6.3.3.2 Test method
Figure 6 Special first sub-table for pressure resistance test of aerosol valve fixed cover The unit is millimeter
Measure the h value of the sample with a special dial indicator (see Figure 2) and put it into the pressure tester. Pressurize it to 1.8MPa and keep it for 1min. After unloading, take out the sample and then measure the h value with a special dial indicator. Calculate the change between the two measured values. The change Ah is not greater than 0.30mm for passing the calculation as shown in formula (1):
Ah h hi
Where:
h: ---I value after being subjected to internal pressure, unit: millimeter (mn); hole ---h value before being subjected to internal pressure, unit: millimeter (mm). 6.3.4 Pull-off force test of liquid guide tube
