scope:

This Standard specifies general methods for determining the resistance of an individual-layer or multi-layer system of paints or related products to the effects of liquids.

This Standard specifies four types of test methods, from which an appropriate method will be selected according to the material to be tested. These methods enable the testers to determine the effects of the test substance on the coating and, if necessary, to assess the damage to the substrate.

NOTE 1 This Standard is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products.

NOTE 2 The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 2812-1: 2007 Paints and varnishes-Determination of resistance to liquids-Part 1: Immersion in liquids other than water

ISO 2812-3: 2012 Paints and varnishes-Determination of resistance to liquids-Part 3: Method using an absorbent medium

ISO 2812-4: 2007 Paints and varnishes-Determination of resistance to liquids-Part 4: Spotting methods

ISO 2812-5: 2007 Paints and varnishes-Determination of resistance to liquids-Part 5: Temperature-gradient oven method (overall evaluation: MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ lEC Guide 21-1
