Nothing in this specificatio
17、n, however, shall supersede applicable laws and regulations unless a specific exemption has been obtained. 3 REQUIREMENTS 3.1 Specification sheets. The individual item requirements shall be as specified herein and in accordance with the applicable specification sheet. In the event of any conflict be
18、tween requirements of this specification and the specification sheet, the latter shall govern. 3.2 Material. Fittings shall be made of material conforming to QQ-C-390, alloy C90300 or C92200 or to ASTM B 61 (UNS no. C92200) bronze at the nanufac- turers option. Fittings made of material conforming t
19、o MIL-B-16541 is an acceptable substitute for QQ-C-390 alloy C90300, C92200 or ASTM B 61 (UNS no. C92200). 3.2.1 Recovered materials. Unless otherwise specified herein, all material incorporated in the products covered by this specification shall bc new and may be fabricated using materials produced
20、 from recovered materials to the maxinum extent practicable without jeopardizing the intended use. The term “recovered materials“ means materials which have been collected or recovered from solid waste and reprocessed to become a source of raw materials, as opposed to virgin raw materials. None of t
21、he above shall be interpreted to mean that the use of used or rebuilt products is allowed under this specification unless otherwise specifically specified. 3.3 Configuration and dimensions. Fitting configuration and dimemions shall be in accordance with figures 1 or 2 and table I of this specific-ti
22、on and applicable figures and tables of the specified specification sheet .!see 6.2).
