本文件规定了最小基本变量，以便为以下热连接工艺生产具有所需一致性和质量的部件: -超声波焊接/铆接/点焊； -红外焊接； -热气体对流焊接； -线性振动焊接； -轨道振动焊接； -旋焊； -激光焊接； -热板焊接； -热铆接:热空气； -热铆接:电气；和 -热铆接:红外（IR）。 本文件规定了上述每种热连接工艺的热连接工艺规范（TJPS），以确保正确考虑所有基本变量，包括每个变量的合格范围，从而将部件质量建立并保持在可接受水平。 注:ISO/TC 138制定并维护了塑料管、配件、阀门和/或辅助设备的连接标准，以及由此产生的接头性能评估。

This document specifies the minimum essential variables in order to produce a component of the required consistency and quality for the following thermal joining processes: — ultrasonic welding/staking/spot welding; — infrared welding; — hot gas convection welding; — linear vibration welding; — orbital vibration welding; — spin welding; — laser welding; — hot plate welding; — heat staking: hot air; — heat staking: electrical; and — heat staking: infrared (IR). This document defines the thermal joining process specification (TJPS) for each of the thermal joining processes listed above, to ensure that all the essential variables are properly considered, including the qualified range of each variable, in order to establish and maintain component quality at an acceptable level. NOTE Standards on joining of plastic pipes, fittings, valves and/or auxiliary equipment, and the assessment of the properties of the resulting joints are developed and maintained by ISO/TC 138.
