scope:

This Standard specifies several types of standard panels and describes procedures for their preparation prior to painting. These standard panels are for use in general methods of test for paints, varnishes and related products. The product needs to be tested on an agreed surface which is capable of good reproducibility. It is desirable to use a material that is generally available in standard quality and can be conveniently cleaned or otherwise prepared so as to provide a consistent surface. The fact that this may not necessarily be the type of surface on which the product will be applied in practice is of less significance.
