本标准于1987年7月首次发布。本标准规定了天然生胶和胶乳中微量 锰含量的测定——高碘酸钠光度法。本标准适用于天然生胶和胶乳中微量 锰含量的测定。本标准与ISO7780:1998相比主要差异如下:
———本标准仅适用于天然生胶和天然胶乳中微量锰含量的测定,删去了与此无关的部分。
本标准代替GB/T8296—1987《天然胶乳 锰含量的测定(高碘酸钾光度测定法)》。
本标准与GB/T8296—1987相比主要差异如下:
———采用的国际标准不同,由于GB/T8296—1987参照采用的ISO1655:1975《生胶和胶乳 锰含
量的测定(高碘酸钾光度法)》已被废止,本标准修改采用ISO7780:1998;
———标准的适用范围扩大到天然生胶中微量锰含量的测定;
———使用的锰标准溶液的浓度由20mg/L 改为10mg/L,并多提供了一种配制方法;
———使用的标准配比溶液由0mL、0.25mL、0.50mL、0.75mL、1.00mL、1.25mL、1.50mL 改为0mL~10mL,从而更易于操作和减少操作误差。


Scope

WARNING: Personnel applying this standard should have practical experience in formal laboratory work. This section does not address all possible security issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. This standard specifies the method for the determination of trace manganese content in natural raw rubber and latex—sodium periodate photometry. This standard applies to the determination of trace manganese content in natural raw rubber and latex.
