Standardisation procedure is based on internationally established principles. A standardisation project is undertaken only when some responsible interest asks for it. The project is worked out by a committee appointed by the Council and represents all the main interested groups. A committee first drafts a specification and circulates it for comment to the manufacturing, distributing, user, professional, scientific, and other interests affected. The draft specification is also sent for comment and advice to the national standards organisations of other English-speaking countries. The committee then studies all comment received to see if the draft needs changing in order to make it the best possible statement and definition of commercial, industrial, or technological practice. It is then referred to the Minister. If he agrees with the draft he formally declares it a New Zealand Standard Specification. The new standard is then gazetted and printed for general use.
