1、Designation: F3124 151An American National StandardStandard Practice forData Recording the Procedure used to Produce Heat ButtFusion Joints in Plastic Piping Systems or Fittings1This standard is issued under the fixed designation F3124; the number immediately following the designation indicates the
2、year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEThe title was editorially corrected and keywords were added
3、 in March 2015.1. Scope1.1 This practice specifies the data recording informationthat is recorded, when data recording equipment is used, onbutt fusion joints in a plastic piping system in order to comparethe procedure used in making the joint to the heat butt fusionjoining procedure specified. This
4、 practice is suitable for usewith all heat butt fusion joining procedures that requiremeasurable time and pressure profiles, such as Practice F2620,Specification F2785, Specification F2945 international stan-dards or other qualified procedures. This practice applies tohydraulically operated heat but
5、t fusion machines only and doesnot apply to manually operated fusion machines or specializedfabrication equipment for fittings in a controlled environmentwith proprietary procedures and processes.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use
6、. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

8、erally an electronic devicethat accepts sensor input for pressure and time and manualinput for other information. These Devices are typically small,battery powered, portable, and equipped with amicroprocessor, internal memory for data storage, and connec-tions for pressure sensors to the hydraulic f

Other Devices may have a local interfacedevice, such as a keypad or touch sensing, LCD display, andcan be used as a standalone device.4. Summary of P
10、ractice4.1 The principle of heat butt fusion of plastic pipe is toapply heat, at a designated temperature, to two prepared pipeends for a heat soak period and then fuse them together by theapplication of a sufficient force, thereby resulting in fusion.This practice identifies the information that is
11、 collected by thedata recording device about the heat butt fusion joint. TheDevice records the hydraulic pressures and times during thebutt fusion process for individual joints and manual entriessuch as operator identification, product information, fusionparameters, and heater surface temperature.5.
12、 Significance and Use5.1 The Device record includes information about how theheat butt fusion joint was made (heater temperature, pressuresand times for the heating, fusion and cooling steps) and otherimportant information about the process, job, equipment used,etc. The Device record is compared to
13、the specified heat buttfusion procedure parameters to determine if the procedure wasfollowed correctly. For comparison purposes, a graph of timeversus pressure is generated from the data record to showpressure changes that occur during the butt fusion process.Comparing the time versus pressure graph
14、 to the steps in theprocedure helps determine that the procedure parameters wereobserved. (See Appendix X1.) These records may be down-loaded from the device and stored.6.
