hiding Diagnostic Data on Page 64.
Measurement data is always automatically displayed. Preset columns can be blended out by using unchecking the functions in the window
Functions Calculation data that is not selected to be shown by default can be added by checking the
functions in the Functionswindow
8.4 EN 285 Leak Rate Test (Tab "Leak Rate")
8.4.1 Definition of the Test
The Leak Rate test is used to demonstrate that the quantity of air leakage into the sterilizer chamber during the periods of vacuum does not exceed a level that will inhibit the penetration of steam into the sterilizer load and will not be a potential cause of recontamination of the sterilizer load during drying. The test complies with the Air leakage test described in EN 285.
_
_
• P1 represents the minimum pressure value required to comply to the standard (70mbar). This is also the start of the equilibrium period.
• P2 is the first pressure measurement after the equilibration period has ended.
• P3 is the pressure measurement after 600 seconds.
• The leak rate is calculated as: (P3-P2) / 10 mbar/min
8.4.2 Typical Procedure
_
• Activate the ETS Sensing Unit.
• Place an ETS Sensing Unit in an empty sterilizer cycle.
• Activate the sterilizer's "EN 285 leak rate" test program.
• Remove the ETS Sensing Unit from the sterilizer after completion of the test
program.
• Transfer the data to the PC.
• Open the data record and display the graph.
• Click on the Leak Rate tab to open display the leak rate test information.
• The software will automatically look whether or not the data record contains a portion
that meets the test criteria.
• The result of the test is displayed graphically (bar in graph) and numerically (values in Leak Rate table).
8.4.3 Leak Rate Test Pass and Fail Critera
_
• A portion of in the data record is found that meets the test requirements of EN 285. When the actual leak rate is equal or smaller then 1.3 mbar/min the bar in the graph is displayed Green indicating a "pass" Leak Rate field in the table on the Leak Rate tab indicates the actual leak rate value.
_
_
• A portion of in the data record is found that meets the test requirements of EN 285. When the actual leak rate exceeds 1.3 mbar/min the bar in the graph is displayed Red indicating a "fail" Leak Rate field in the table on the Leak Rate tab indicates the actual leak rate value.
_
_
• No portion of in the entire data record could be found that meets the test requirements of EN 285. The bar in the graph is displayed grey. Leak Rate field in the table on the Leak Rate tab is empty (no result).
_
_
__
• If there exist more potions in the data record that meet the test requirements of EN 285 the highest value for the leak rate will be calculated and displayed graphically and numerically.
8.4.4 Changing the Leak Rate Test Criteria
To change the portion of the data record from which the leak rate is calculated you can change the time at which the start and end measurement of the pressure is taken. The measurement interval is fixed at 600 seconds.
_
Method 1:
• position the cursor over the coloured bar in the graph.
• The cursor changes to a finger-pointing hand
• Hold down the left mouse key and drag the coloured bar to in the desired direction (left
or right)
All leak rate information is instantly updated as you move the bar
• Release the left mouse key to freeze the results of the modification
_
Method 2:
• In the table on the Leak Rate tab double click on the value for First measurement in column t[s]
• Enter a new time
• Confirm with [Enter]
The value for the second measurement is automatically updated (first measurement + 600s)
The leak rate is instantly recalculated The bar moves to the new position.
8.4.5 Storing the EN 285 Leak Rate Test
Document the result of the leak rate test by clicking the Save Leak Rate Result button. The value will be attached to the original data record. The leak rate value is displayed in
the LRT column in the Files window and in the Logbook. It is possible to perform a new leak rate calculation on a data record that already has a
leak rate value attached to it. The original leak rate result however, can not be overwritten.
Note: If required you can add the results of the new calculation manually as a
comment in the Test Informationwindow
8.5 Pressure Change Rate (Tab "Pressure Change")
8.5.1 Definition of the Test
The pressure change rate test is a tool that can be used to determine the rate at which the pressure of a pulse changes.
The result is only meaning full when the entire measurement interval of interest is between two successive control points.
• The measurement interval bar is grey when it includes one or more control points.
• The measurement interval bar is blue when it includes no control points.
_
• The same applies to evacuation pulses.
8.5.2 Typical Procedure
• Open the data record and display the graph.
• Use the zoom function to display the area of interest (optional).
• Click on the Pressure Change tab to display the information.
A coloured bar appears in the graph from 40% to 60% of the visible time range. The rate at which the pressure of a pulse changes can be measured and calculated in the
following manners:
Method 1:
• Enter a time for First measurement in column t[s].
• Confirm with [Enter].
• Enter a time for Second measurement in column t[s].
• Confirm with [Enter].
The pressure change rate is instantly calculated. The coloured bar in the graph indicates the measurement interval. Values for first and/or second measurement can be changed as required.
Method 2:
• Position the cursor over the border of the coloured bar so that the cursor changes to a double-sided arrow
• Hold down the left mouse key and move the cursor to the left or right.
The coloured bar in the graph changes width thus indicating the measurement interval. All information in the table is instantly updated while moving the cursor
• Release the left mouse key to fix the measurement.
Values for first and/or second measurement can be changed as required using method 1.
Alternatively:
• repositioning the cursor on the right or left border of the coloured bar until it changes to a double-sided arrow .
• Hold down the left mouse key and move the cursor to the right or left.
• Release the left mouse key to fix the measurement.
To change the position of the measurement interval leaving the interval itself unchanged:
• position the cursor over the coloured bar
• The cursor changes to a finger pointing hand
• Move the entire bar to the left or the right
• Release the left mouse key to fix the measurement.
8.6 Dilution
The theoretical dilution factor is a dimensionless numerical value. It it represents the dilution based on the pressure control points detected during the portion of the cycle preceding the start of the sterilization period.
The formula used to calculate the theoretical dilution factor is:
P2/P1 x P4/P3 x P6/P5 x ...... x Pn/Pn-1
8.6.1 Overall Dilution Factor
The Dilution factor presented as a single value (Info tab and Sterilization tab) indicates the dilution reached at the start of the sterilization phase.
8.6.2 Continuous Dilution Factor
The Dilution presented as a curve or table represents the actual dilution reached at the indicated time.
8.7 Residual Air
The dilution factor is used to calculate thetheoretical amount of residual air in the chamber. The chamber volume of the related sterilizer under test is derived from the entry made in the Sterilizer Name field when the data is transferred from the ETS Sensing Unit to the computer.
The calculation does not consider quantities of air coming from air leakage or poor steam quality (NCG)
8.7.1 Residual Air as Single Value
The Residual Air presented as a single value (Info tab and Sterilization tab) indicates the amount of air present in the sterilizer at the start of the sterilization phase.
8.7.2 Residual Air as Curve or Table
The Residual Air presented as a curve or table represents the actual (theoretical) amount of air present in the chamber at the indicated time.
8.8 F0 Lethality
A technique commonly applied to steam sterilization is to integrate the lethality of the process using the familiar F0 function. This process involves measuring the temperature within the sterilizer and fitting this data into the F0 equation.
F0 is the integrated lethality function (the equivalent time of exposure at a specified reference temperature, which for F0 is 121°C but could also be 134 °C.
Thus, for a sterilization cycle operating at 134°C for 3 minutes the Fo value would be approximately 60. In other words, exposure at 134°C for 3 minutes is equivalent to an exposure at 121°C for 60 minutes in terms of the microbial lethality of the process.
8.8.1 Formula
The formula used to calculate the F0:
F
0
= 10
(T-121/z)
dt
Where:
• F0 is the equivalent heating time at 121°C, thus 1 F0 unit is equal to 1 minute at 121°C.
• T is the temperature at time interval dt (typical 1 second or 0.0166 of a minute).
• z is the z value of the microbial population for which the lethality is being calculated
(normally 10)

8.11 Theoretical Temperature
The theoretical temperature is calculated from the pressure measured by the ETS pressure sensor.
Calculated results are conforming the steam table. Both the pressure sensors and the temperature sensor for the chamber temperature have a
defined measurement accuracy. See Section 2.2 Technical Data on Page 11. Taking this accuracy into account the theoretical temperature curve can be used to compare the actual chamber temperature with the theoretical temperature that should be obtained when the pressure results from 100% dry saturated steam.
The function can be displayed by default (See Section 9.2.2 Showing and Hiding Diagnostic
Data on Page 64) or shown / hidden on demand (See Section 6.5.1.1.2 Showing and Hiding Curves on Page 31)
8.12 Vacuum Pump Efficiency
The vacuum pump efficiency provides information on the capacity of the vacuum pump to reduce the pressure.
During a steam admission pulse the vacuum pump efficiency is 0. The value displayed indicates the pressure reduction in relation to the previous pressure
measurement. The calculation of each value is performed on two consecutive pressure measurements (1
second interval).
_
_
The formula for calculating the vacuum pump efficiency is:
