1.1 <\/b>This part of ISO 8257 specifies procedures for moulding test specimens of PMMA materials in a specified state,<\/p>\n

and methods for measuring their properties. Any property listed in this part of ISO 8257 and referred to in combination<\/p>\n

with ISO 8257-1 shall be determined by the method referred to in this part of ISO 8257.<\/p>\n

1.2 <\/b>No values are quoted for these properties. Those required for the designation of PMMA materials for moulding<\/p>\n

and extrusion are given in ISO 8257-1. Other properties shall be determined by the appropriate methods referred to<\/p>\n

in this part of ISO 8257.<\/p>\n

1.3 <\/b>The values determined in accordance with this part of ISO 8257 will not necessarily be identical to those obtained<\/p>\n

using specimens of different dimensions and\/or prepared by different procedures. They may also be influenced<\/p>\n

by colorants and other additives. The values obtained for the properties of a moulding depend on the moulding<\/p>\n

compound, the shape of test specimen, the test method and the state of anisotropy. The last-mentioned depends on<\/p>\n

the gating and the moulding conditions, for example temperature, pressure or injection rate. Any subsequent treatment<\/p>\n

must also be considered, for example conditioning or annealing.<\/p>\n

1.4 <\/b>The thermal history and the internal stresses of the specimens may strongly influence thermal and mechanical<\/p>\n

properties and resistance to environmental stress cracking, but exert less effect on the electrical properties, which<\/p>\n

mainly depend on the chemical composition of the moulding compound.<\/p>\n","protected":false},"excerpt":{"rendered":"
