标准摘要
[中文适用范围]： 本标准规定了测定天然橡胶溶解在四氢呋喃中的平均分子量和分子量分布的方法。 一组聚苯乙烯标准品用于校准目的（即该方法是相对方法）。 另一种方法是使用环己烷作为溶剂和聚异戊二烯标准品，包含在资料性附录中。 [外文原描述]： ISO 16564:2004 specifies a method of determining the average molecular mass and the molecular-mass distribution of raw natural rubber dissolved in tetrahydrofuran. A set of polystyrene standards is used for calibration purposes (i.e. the method is a relative one). An alternative method, using cyclohexane as solvent and polyisoprene standards, is included in an informative annex.
