6.6.2.12.2.1 To determine the total required capacity of the relief devices, which shall be regarded as being the sum of the individual capacities of all the contributing devices, the following formula shall be used

6.6.4.7.3 Under the circumstances described in 6.6.4.7.1 and 6.6.4.7.2 together with complete fire engulfment the combined capacity of all pressure relief devices installed shall be sufficient to limit the pressure in the shell to the test pressure.

TP16 The tank shall be fitted with a special device to prevent under pressure and excess pressure during normal transport conditions.

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.

6.6.4.7.1 In the case of the loss of vacuum in a vacuum insulated tank or of loss of 20 of the insulation of a tank insulated with solid materials, the combined capacity of all pressure relief devices installed shall be sufficient so that the pressure (including accumulation) inside the shell does not exceed 120 of the MAWP.

As the activities of armed opposition groups adapt and change in reaction to political and security force pressures, the acquisition and production of quality security information and analysis becomes increasingly important.

4.1.3.6.7 Prior to filling, the filler shall perform an inspection of the pressure receptacle and ensure that the pressure receptacle is authorized for the substances to be transported and that the provisions of these Regulations have been met.

6.2.4.2.2.2 Pressure and leak testing of aerosol dispensers before filling

Holding time means the time that will elapse from the establishment of the initial filling condition until the pressure has risen due to heat influx to the lowest set pressure of the pressure limiting device(s)

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.

4.1.3.6.4 Unless otherwise indicated, pressure receptacles may be provided with an emergency pressure relief device designed to avoid bursting in case of overfill or fire accidents.

4.2.3.6.3 Shells intended for the transport of helium can be filled up to but not above the inlet of the pressure relief device.

6.6.3.8.1.1 To determine the total required capacity of the relief devices, which shall be regarded as being the sum of the individual capacities of the several devices, the following formulae This formula applies only to non refrigerated liquefied gases which have critical temperatures well above the temperature at the accumulating condition.

Service equipment means measuring instruments and filling, discharge, venting, safety, pressurizing, cooling and thermal insulation devices

Vents or pipes from the pressure relief device outlets, when used, shall deliver the relieved vapour or liquid to the atmosphere in conditions of minimum back pressure on the relieving devices.

Pipework to vent the vapour or liquid from the outlet of the pressure relief devices, when used, shall deliver the relieved vapour or liquid to the atmosphere in conditions of minimum back pressure on the relieving device.

The space between the frangible disc and the device shall be provided with a pressure gauge or a suitable tell tale indicator. This arrangement permits the detection of disc rupture, pinholing or leakage which could cause a malfunction of the pressure relief device.

All pressure relief device inlets shall under maximum filling conditions be situated in the vapour space of the shell and the devices shall be so arranged as to ensure the escaping vapour is discharged unrestrictedly.

All pressure relief device inlets shall under maximum filling conditions be situated in the vapour space of the shell and the devices shall be so arranged as to ensure that the escaping vapour is discharged unrestrictedly.

Each pressure receptacle with a wall thickness at any point of less than 2.0 mm and each pressure receptacle that does not have fitted valve protection shall be transported in an outer packaging.

It's a scoop. Produces more pressure up in the engine.

A venting device shall be fitted if dangerous overpressure may develop due to normal decomposition of substances.

6.6.2.8 Pressure relief devices

6.6.4.6 Pressure relief devices

B. Staff stress and security

(a) The pressure and emergency relief devices installed on the IBC are designed to take appropriate account of the self accelerating decomposition of the organic peroxide and of fire engulfment and

(d) the lowest set pressure of the pressure limiting device(s).

Additional surfaces were to be installed at edges of the solar panels in order to make the centre of solar pressure coincide with the centre of mass of the spacecraft.
