1 Scope

China's national regulation for filling cylinder bundles. It specifies the basic principles and safety requirements, and it applies to bundles with a total water capacity of not more than 3000 litres, holding compressed gas, high pressure liquefied gas and dissolved gas, used at ambient temperatures from minus 40 to 60 degrees C. A cylinder bundle is a frame holding a dozen or so cylinders manifolded together and handled as one unit by crane or forklift. It exists because a user consuming gas steadily does not want to change single cylinders several times a day, and because a bundle is safer to move mechanically than loose cylinders are to move by hand. What it changes for the filler is that the cylinders are no longer filled individually: gas enters through a common manifold, and a fault in one cylinder or one valve is not isolated from the rest. The regulation therefore concentrates on the manifold, the isolation of individual cylinders, and the checks that must be made before a bundle is treated as a single vessel.

This standard specifies the basic principles and safety requirements of cylinder cluster device filling. This standard applies to the use of ambient temperature is -40 °C ~ 60 °C, the total water volume is less than or equal to 3000L, the medium is compressed gas, high Filling liquefied gas and gas cylinder bundling device (gas-gas mixture). This standard does not apply to the medium is liquid - liquid gas mixture, the toxic degree of toxic or toxic gas cluster device filling, it does not apply In the filling of high-pressure liquefied gas (flammable), fixed in the car using the cluster device filling.
