GB/T 2546.2-2022 Plastics—Polypropylene(PP) moulding and extrusion materials—Part 2:Preparation of test specimens and determination of properties
Abstract
This document specifies the methods and conditions for the preparation of samples and performance determination of polypropylene (PP) molding and extrusion materials. This document also stipulates the requirements for the pretreatment of test materials and the adjustment of the state of samples before testing.
This document lists the appropriate and necessary performance and test methods for characterizing polypropylene (PP) molding and extrusion materials. These performances are selected from GB/T 19467.1 General Test Methods. This document also lists other test methods widely used or of particular significance for molding and extrusion materials, as well as the determination methods for the named performance in Part 1.
In order to ensure the reproducibility and repeatability of test results, it is necessary to use the methods specified in this document for sample preparation and state adjustment, as well as the specified sample sizes and test methods. Test data obtained from samples prepared under different conditions or using different sample sizes may be inconsistent.
