предговор
ИСО (Међународна организација за стандардизацију) је глобална федерација националних тела за стандардизацију (Тела чланица ИСО). Развој међународних стандарда се обично спроводи преко ИСО техничких комитета. Each member group interested in a subject on which a technical committee has been established has the right to be represented on the Committee. Governmental and non-governmental international organizations liaising with ISO are also involved in this effort. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електричне стандардизације.

The draft international standards adopted by the Technical Committee will be circulated to member bodies for voting. Публикација као међународни стандард захтева одобрење са најмање гласова 75% of the member body.

Међународни стандард ИСО 3549 was developed by the Technical Committee ISO/TC 35, Боје и лакови, Subcommittee SC 2, Pigments and Increments.

The second edition cancels and replaces the first edition (ИСО 3549:1976), which has been technically revised.

3 Дефиниција
For the purposes of this international standard, the following definitions apply.

3.1 Zinc powder pigment

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

Белешка 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.
