Materiale plastike - Përcaktimi i temperaturës së defleksionit nën ngarkesë - Pjesa 2: Materialet plastike dhe ebanitet

Plastics - Determination of temperature of deflection under load - Part 2: Plastics, ebonite and long-fibre-reinforced composites (ISO 75-2:2004)

Scope

ISO 75-2:2004 specifies three methods, using different values of constant flexural stress, that can be used for the determination of the temperature of deflection under load of plastics (including filled plastics and fibre-reinforced plastics in which the fibre length, prior to processing, is up to 7,5 mm) and ebonite:
method A, using a flexural stress of 1,80 MPa;
method B, using a flexural stress of 0,45 MPa;
method C, using a flexural stress of 8,00 MPa.
