12、an Australian Standard rather than an Australian/New Zealand Standard. The objective of this Standard is to provide manufacturers with design, materials and performance requirements for the protection of valves. Other Standards covering heated water system valves include the following: AS1357 Valves

14、ated devices 4032.3 Part 3: Requirements for field tesfting, maintenance or replacement othermostatic mixing valves, tempering valves and end of line temperature control devices The terms normative and informative have been used in this Standard to define the application of the appendix to which the

15、y apply. A normative appendix is an integral part of a Standard, whereas an informative appendix is only for information and guidance. Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of this Standard. 标准分享网 .bzfx免w费.c下o载m 3 AS 1357.12009CONTENTS P
