ISO 75-2:20 13规定了三种方法,使用不同的恒定弯曲应力值,可用于确定塑料(包括填充塑料和纤维增强塑料,其中纤维长度在加工前高达7.5 mm)和硬橡胶在载荷下的偏转温度:
方法A,使用1.80 MPa的弯曲应力;
方法B,使用0.45 MPa的弯曲应力;
方法C,使用8.00 MPa的弯曲应力。
ISO 75-2:2013 specifies three methods, using different values of constant flexural stress, which 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:
