cylinders for further service, regardless of the method of manufacture of the shell. It does
not exclude the application of additional national requirements.
This Malaysian Standard does not specify the requirements for initial approval and
requalification of the porous mass and of the shell.
This Malaysian Standard does not exempt the filler of an acetylene cylinder from the
obligation to carry out an external visual examination prior to each charging and to ensure
that cylinders are suitable for refilling with acetylene.
Due to the presence of a porous mass in the cylinder, neither a hydraulic pressure test nor
visual inspection of the internal surface of the shell is carried out.
Additional International Standards cover similar requirements for seamless steel,
welded-steel and seamless aluminium cylinders and the inspection and tests to be carried
out during normal filling procedures.
