【国外标准】 Standard Specification for Butt Heat Fusion Polyamide(PA) Plastic Fitting for Polyamide(PA) Plastic Pipe and Tubing

This specification covers polyamide (PA) butt fusion fittings for use with polyamide pipe (IPS and ISO) and tubing (CTS). This specification covers butt fusion fittings intended for use with polyamide pipe and tubing. Fittings covered by this specification are normally molded. Fittings may be machined from extruded or molded stock. Conditioning, dimensions and tolerances, short-term rupture strength, sustained pressure test, and minimum hydrostatic burst pressure test shall be performed to conform with the requirements specified.1.1 This specification covers polyamide (PA) butt fusion fittings for use with polyamide pipe (IPS and Metric) and tubing (CTS). Included are requirements for materials, workmanship, dimensions, marking, sustained pressure, and burst pressure.1.2 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.1.3 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.1.4 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.
