Scope

This document specifies methods for the preparation of test specimens AND the
determination of properties, for polyoxymethylene molding and extrusion materials.
This document specifies the handling of the tested material, as well as the state
conditioning requirements for the tested material prior to molding and the specimen
prior to testing. This document specifies the methods and conditions for specimen
preparation, as well as the method for measuring the specimen.
This document applies to POM molding and extrusion materials.
This document lists properties and test methods, for characterizing polyoxymethylene
molding and extrusion materials. These properties are selected from general test
methods. Some other particularly important or widely used test methods, for POM
molding and extrusion materials, are also covered in this document, along with
characteristic properties: melt flow rate and tensile modulus of elasticity.
In order to obtain comparable and reproducible test results, it is intended to be carried
out, in accordance with the sample preparation process and state conditioning method,
sample size, test method, which is specified in this document. Test data, which uses
different specimen sizes or specimen preparation methods, may not be consistent.
