No figures are quoted for these properties. Those required for the designation of PMMA materials are given in ISO 8257-1. The values determined in accordance with this document will not necessarily be identical to those obtained using specimens of different dimensions and/or prepared by different procedures. They may also be influenced by colorants and other additives. The values of the properties depend on the moulding compound, the shape, the test method and the state of anisotropy. Methods for testing the mechanical, thermal and other relevant properties are given in a table. When measuring the properties, test specimens shall be subjected to pre-treatment by conditioning.
