GB/T 17037.1-2019 is the English-translated version of 塑料热塑性塑料材料注塑试样的制备第1部分：一般原理及多用途试样和长条形试样的制备.

GB/T 17037.1-2019 is the Chinese standard "Plastics -- Injection moulding of test specimens of thermoplastic materials -- Part 1: General principles, and moulding of multipurpose and bar test specimens".

Its scope clause reads: This part of GB/T 17037 gives the general principles followed by injection molding of thermoplastic materials and is given for the preparation of two Detailed reference data for the mold design of the sample, such as the A1 and B1 specimens specified in GB/T 37426, provides reproducible injection molding The purpose of the condition is to provide a consistent description of the main parameters of the molding process and to establish a uniform method under the reported molding conditions.

Sample The detailed conditions required for reproducibility preparation will vary depending on the materials used, as specified in the national standards for the relevant materials, or As agreed by the relevant parties.

This section applies to thermoplastic materials injection molding to produce reproducible multi-purpose samples and long strip samples. Note.

Experiments between laboratories of acrylonitrile/butadiene/styrene (ABS), styrene/butadiene (SB) and polymethyl methacrylate (PMMA) have shown that Mold design is one of the important factors to ensure the reproducibility of the sample. Its clauses include terms and definitions.

1 Scope

This part of GB/T 17037 gives the general principles followed by injection molding of thermoplastic materials and is given for the preparation of two

Detailed reference data for the mold design of the sample, such as the A1 and B1 specimens specified in GB/T 37426, provides reproducible injection molding

The purpose of the condition is to provide a consistent description of the main parameters of the molding process and to establish a uniform method under the reported molding conditions. Sample

The detailed conditions required for reproducibility preparation will vary depending on the materials used, as specified in the national standards for the relevant materials, or

As agreed by the relevant parties.

This section applies to thermoplastic materials injection molding to produce reproducible multi-purpose samples and long strip samples.

Note. Experiments between laboratories of acrylonitrile/butadiene/styrene (ABS), styrene/butadiene (SB) and polymethyl methacrylate (PMMA) have shown that

Mold design is one of the important factors to ensure the reproducibility of the sample.
