What is this standard about?
ISO 2409 discusses paints and varnishes. ISO 2409 specifies a test method for assessing the resistance of paint coatings and varnishes to separation from substrates.
Although ISO 2409 is primarily intended for use in the laboratory, it’s also suitable for field testing. The test can be carried out on finished objects and/or on specially prepared test specimens.
The method applies both to paint on hard (e.g. metal) and soft (e.g. wood and plaster) substrates. These different substrates need a different test procedure.
Who is this standard for?
ISO 2409 on p aints and varnishes (cross-cut test) is useful for paint and coating manufacturers and anyone conducting laboratory or field testing of paints and varnishes, including:
