4.5 Procedure of a tightness test
A test may consist of several tests
If a test is performed with multiple tests, the following procedure is
repeated.
Determining the initial value
After starting the test, the sensor head is moved into position and the
starting value of the deformation is set to zero.
Build up pressure and record the deformation behaviour of
the watch housing
The test pressure is built up in the test chamber. In order to compensate
for pressure losses caused by the heating of the air, the test pressure is
continuously regulated during the measurement.
30 / 96 17.10.2019
Page 31
Deformation Deformation
Test pressure Test pressure
Linear deformation behaviour Non-linear deformation
behaviour
The deformation behaviour of the watch is continuously recorded
during pressure build-up and automatically included in the evaluation
algorithm.
Automatic measuring time
The ProofMaster has a new evaluation algorithm which detects elastic
deformation of watches and automatically compensates them.
In the standard setting, the ProofMaster automatically determines the
required measuring time for each measurement. The software continues
the measurement until a meaningful result is obtained.
The measurement time for a simple OK/not OK statement is shorter
than the output of a precise leak rate. It should also be noted that
smaller limits lead to longer measurement times. The maximum time per
test pressure is limited to 300 seconds with automatic measuring time.
For best results in terms of precision and test duration, we recommend
the use of the automatic measurement time.
Description
4.6 Definitions
Deformation measurement
17.10.2019 31 / 96
The measuring method of the ProofMaster is based on the principle of
deformation. The watch is subjected to positive pressure to compress
the watch housing, or a vacuum to expand it. The faster the
deformation is compensated, the larger the leak in the watch case. The
deformation of the case within a certain time serves as the basis for the
measurement to determine whether the watch is leakproof or not.
Leak-tight watch
Under constant pressure, the deformation of the watch housing remains
constant.
Leaky watch
Under constant pressure, the deformation of the watch housing is
reduced.
The difference between the pressure in the test chamber and the
pressure in the watch housing is being compensated at a rate which is
above the limits of the leak rate.
Page 32
Description
Limit
The limit is the maximum permissible leak rate. If the leak rate exceeds
the predefined limit, the watch being tested is classified as non-leaktight.
Relative to the diameter of the watch housing, the following standard
values apply:
Diameter of the watch glass Volume Limit
Ø
<20mm 1000mm
Glass
20mm<Ø
<40mm 2100mm
Glass
40mm<Ø
Glass
Info
The lower the leak tightness limit, the longer the
measurement takes.
This must to be taken into account when planning production.
Leak rate
The ISO 2281 standard specifies the leak rate in µg/min and defines
50µg/min as the limit value for leak tightness at a test pressure of 2
bar. The ProofMaster is configured by default according to these
standard specifications.
To calculate the leak rate, the measuring algorithm needs the exact air
volume in the watch case. The watch sizes suggested in the measuring
program are suitable for a qualitative consideration – we recommend
determining the inner volume of the watch beforehand.
4.7 Reference to standard ISO22810
Leak-tight watch in accordance with standardISO 22810
Relationship between
volume and deformation
Interpretation of ISO 22810
Standard ISO 22810 defines that a watch shall be classified as leaktight if less than 50 µg of air penetrates the watch per minute at a test
pressure of 2 bar.
The ISO 22810 standard does not take into account the volume of the
watch. This means that the leak rate of 50 µg per minute applies to all
watches, regardless of their size.
When testing according to the principle of deformation, the reduction
depends on the free volume in the watch. In a watch with a small
volume, the reduction in deformation is more pronounced with the same
amount of penetrating air. The free volume must be programmed in the
watch for a standard-compliant test.
The standard is based on a pressure of 2bar or 0.5bar. No limit value is
specified for other pressures. It is therefore assumed that the limit of
50 µg per minute applies for all test pressures.

5.1 Safety during use
Use
Cracked glass
Compressed air
CAUTION
Risk of injury from cracked glass!
The positive pressure can penetrate into leaking watches during the test.
If this is the case, the interior of the watches will be under pressure after
the test. The glass in the watch can then splinter or crack. It can cause
serious eye injuries and even blindness.
Mandatory
Observe the instructions for wearing safety goggles in this
Operating manual!
If it is necessary to wear safety glasses, make sure that other people in
the room are at an appropriate distance from the device.
The compressed air devices can be dangerous if they are disconnected
when compressed air is present. A pressurised line that is disconnected
can cause the air to escape extremely quickly as a result of the escaping
pressure, thus posing a danger, especially to the eyes and face.
CAUTION
Risk of injury from compressed air!
If compressed air escapes uncontrolled, there is a risk of injury.
• Take care when working on the compressor or the compressed air
hoses.
Prohibition
Do not exceed the maximum supply pressure of 12bar!
Device components could otherwise burst.
Prohibition
Never force the device cover to open when the device is
under pressure!
Otherwise parts could be ejected.
Mandatory
Follow the obligations set out below:
Check the compressed air hose before each use!
The integrity of the hose is crucial for safety.
Make sure that the compressed air hose is not subjected to any
external mechanical loads!
The compressed air hose must therefore not come into contact with
sources of heat, oils or greases, and must not be crushed, kinked,
pinched or subjected to excessive tensile loads.
Before the unit is put out of operation, the compressed air supply
must be completely disconnected!
To reduce the risk of damage from residual pressure in the unit.

Locating the leak
52 / 96 17.10.2019
Caution - material
Damage to the watch being tested due to water ingress!
The watch will only remain sealed in the water as long as there is a
positive pressure in the housing, and, if the leak in the watch is too large,
there is a risk of water penetrating the interior of the watch during the
water test.
Page 53
Mandatory
Follow the obligations set out below:
Only perform the water test once the "Leak Finder"program has been
executed and the watch can be submerged in water without any risk!
Perform the test in the water immediately after the "Leak Finder"
program has ended!
The watch can only be safely immersed in water for as long as there is
positive pressure in the housing.
