Use of compressed gases is widespread: in commerce and industry as a fuel, in sports such as diving, and in medical and firefighting equipment. Serious injury can result from the sudden release of the stored energy in a compressed gas cylinder through failure. The risk of failure can be substantially reduced by the maintenance of these cylinders in good repair and by regular inspection and testing.
Gas cylinder test stations require authorisation from WorkSafe New Zealand under the Health and Safety at Work (Hazardous Substances) Regulations. Accreditation by IANZ under the Gas Cylinder Testing Laboratory programme, a specialist sub-set of the IANZ Mechanical Testing Laboratory programme, is the most common route to authorisation by WorkSafe.
A Fee Schedule can be found under the Forms section on this page.
IANZ accreditation of gas cylinder test stations covers hydrostatic testing (stretch and proof), internal and external examination of cylinders, and the mass check, as appropriate for the type of testing being carried out.
