(50 mm) in thickness.本规范涉及两片厚度为2英寸（50毫米）的可焊接热塑材料之间焊缝的准备和评价。可焊接热塑材料分为有背衬和无背衬两种，如表1所示。 1.2 Since there are numerous new technologies and techniques constantly being developed for plastic welding, there are no profiles and procedures that can be considered as standard for all plastics at various thicknesses. This practice is not intended to define profiles and procedures; however, it is intended to establish methods to evaluate minimum short term weld factors to be achieved by the welder for the respective plastics.塑性焊接的大批新技术和新工艺正在不断发展，但具有不同厚度的塑料没有标准的型材和程序。本规范将不会对型材和程序进行规定，而是建立如何对焊工焊接各塑料时所实现的最小短期焊接系数进行评价的方法。 1.3 Weld procedures used for test pieces should reflect procedures to be used in actual f
