PREFACE
This Standard was prepared by the Joint Standards Australia/Standards New Zealand
Committee ME-001, Pressure Equipment, to supersede AS/NZS 3992:1998, Boilers and
pressure vessels—Welding and brazing qualification.
The objective of this Standard is to reduce misunderstanding, costs and delays in qualifying
welding, avoid unnecessary duplication of testing, promote greater confidence in reciprocal
acceptance of approved procedures, and improve safety. It also aims for greater alignment
with ASME and ISO Standards, and to be consistent with the current work health and safety
laws.
This Standard unifies and revises the requirements for the qualification of welding and
brazing procedures, welding and brazing personnel, and production test plates and welds,
specified in AS 1210, Pressure vessels, AS 1228, Pressure equipment—Boilers, and
AS 4041, Pressure piping.
This Standard is a major revision of AS/NZS 3992:1998 based on AS 1210, with due
allowance for latest practices or requirements of AS 1210, AS 1228 and AS 4041.
