Introduction

GB/T 41877 is the basic standard for the classification and nomenclature, sample preparation and performance determination of ethylene-vinyl alcohol copolymer resins. The evaluation and application of vinyl alcohol products and the formulation of product standards provide support. Since ISO 21309 consists of two parts, the national standard During the conversion process, the structure was kept consistent with ISO 21309. GB/T 41877 consists of two parts. --- Part 1.Nomenclature system and classification basis; --- Part 2.Sample preparation and performance determination. All specimen preparation, conditioning, specimen dimensions, and test conditions specified in this document are intended to provide reproducibility and comparability. Plastic Ethylene Vinyl Alcohol (EVOH) Copolymer molding and extrusion materials Part 2.Specimen preparation and performance determination

1 Scope

This document specifies the methods and conditions for the preparation and determination of properties of ethylene-vinyl alcohol (EVOH) molding and extrusion materials. this document It also specifies requirements for the pretreatment of the test material and the conditioning of the specimens prior to testing. This document lists properties and test methods suitable and necessary to characterize ethylene vinyl alcohol (EVOH) molding and extrusion materials. these sexes can be selected from the general test methods of GB/T 19467.1.This document also lists molding and extrusion materials that are widely used or have special Other test methods of significance, and the method for determination of melt mass flow rate specified in GB/T 41877.1. In order to ensure the reproducibility and reproducibility of test results, it is necessary to use the methods of sample preparation and condition adjustment specified in this document to and the specified sample size and test method. Test data obtained using specimens prepared under different conditions or using specimens of different sizes can be can be inconsistent.
