適用范圍：This International Standard specifies a method for carrying out an indentation test on a single coating or multicoat system of paint, varnish or related product, using a specified instrument (Buchholz).The length of the indentation produced when an indentor of specified size and shape is applied to the coating under def ined conditions is indicative of the residual deformation of the coating. The result is expressed as a function of the reciprocal of the indentation length and this increases as the desired property (resistance to indentation) increases.NOTES1 Since the indentation test, like other physical tests on paints, gives results which may be dependent upon time, temperaturs and humidity, comparable results will only be obtained if the test is carried out within well-defined conditions.2 Since the indentation depth depends upon the film thickness, the result obtained for indentation resistance is only valid if the coating thickness exceeds a minimum value (see 5.3.2).
