标准摘要
[中文适用范围]： ISO 1628 的这一部分描述了测定聚碳酸酯在稀溶液中的粘度值（也称为比浓粘度）和相对粘度所需的条件。 它可用于纯聚碳酸酯和与其他聚合物的共混物，以及两者的混合物，无论有或没有填料，如 ISO 7391-1 中所定义。 [外文原描述]： This part of ISO 1628 describes the conditions necessary for the determination of the viscosity number (also known as the reduced viscosity) and the relative viscosity of polycarbonates in dilute solution. It can be used for pure polycarbonates and blends with other polymers, as well as mixtures of both, with or without fillers, as defined in ISO 7391-1.
