4.2.1.13.9 For insulated portable tanks the capacity and setting of emergency relief device(s) shall be determined assuming a loss of insulation from 1 of the surface area.

Test pressure means the maximum gauge pressure at the top of the shell during the hydraulic pressure test equal to not less than 1.5 times the design pressure.

The bursting pressure of the disk fixed to the 10 l vessel should be equal to the maximum rupture pressure of the bursting disks to be fitted to the IBC or tank.

This pressure thing really amazes me that these animals can exist there at a depth with pressure enough to crush the Titanic like an empty Pepsi can.

When the pressure test is a part of the inspection and test, the test pressure shall be the one indicated on the data plate of the portable tank.

They keep it for you know, it's like the old wine bottles, you keep it for decoration or maybe fill it with water again, which proves it's not the water.

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

In the case of multi purpose tanks, the combined delivery capacity of the pressure relief devices shall be taken for the gas which requires the highest delivery capacity of the gases allowed to be transported in portable tanks.

While under pressure, the portable tank shall be inspected for any leaks in the shell, piping or equipment.

4.2.1.13.6 Portable tanks shall be fitted with pressure relief devices and emergency relief devices.

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.

Pressure relief devices shall operate at pressures determined according to both the properties of the organic peroxide and the construction characteristics of the portable tank.
