The method applied shall be indicated in the list of properties for every test specimen, using “Q” as the code-lette
15、r for compression moulding. It is essential that all specimens prepared by a par- ticular method are prepared using the same process- ing conditions given in tables 1 and 2. 3.1 Treatment of the material before moulding Before compression moulding, the material shall be preplasticized in a two-roll
