1.1 This standard ( Part XII ) covers filling, inspection, testing, mainte-nance and use of portable steel cylinders for the storage and transporta-tion of gases for medical use in cylinders exceeding 500 ml water capacity. The following gases have been covered:
Carbon dioxide, cyclopropane, ethylene, helium, nitrogen nitrous oxide, oxygen and gas mixtures.
1.1.1 Separate codes of practice for some of the gases used in medical cylinders have been already published. The following three codes are relevant:
IS : 8198 ( Part I )-1976〓,
IS : 8198 ( Part III )-1976〓, and
IS : 8198 ( Part VIII)-1976§.
The present code, therefore, covers only those aspects of medical cylinders which have not been touched in the above codes. Thus, inspection during manufacture, usage, periodic testing, disposal of condemned cylinders, filling, marking, labelling, bringing the cylinders in service, transportation and records have not been covered in this code.
