предговор
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 тој комисији. Међународне владине и невладине организације које су у вези са ИСО такође су укључене у овај посао. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електротехничке стандардизације.

Процедуре које се користе за израду овог документа и оне које се користе за даље одржавање описане су у Делу 1 ИСО/ИЕЦ директиве. Нарочито, обратите пажњу на различите стандарде одобрења који су потребни за различите типове ИСО докумената. Овај документ је израђен у складу са правилима уређивања у Дел 2 ИСО/ИЕЦ директиве (види исо.орг/дирецтивес).

This document has been prepared by ISO/TC 35 (Боје и лакови) Technical Committee, SC 9 Sub-Committee (General test methods for paints and varnishes) in cooperation with the Technical Committee CEN/TC 139 (Боје и лакови) of the European Committee for Standardization (CEN) in accordance with the ISO/ CEN Technical Cooperation Agreement (Vienna Agreement).

The third edition cancelled and replaced the technically revised second edition (ИСО 20566:2013). Главне промене у односу на претходно издање су следеће:

– Термин “Control panel” has been changed to “reference Panel”;

— The requirement on the temperature of washing suspension is deleted;

– Verification using plastic panels is added to Appendix A;

— The text has been edited and revised, and the normative references have been updated.

Any feedback or questions about this document should be directed to the user’s national standards body. A complete list of these institutions can be found at iso.org/members.html.

ИСО 20566-2020 “Боје и лакови – Determination of scrubbing resistance of coating systems by laboratory car cleaning methods”

увести
With this testing procedure, it is important to note that test results do not remain the same over time due to changes in brush materials. As brushes age, the testing will become more serious. Стога, the test program is only suitable for comparison tests performed at any time, and uses relatively short runs. Readings obtained using devices that accumulate different total hours of operation are not comparable to each other.

1 домет
This document specifies test procedures for assessing the scratch resistance of organic paint coatings, particularly those used in the automotive industry (тј. for assessing their car wash resistance). Machine-based washing is simulated in a laboratory environment using a rotating brush and synthetic dirt. The test conditions are designed to be as close as possible to the real conditions at the car wash. This method can also be used to test protective plastic films and plastic parts if the test parameters are selected properly.
