ISO 1043-2:2011规定了填料和增强材料术语的统一符号。它只包括已确定使用的符号，其主要目的是防止给定填料或加固材料出现一个以上的符号，并防止给定符号以一种以上的方式解释。

ISO 1043-2:2011 specifies uniform symbols for terms referring to fillers and reinforcing materials. It includes only those symbols that have come into established use, and its main aim is both to prevent the occurrence of more than one symbol for a given filler or reinforcing material and to prevent a given symbol being interpreted in more than one way.
