12、as prepared by the Joint Standards Australia/Standards New Zealand Committee ME/1, Pressure Equipment to supersede AS 40371992, Boilers and pressure vesselsExamination and testing. This Standard is the result of a consensus among representatives on the Joint Committee to produce it as a Joint Austra
13、lian/New Zealand Standard. Consensus means general agreement by all parties. Consensus includes an attempt to remove all objections and implies much more than the concept of a simple majority, but not necessarily unanimity. It is consistent with this meaning that a member may be included in the Comm
14、ittee list and yet not be in full agreement with all clauses of this Standard. The objective of this Standard is to reduce misunderstanding, costs and delays in non- destructive examination, improve safety, prevent unnecessary duplication of tests and promote greater confidence in reciprocal accepta
15、nce of approved procedures. This Standard is one of the core documents which form part of the revised arrangement of the pressure equipment Standards under the umbrella of AS/NZS 1200, Pressure equipment. The first issue of the Standard unified and replaced the requirements for the non- destructivee
