1.1 This specification contains various requirements that, with the exception of Sections 6 and 7 , are mandatory requirements to the following ASTM nickel and nickel alloy, longitudinally welded tubular product specifications: Title of Specification ASTM Designation Welded UNS N08020, N08024, and UNS N08026 Alloy Tubes B468 Welded UNS N08120, UNS N08800, UNS N08810, UNS N08811 Alloy Tubes B515 Welded Nickel-Chromium-Iron Alloy (UNS N06600, UNS N06603, UNS N06025, and UNS N06045) Tubes B516 Welded Nickel and Nickel-Cobalt Alloy Tube B626 UNS N08904, UNS N08925, and UNS N08926 Welded Tube B674 UNS N08366 and UNS N08367 Welded Tube B676 Welded UNS N06625, N06219, and N08825 Alloy Tubes B704 Ni-Cr-Mo-Co-W-Fe-Si Alloy (UNS N06333) Welded Tube B726 Welded Nickel (UNS N02200/UNS N02201) and Nickel Copper Alloy (UNS N04400) Tube B730 1.2 One or more of the test requirements of Section 6 apply only if specifically stated in the product specification or in the purchase order. 1.3 In case of conflict between a requirement of the product specification and a requirement of this general specification, only the requirement of the product specification need be satisfied. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
