前言
国际标准化组织 (国际标准化组织) 是国家标准机构的全球联合会 (ISO成员机构). 国际标准的制定通常通过ISO技术委员会进行. 每个对已成立技术委员会的主题感兴趣的成员团体都有权在委员会中派代表参加. Governmental and non-governmental international organizations liaising with ISO are also involved in this effort. ISO 与国际电工委员会密切合作 (国际电工委员会) 关于电气标准化的所有问题.

技术委员会通过的国际标准草案将分发给成员机构进行投票. 作为国际标准的出版需要至少获得投票批准 75% of the member body.

国际标准ISO 3549 由ISO/TC技术委员会制定 35, 油漆和清漆, 小组委员会SC 2, Pigments and Increments.

第二版取消并取代第一版 (国际标准化组织 3549:1976), 已进行技术修订.

3 定义
For the purposes of this international standard, 以下定义适用.

3.1 Zinc powder pigment

A fine gray powder of basically spherical particles, composed mainly of metallic zinc.

笔记 1: Zinc metal content, chemical purity, particle shape, particle size distribution, average and maximum diameter of zinc powder pigments used in coatings may vary. All of these changes may affect the behavior of zinc powder in coatings coating parameters such as dispersity, grinding fineness, reactivity, electrical conductivity and filling properties.
