This part of GB/T l7037 specifies two standard molds with two cavities of type D1 and type D2, which are used for injection molding small square test pieces of 60 mm × 60 mm, and the thickness of the test piece is 1 mm (type D1) and 2 mm. (Type D2). Test strips can be used for a variety of tests (see Appendix A). In addition, molds can be fitted with inserts to study the effect of weld lines on mechanical properties (see Appendix B).
