Significance and Use
5.1 The Device record includes information about how the heat butt fusion joint was made (heater temperature, pressures and times for the heating, fusion and cooling steps) and other important information about the process, job, equipment used, etc. The Device record is compared to the specified heat butt fusion procedure parameters to determine if the procedure was followed correctly. For comparison purposes, a graph of time versus pressure is generated from the data record to show pressure changes that occur during the butt fusion process. Comparing the time versus pressure graph to the steps in the procedure helps determine that the procedure parameters were observed. (See .) These records may be downloaded from the device and stored.
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.
