1 Scope This standard describes a method for determining the resistance of coatings to neutral salt spray (fog). The method specified in this standard can be used to detect the mass of paints or coatings. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments to (excluding amending errors in the text), or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest edition of the normative document is applicable. For undated references, the latest edition of the normative document applies.
