ISTA 3A?, in the OPTIONAL Vibration Under Low Pressure, how can do that?
I need a special Pressure Chamber, for simulate that optional Test protocol?
For this optional test sequence you will need a low pressure chamber that can be placed on the vibration table platform and sealed.
The low pressure chamber needs to be in compliance with the apparatus section of ISO 2873 or ASTM D 6653; able to fit on the vibration table; able to draw down the internal absolute pressure to 60 kPa (8.7 psi) for the truck and air test, or 70 kPa (10 psi) for the truck-only test; and able to withstand the air and/or truck random vibration input.
