<p>ISO 7391-1:2006 establishes a system of designation for polycarbonate thermoplastic material, which may be used as the basis for specifications.</p>
<p>The types of polycarbonate plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties</p>
<ol><li>viscosity number</li><li>melt volume-flow rate</li><li>Charpy impact strength</li></ol>
<p>and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.</p>
<p>This part of ISO 7391 is applicable to thermoplastic polyesters of carbonic acid and aromatic dihydroxy compounds. The polyester may be a homopolymer, a copolymer or a mixture of the two.</p>
<p>It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc.</p>
