- Scope
- 1.1 This specification covers circular contact-molded fiberglass reinforced-thermosetting-resin flanges for use in pipe systems and tank nozzles. Included are requirements for materials, workmanship, performance, and dimensions. 1.2 Flanges (see Fig. 1 ) may be produced as integral flanges, Type A, or flange-on-pipe, Type B. FIG. 1 Flange Types 1.3 This specification is based on flange performance and does not cover design. 1.4 These flanges are designed for use with pipe and tanks that are manufactured to Specifications D2996 , D2997 , D3262 , D3299 , D3517 , D3754 , and D4097 . 1.5 Selection of gaskets is not covered in this specification, refer to the manufacturer's recommendation. 1.6 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only. 1.7 The following precautionary caveat pertains only to the test methods portion, Section 9 , of this specification: 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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 1: There is no known ISO equivalent to this standard. 1.8 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.
