Specifies requirements and provides guidance on the operation and maintenance of boilers, pressure vessels, associated control and safety equipment, piping and auxiliaries, and in the execution of such work. Covers actions required by the owner-user from initial receipt of the equipment on-site until final disposal. Applies to commissioning, operation, maintenance, routine inspection, storage and disposal, together with specific requirements for safety management systems, including, where appropriate, risk assessment. Applies to pressure equipment covered by AS/NZS 1200. The requirements do not apply to all hazard levels of pressure equipment.

This Standard specifies the requirements and gives guidance on the operation and maintenance of boilers, pressure vessels, associated control and safety equipment, piping and auxiliaries, (e.g. boiler fuel handling and firing equipment, heaters, fans, pumps, feedwater treatment and the like) and gives guidance in the execution of such work. It also covers actions required by the owner-user from initial receipt of the equipment on-site until final disposal.This Standard applies to commissioning, operation, maintenance, routine inspection, storage and disposal. It includes specific requirements for safety management systems, including where appropriate risk assessment.Requirements cannot be written in sufficient detail to cover all aspects of the above. Each owner-user is responsible for taking necessary action to ensure the continued safe operation of the pressure equipment. This may require the seeking of outside expert advice.This Standard applies to pressure equipment covered by AS/NZS 1200. However, all the requirements do not apply to all hazard levels of pressure equipment.
