<p>ISO 9988-1:2004 establishes a system of designation for polyoxymethylene (POM) thermoplastic materials, which may be used as the basis for specifications.</p>
<p>The types of polyoxymethylene plastic are differentiated from each other by a classification system based on appropriate levels of the following designatory properties:</p>
<ol><li>melt mass-flow rate or melt volume-flow rate,</li><li>tensile modulus,</li></ol>
<p>and on information about basic polymer parameters, intended application, method of processing, important properties, additives, colorants, fillers and reinforcing materials.</p>
<p>This part of ISO 9988 is applicable to all polyoxymethylene homopolymers and to copolymers of polyoxymethylene and blends of polymers containing polyoxymethylene.</p>
<p>It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified and modified by colorants, additives, fillers, etc.</p>
