1.1 This practice specifies the data recording information that is recorded, when data recording equipment is used, on butt fusion joints in a plastic piping system in order to compare the procedure used in making the joint to the heat butt fusion joining procedure specified. This practice is suitable for use with all heat butt fusion joining procedures that require measurable time and pressure profiles, such as Practice , Specification , Specification international standards or other qualified procedures. This practice applies to hydraulically operated heat butt fusion machines only and does not apply to manually operated fusion machines or specialized fabrication equipment for fittings in a controlled environment with proprietary procedures and processes.
1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.
