6.2.4.2.1 Hot water bath test

Initial pressure test date and witness identification

This pressure should be lower than the test pressure of the tank involved.

When performing the constant pressure test, variations in atmospheric pressure shall be taken into account.

This is the lowest level that can be measured in laboratory tests.

The temperature and pressure in the test vessel are recorded during the entire experiment.

The tank shall not be pressurized during the test.

for tanks not more than test pressure of the tank (according to 4.2.1.13.4 tank shall be designed for a test pressure of at least 0.4 MPa),

Japan has been developing the Japanese Experiment Module (JEM), consisting of a multipurpose pressurized laboratory element, an unpressurized exposed facility, a remote manipulator system, and experiments logistics modules.

Frangible discs shall rupture at nominal pressure equal to the test pressure of the shell.

In no case shall the test pressure be less than 300 kPa (3 bar) gauge pressure.

They shall be subjected to an initial test and periodic tests every 10 years at a pressure of not less than 1MPa (10 bar) (gauge pressure).

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

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

6.2.4.2.2.2 Pressure and leak testing of aerosol dispensers before filling

6.6.2.19.4 The 5 year periodic inspection and test shall include an internal and external examination and, as a general rule, a hydraulic pressure test.

6.6.3.15.4 The 5 year periodic inspection and test shall include an internal and external examination and, as a general rule, a hydraulic pressure test.

The MEGC shall not be pressurized during the test.

They shall be made of steel and shall be subjected to an initial test and periodic tests every 10 years at a pressure of not less than 1MPa (10 bar, gauge pressure).

They shall be made of steel and subjected to an initial test and periodic tests every 10 years at a pressure of not less than 0.6MPa (6 bar, gauge pressure).

When the shell and its fittings have been pressure tested separately, they shall be subjected together after assembly to a leakproofness test.

When the shell and equipment have been pressure tested separately, they shall be subjected together after assembly to a leakproofness test.

When no spring loaded pressure relief device is used, the frangible disc shall be set to rupture at a nominal pressure equal to the test pressure.

Each filled aerosol dispenser shall be subjected to a test performed in a hot water bath or an approved water bath alternative.

6.5.4.4.2 Every metal, rigid plastics and composite IBC for liquids, or for solids which are filled or discharged under pressure, shall undergo a suitable leakproofness test and be capable of meeting the test level indicated in 6.5.6.7.3

The JEM manipulator will be used to exchange experimental equipment or samples between the exposed section of the experiment logistics module and, through the airlock, the pressurized module.

For safety, it is recommended to provide the test vessel with an extra bursting disk (bursting pressure approximately 80 of the design pressure of the 10 l test vessel) with a large opening for additional emergency venting of the test vessel in the event that the chosen orifice diameter is too small.

4.1.3.6.3 Unless otherwise indicated, pressure receptacles having a minimum test pressure of 0.6 MPa shall be used.

(b) An equivalent level of safety is achieved by the manufacturer's use of alternative methods for leak detection and pressure resistance, such as helium detection and water bathing a statistical sample of at least 1 in 2000 from each production batch.

The more critical effect of pressurization of vessels has been confirmed by the test results.

For liquids if the test is performed with water

6.6.2.3.2 Shells shall be designed and constructed to withstand a hydraulic test pressure not less than 1.5 times the design pressure.

The Forum subsequently welcomed the overwhelming adoption of the Comprehensive Nuclear Test Ban Treaty in 1996 as an important step in prohibiting nuclear test explosions.

(a) a constant pressure test (for example at atmospheric pressure) when the loss of refrigerated liquefied gas is measured over a period of time or

It consists of a pressurized section and an exposed section.
