А Префаце
ИСО (Међународна организација за стандардизацију) је глобални савез националних тела за стандардизацију (Тела чланица ИСО). Развој међународних стандарда се обично спроводи преко ИСО техничких комитета. Свака институција чланица заинтересована за предмет за који је основан технички комитет има право да буде заступљена у комитету. У овај посао су укључене и владине и невладине међународне организације које су у вези са организацијама за стандардизацију. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електричне стандардизације.

The committee responsible for this document is ISO/TC 35, Боје и лакови, Subcommittee SC 9, General test methods for paints and varnishes.

The third edition removes and replaces the second edition (ИСО 4624:2002), which was technically revised with the following changes:

ИСО 4624-2016 Боје и лакови – Adhesion test by drawing method

а) Added detailed information on how to avoid substrate deformation during tensile testing;

б) The three methods of using one cart or two carts and two carts (one for the paint substrate) on the painted panel have been named methods A, B and C;

ц) The supplementary test conditions previously in Annex A have been incorporated into the test report.

Увод
This International standard is one of two standards describing a method for assessing the adhesion of a single or multi-coating system of paint, varnish or related products by measuring the minimum tensile stress required to separate or break the coating in a direction perpendicular to the substrate.

Test results are influenced not only by the mechanical properties of the system under test, but also by the nature and preparation of the substrate, method of paint application, coating drying conditions, температура, humidity and other factors such as the type of test instrument already used.

Another international standard for assessing bonding properties is ISO 2409.

1 Обим
This standard specifies three methods (тј. paint on the front panel of a car or two cars, one as coating substrate), through a single coating of paint, varnish, or related products or multi-layer coating system on the pull off test to determine the adhesion.

These test methods can be used to compare different coating adhesion behavior. It is most applicable to provide a relative rating for a range of coated panels that exhibit significant differences in adhesion.

The test can be performed using a variety of substrates. Different procedures are given depending on whether the substrate is deformable, such as thin metal, plastic and wood, or rigid, such as thick concrete and metal plates. To avoid substrate deformation during tensile testing, a sandwich structure is usually used. На пример, for a special purpose, coating can be directly coated on the surface of test cart.
