It is identical with and has be
12、en reproduced from ISO 7005-1:1992, Metallic flanges, Part 1: Steel flanges. The objective of this Standard is to provide designers, manufacturers and users with an international Standard for flanges for use in pressure applications. This Joint Standard is one of the following series that applies to
13、 metallic flanges. AS/NZS 4331Metallic flanges 4331.1Part 1:Steel flanges 4331.2Part 2:Cast iron flanges 4331.3Part 3:Copper alloy and composite flanges Under arrangements made between Standards Australia, Standards New Zealand and ISO, users of this Standard are advised that in Australia copyright
14、is vested in Standards Australia and in New Zealand copyright is vested in Standards New Zealand. It is not intended this Standard be a mandatory replacement for any flange Standards already in use in Australia or New Zealand. Before flanges to this Standard are used with flanges of other Standards,
15、 compatibility for bolting, strength, gasket seating and the like should be checked. Statements expressed in mandatory terms in notes to text, tables and figures are deemed to be requirements of this Standard. The terms normative and informative have been used in this Standard to define the applicat
16、ion of the annex to which they apply. A normative annex is an integral part of a Standard, whereas an informative annex is only for information and guidance. As this Standard is reproduced from an international Standard, the following applies: (a) Its number appears on the cover and title page while
17、 the International Standard number appears only on the cover. (b) In the source text, this International Standard should read this Australia/New Zealand Standard. (c) A full point substitutes for a comma when referring to a decimal marker. References to international Standards should be replaced by
18、equivalent Australian Standards, as follows: Reference to International StandardAustralian Standard ISO 7 7-1:1982 7-2:1982 Pipe threads where pressure-tight joints are made on the threads Part 1: Designation,dimensions and tolerances Part 2: Verification by means of limit gauges AS 1722 1722.1 1722
