Paints and varnishes - Cross-cut test
Executive summary
Cross-cut test method for the sampling and testing of paints, varnishes and related products.
Abstract
This International Standard is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products. It specifies a test method for assessing the resistance of paint coatings to separation from substrates when a right-angle lattice pattern is cut into the coating, penetrating through to the substrate.
The main differences between BS 3900-E6:1974 and this standard, are as follows:
a) in the procedure, the spacing of cuts is prescribed, depending on the
thickness of the coating and the type of substrate;
b) for hard substrates application of adhesive tape has been added.
History and related standards
This International Standard supersedes BS 3900-E6:1974, which is withdrawn.
This standard includes the following cross references:
ISO 1512:1991, ISO 1513, ISO 1514, ISO 2808:1991, ISO 3270:1984, and
IEC 454-2:1974.
