(b) the maximum effective gauge pressure to which the shell is designed, which shall be

These transformers contained PCBs in the form of Askarel ... .

The pressure is recorded by a pressure transducer(s) capable of recording slow and fast (at least 1000 points sec.

This box can be used to change the pressure of the gas.

For example, solid rocket motor casings and solar array cable wraps will stay attached to the spacecraft.

Leakproofness test means a test using gas subjecting the shell and its service equipment to an effective internal pressure of not less than 25 of the MAWP

6.6.3.5.5 In addition to filling, discharge and gas pressure equalizing orifices, shells may have openings in which gauges, thermometers and manometers can be fitted.

Leakproofness test means a test using gas subjecting the shell and its service equipment, to an effective internal pressure not less than 90 of the MAWP

The vacuum relief device shall be set to relieve at a vacuum setting not greater than minus ( ) 0.21 bar unless the shell is designed for a higher external over pressure, in which case the vacuum relief pressure of the device to be fitted shall be not greater than the tank design vacuum pressure.
