1 Scope This standard is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products. This standard specifies a general procedure for determining the resistance of single coating or multi-coating systems of paints, varnishes or related products to changes in gloss and/or color, blistering, cracking and/or detachment from the substrate under conditions of moderately elevated temperature. 2 Normative References The following standards contain provisions which, through reference in this standard, constitute provisions of this standard. For dated references, all subsequent modifications (excluding correction contents) or revisions are not applicable to this standard. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest editions of these documents are applicable.
