INTRODUCTION

1 Introduction

The dynaROCK II is a portable device for testing the hardness of materials.

The measurement is implemented according to the Leeb hardness testing

method. Using this method, most metallic materials can be measured within a

large measuring range.

For different applications, six impact device types are available. The type of the

connected impact device is identified automatically.

Measurements can be made at any angle, even overhead.

The hardness is displayed directly in the hardness scales HRB, HRC, HV, HB,

HS or tensile strength (MPA; measurable only with the impact device types D,

DC and G). A limit-value acoustic alarm facilitates the evaluation.

The dynaROCK II is provided with a measured value memory in which up to

500,000 measured values, with date, time and measuring parameters, can be

stored. The stored series of measurements with the corresponding statistical

data can be printed or display at all times.

In addition, the dynaROCK II offers the so-called test report printout. Here the

measured values are printed immediately. A statistical evaluation cannot be

printed out with it in this case.

3.1.1 Special impact device types

The technical specifications of the individual impact devices are indicated in

Table 4, the requirements on the sample surface in Table 5 and the diameters

and depths of the arising impressions in Table 6.

10

EQUIPMENT DESCRIPTION AND MEASUREMENT PROCESS

Type D : Standard impact device for most hardness testing tasks

Type DC : Extremely short impact device for measurements at

inaccessible locations or in pipes

Type C : Impact device with lower impact energy e.g. for

measurements on surface-hardened parts. The

impressions are approximately only half as deep as in case of

impact device D, however, the requirements on the surface

quality are higher.

Type D+15: The impact device has a recessed reactance coil and a

smaller placement surface (11 mm x 14 mm instead of  20

mm) for hardness measuring in slots and deepened areas.

Type DL : Impact device with longer impact body. The diameter of the

front pipe is 4.2 mm.

Type G : The impact energy increased with type G for measurements

on heavy casting and forged parts. Measurement only in the

Brinell range up to 650 HB. The requirements on the

surface are not as extensive as with type D.

11

EQUIPMENT DESCRIPTION AND MEASUREMENT PROCESS

3.2 Leeb hardness measurement process

The measurement process employed here exploits the difference between the

impact and rebound speed of a small impact body. This is fired in the impact

device onto the sample surface with an exactly defined energy. The plastic

deformation on generating the impression on the sample surface requires

energy. Therefore the rebound speed of the impact body is lower than the

speed before the impact. Both speeds are measured inductively 1 mm above

the surface.

The hardness number is calculated according to the following formula:

Where:

HL - Leeb hardness

VB – Rebound speed

VA – Impact speed

From the HL values, hardness numbers in the usual hardness scales are

obtained using empirically-determined revaluation tables. These revaluations

are dependent on material.

5 Implementation of a measurement

5.1 Preparation and control-check before the measurement

5.1.1 Preparation of the sample

The preparation of the sample surface should correspond to the relevant

specifications from 5 (on Page 41 in the appendix).

• In case of sample preparation, procedures which can influence the surface

hardness of the sample, such as e.g. overheating, cooling etc., should be

avoided as far as possible.

• If the surface of the sample is too uneven, measuring errors can occur. The

sample surface should shine metallic, be smooth, level and free of dirt and

oil.

• Underlay for test specimens:

– In case of heavy test specimens, no underlay is necessary (see 5

(Page 41 in the appendix): Minimum weight of the sample)

– Test specimens of medium weight require a flat, solid underlay (see

5 (Page 41 in the appendix): Minimum weight of the sample)

16

IMPLEMENTATION OF A MEASUREMENT

– The sample must be placed onto the underlay so that it is stable and

flush

• In case of measurements on large plates, long rods or curved work pieces,

the impact effect of the impact device can cause small deformations or

vibrations which lead to measuring errors, also when the weight of the

sample corresponds to the specifications in 5 (on Page 41in the appendix).

In such cases, the sample should be reinforced or supported on the

opposite side of the measuring point.

• In the ideal case, the sample surface should be level. In case of surfaces

with a radius of curvature R<30 mm (with impact devices of the type D, DC,

D+15, and C) and R<50 mm (with impact devices of the type G), a

correspondingly shaped placement ring, which is adapted to the radius of

curvature, must be screwed onto the impact device for the secure mounting

of the impact device.

• In case of samples with hardened surface, the case hardening depth should

correspond to the specifications in 5 (on Page 41 in the appendix).

• The sample should not indicate any internal magnetism, since this can

influence the measurement of the speeds of the impact body.

IMPLEMENTATION OF A MEASUREMENT

5.1.2 Measuring parameter settings

The required measuring parameters must be set-adjusted according to

requirements. It involves the following:

Material

Hardness scale

Impact direction

Tolerance limits

Online statistics

Test report printout

The measuring parameters are described in Chapter 7.

5.2 Measurement

Before the measurements, the test device should be checked by means of a

hardness comparison block. The precision and repeatability of the

measurements should lie within the limits from 2 (on Page 38 in the appendix).

5.2.1 Operational startup

• Connecting impact device

• Press the red activation key to switch on the device. With the start, the last

set-adjusted measuring parameters are loaded (see Chapter 7). The device

is now ready for measurement.

5.2.2 Preparation of the impact device

Slide the bolt-arming sleeve down slowly and uniformly to the stop. Then slowly

bring the bolt-arming sleeve into the starting position again.

18

Note: The hardness of the comparison block is indicated on the

block. Hardness comparison blocks with DKD certificate are

available in three different hardnesses. When the measured

values of the

dynaROCK II

deviates from the hardness of the

comparison block, the device must be calibrated.

IMPLEMENTATION OF A MEASUREMENT

5.2.3 Mounting the impact device

Press the placement ring of the impact device firmly and without wobbling onto

the test specimen. The impact direction must correspond to the set-adjusted

direction.

5.2.4 Measuring

Press release button above on the impact device. Sample and impact device

must be held steady and stable in this case.

For every measuring point, 5 measurements should be carried out whose

deviation should not exceed ±15 HL .

The minimum distance between two measuring points, and the minimum

distance between a measuring point and the edge of the sample, should

correspond to the specifications in 1.

IMPLEMENTATION OF A MEASUREMENT

The measurement is completed with the acoustic signal.

If the Leeb hardness is to be converted into another hardness scale, a

benchmark comparison test must be carried out in order to obtain a suitable

conversion factor for the corresponding material. Test measurements are

carried out on the same sample with a well calibrated Leeb hardness testing

device, and with another hardness tester, according to the required hardness

scale. For every hardness number, 5 measurements with the Leeb hardness

testing equipment must be carried out, uniformly distributed around a hardness

impression of the other hardness testing device. At least three hardness

impressions should be measured. The average value of the Leeb hardness and

the average value of the measured values in the other hardness scale are used

for the generation of a comparison hardness curve. The comparison hardness

curve should be calculated from at least three series of corresponding values.

6 Operation of the device

6.1 Switching-on

Press the red activation key to switch on the device.

If an impact device is connected, then the type of the impact device is identified

automatically and the device goes into measurement mode. At this point it

should be checked whether the impact device type has been identified

correctly.

6.2 The measurement window

If an impact device is connected, the measurement window is displayed after

switching on.

place, Vickers, Brinell, Shore and tensile strength without any decimal place. If

the measured value lies within the tolerance limits, a beep is emitted, otherwise

2 short tones.

6.2.3 Key layout of the measurement window

6.3 Statistics

If the measured value memory is switched on, the values of a series can be

evaluated statistically at all times. Even if the measured value memory is not

switched on, the hardness numbers are always temporarily stored until the

measurement window is closed. Thus a statistical evaluation of the measured

values can also be displayed with switched off measured value memory.

If the hardness scale or material is changed by key press in the measurement

window, the statistics are reset.

22

DIR Changes the impact direction

SCALE Changes the hardness scale. If the tolerance limits cannot be

converted into the new scale, they are automatically set to 0.
However, the values set-adjusted in the measuring parameters
are stored so that, in case of renewed changeover into a scale
in which the limits can be converted, these are again set to the
adjusted values.
In the system settings it can be determined whether the scale
should be changed automatically or a dialog should be opened
(see 9.4.2).

Deactivated if the measured value memory is switched on.

MAT Changes the material. If the currently selected hardness scale

is not defined for the new material, the hardness scale is
automatically reset to HL.
In the system settings it can be determined whether the
material should be changed automatically or a dialog should be
opened (see 9.4.3).

Deactivated if the measured value memory is switched on.

DEL Deletion of the last measured value

STAT Display of the statistics concerning the already measured

values

OPERATION OF THE DEVICE

6.3.1 Display of the statistics

The output of the statistical evaluation is

implemented as soon as the number of

measurements set-adjusted in the measuring

parameters have been made, or the key STAT is

pressed. First to be outputted are average value,

standard deviation, relative standard deviation

(standard deviation in % of the average value),

minimum, maximum and the number of values. Standard deviation and average

value are outputted with 1 decimal place more than is usual for the hardness

scale. The Rockwell scales are usually indicated with 1 decimal place, Vickers,

Brinell, Shore and tensile strength without any decimal place. The relative

standard deviation is outputted with 2 decimal places.

If the key STAT is pressed again in this view, a window is opened in which are

displayed the measured values with which the statistics were calculated. Here it

is possible to delete obviously incorrect values.

For the deletion of a value, the marker is set with the cursor key to the value to

be deleted and then DEL is pressed.

If the display window is closed with ESC, a request is made as to whether the

changes should be accepted or rejected. If the changes are accepted, the

statistical values will be newly calculated.

The statistics window is closed with ESC.

MEASURING PARAMETER

7 Measuring parameter

7.1 Description

After switching on the dynaROCK II, the last employed combination of

measuring parameters is always active.

The measuring parameters in detail:

Im p ac t di r ec ti on : The impact direction is set-adjusted with the aid of the key

DIR in the measurement window.

Ma t er ia l : The currently selected material.

Ha r dn es s s ca le : The current hardness scale into which the measured

values are converted as appropriate. In the measurement

window the hardness scale can be switched over with the

aid of the key SCALE, unless the test report printout or

the measured value memory are activated.

Ra t in g: Upper and lower limit for the rating GOOD are stored

here. If a measured value lies outside of these limits, an

acoustic signal is triggered with the measurement (2 short

tones). If the measured value lies within the limits, an

individual tone indicates the successful measurement.

If the value 0 is entered for upper and lower limit, no

verification of the measured value is implemented.

The value for the lower limit must of course be smaller

than that of the upper limit.

With active rating, the overshooting or undershooting of

the limits is displayed in the measurement window.

St a ti st ic s : The number of measured values which should be

statistically evaluated without the use of the measured

value memory is defined here. If this number of measured

values is reached, the statistics window is opened

automatically (see 6.3.1).

24

MEASURING PARAMETER

Tes t re po r t p ri n to ut : If a small test report printer is connected, the line-by-

line printing of the measured values here can be switched

on and off.

7.2 Administration of the measuring parameter sets

In the dynaROCK II combinations of measuring parameters can be stored

under a user-defined name. In this way, the measuring parameters required for

specific applications can be called up easily.

7.2.1 Editing measuring parameters

Under the menu item Measuring parameter / Edit, the measuring

parameters can be adjusted.

Only the current measuring parameters can be changed. In order to change a

stored configuration, this must first be loaded and stored again after the change

has been implemented.

7.2.2 Saving measuring parameter

The current measuring parameters can be stored in the menu item Measuring

parameter / Save under a user-defined name.

According to choice of the menu item, a text entry window is opened in which

the new name for the data record can be entered.

25

The following are stored:

 The assigned name

 The material

 The hardness scale

 The upper and lower limit for the rating ´GOOD´

 The test report printout (on or off)

 The number of values which should be used for the statistical

evaluation

MEASURING PARAMETER

7.2.3 Loading measuring parameters

Under the menu item Measuring parameter / Load, the stored measuring

parameters can be called up.

With the cursor keys, the required item is selected from the list of the existing

measuring parameter data records and loaded with ENTER.

7.2.4 Deleting measuring parameters

Under the menu item Measuring parameter / Delete, a stored measuring

parameter data record can be deleted if it is not required any longer.

With the cursor keys, the required item is selected from the list of the existing

measuring parameter data records and deleted with ENTER.

8 Memory functions

In the dynaROCK II, a total of up to approx. 500,000 measured values can be

stored. These measured values are organized in series of measurements

(series).

A name is assigned to every series of measurements, under which they can be

displayed or printed later. The hardness numbers are stored with time, date and

impact direction of the measurement. In addition, the measuring parameters

are stored with which the series was recorded:

 The impact device type

 The material

 The hardness scale

 The upper and lower limit for the rating ´GOOD´

In case of printing or outputting of a series of measurements, average value

and standard deviation are calculated and displayed.

26

If the measured value memory is active, material and hardness scale

cannot be changed any longer in the measurement window by key press!

MEMORY FUNCTIONS

8.1 New Series

In the menu item Memory functions / New series, the name of a new series

of measurements can be stipulated with the text entry function (see 4.4). On

completion of the input, the measurement window is opened and the measured

hardness numbers are stored under this name.

The measuring parameters active before the input of the name for the new

series of measurements are employed. These measuring parameters cannot

be changed as long as the hardness numbers are stored.

The recording of the series of measurements is ended when the measurement

window is closed. The request follows as to whether the hardness numbers

should be finally stored in this series.

8.2 Continue measurement in existing series

Under menu item Memory functions / Continue series of measurements,

a series of measurements can be selected to which the new measured values

are attached. If the series of measurements was begun with an impact device

type other than that currently connected, a continuation of the measurement is

not possible.

8.3 Deleting a series

If series of measurements is no longer required, it can be deleted under menu

item Memory functions / Delete.

8.4 Displaying a series

The content of a series of measurements can be displayed and edited at this

point, together with the statistical information (see 6.3.1).

8.5 Data transfer

The saved series of measurements can be transferred to the PC by means of

the transfer program supplied with the dynaROCK II.

For that, the dynaROCK II has to be connected to the PC via USB. The
