Description / Abstract:
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 F2620, Specification F2785,
Specification F2945 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.
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.
