1 范围 本标准规定了天然生胶六个等级的最低质量要求和相应的检验方法。 本标准适用于我国各级别的天然生胶标准橡胶。 除恒粘胶(CV)和浅色胶(L)之外,生胶各个级别都是以其杂质含量的最高数值来定名的,而恒粘胶和浅色胶则根据规定的特性,如恒粘胶级别以粘度稳定度来定名,而浅色胶级别以浅色来定名。恒粘胶和浅色胶的最高杂质含量与5号胶相同。 2 引用标准 下列标准包含的条文,通过在本标准中引用而构成为本标准的条文。本标准出版时,所示版本均为有效。所有标准都会被修订,使用本标准的各方应探讨使用下列标准最新版本的可能性。 GB/T 1232-1992 未硫化橡胶门尼粘度的测定( neq ISO 289:1985) |

3 取样
天然生胶应按GB/T 15340进行取样或按有关协定的方法取样。
4 要求
4.1 按本标准规定供应的生胶不得含有胶清橡胶。
4.2 批样中的每一个胶包都应进行检验,以确定是否符合表1所列的技术要求。
注:一般认为杂质含量和塑性保持率(PRI)是主要的规格参数。
