Storage, distribution or use on network prohibited. AS 3920.119932 PREFACE This Standard was prepared by Standards Australia in conjunction with th
13、e National Occupational Health and Safety Commission (NOH and (b)the Special Premiers Conference held in October 1990 which highlighted the pressure equipment industry as one industry where regulatory review was required. Occupational health and safety regulating agencies have indicated their collec
14、tive view that QA could provide a framework by which manufacturers and suppliers could demonstrate compliance with the performance-based requirements of occupational health and safety legislation. However, it was recognized that QA alone would not provide full assurance in high hazard situations and
15、 that certain levels of external design verification and inspection of the product would be required, depending upon the hazard level. The hazard levels adopted in this Standard are comparable with those proposed by the European Community, Pressure Equipment Directive. ExistingStandardsforpressureeq
16、uipmentcomeunderthegeneralbannerof AS/NZS 1200Pressure equipment. The Standards referenced in AS/NZS 1200 specify inspection requirements but do not deal with QA aspects. These Standards are largely based upon traditional legislative requirements which involve inspection by the regulating authoritie
17、s. Newer style occupational health and safety legislation requires manufacturers, suppliersandownerstotakefullresponsibilityfortheiractivitieswithpressure equipment. To assist in this process and to align with leading world practice, this Standard requires traditional external third-party inspection
18、 for more hazardous equipment but reduces this requirement where certified quality systems are in use. This Standard is a new edition to the Standards referenced in AS/NZS 1200 and applies to boilers, pressure vessels and piping. Such equipment is a component of general hazardous plant and thus the
19、concepts of QA and hazard levels contained in this Standard may apply to other hazardous plants. Also, in forming this Standard its important relationship with occupational health and safety legislation and the proposed NOH and the design and equipment already verified or approved do not require rev
20、erification in accordance with this Standard. Subsequent alterations, however, are the subject of this Standard.
