3.1 These test methods are intended to compile as well as provide screening tests in evaluating clear and pigmented lacquers as used in different coating operations.
3.2 Each coating system may contain from a simple one coat operation to a multicoat finishing system.
3.3 The substrates may be varied, ferrous and non ferrous, plastic or wood which can affect the performance of a given coating system.
3.4 Substrate cleaning, chemically or physically, is an essential and critical aspect to the performance of the coating system.
3.5 Results from the various tests are not necessarily all useful in evaluating the performance of the different types of coating systems used on the many varied substrates.
