ISO 3807 pdf download Gas cylinders — Acetylene cylinders — Basic requirements and type testing
This International Standard specifies the basic and type testing requirements for acetylene cylinders withand without fusible plugs with a maximum nominal water capacity of 150 1 and requirements regardingproduction/batch test procedures for manufacturing of acetylene cylinders with porous material.
lt does not include details of the design of the cylinder shell; these are specified, for example, inIS09809-1,1S0 9809-3,IS04706andIS0 7866
NOTEThe limitation to 150 lis derived from the definition for cylinder in the UN Model Regulations. However,in practice acetylene cylinders in general have lower water capacities than 150 l.

3 Terms and definitions
For the purposes ofthis document, the following terms and definitions apply.31acetylene cylinder
cylinder, manufactured and suitable for the transport ofacetylene, containing a porous material (3.6) anasolvent (3.9) (where applicable) for acetylene with a valve and other accessories affixed to the cylinder
Note 1 to entry: For solvent-free acetylene cylinders, see Clause 7.
Note 2 to entry: When there is no risk ofambiguity, the word “cylinder”is used.
non-reclosing pressure relief device designed to function by the yielding or melting ofa plug offusiblematerial at a predetermined temperature
maximum acetylene content
Note 1 to entry: When using tareS, the maximum acetylene charge may be used. The maximum acetylene chargeis the maximum acetylene content minus the saturation acetylene.
Note 1 to entry: The porous material can be either monolithic, consisting ofa solid product typically obtained byreacting materials or by materials connected together with a binder, or non-monolithic, consisting ofgranularfibrousorsimilar materials without addition ofa binder
Note 1 to entry: For the determination ofthe porosity see Annex A or Annex l
Note 1 to entry: The following abbreviations are used: “A” for acetone and “DMF” for dimethylformamide.
