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 fourth edition cancels and replaces the third edition of the technical revision (ИСО 16053:2018).

ИСО 16053-2022 “Natural Aging test of coatings and paint systems for Outdoor Wood Products with colors and varnishes”

The main changes are as follows:

– Updated regulations on the use of alternative timber species;

— Internal comparison product (ICP) has been replaced by the nominated reference material as weathering reference material (WRM);

– Mold growth assessment has been extended to visual disfiguement of microorganisms;

– Delete the original annex A;

– A new annex G on typical characteristics of common timber species has been added;

– Added a new appendix H for tape testing;

– New annex I on thermal/chemical modification of wood has been added;

This file has been edited and revised.

ИСО 16053-2022 “Natural Aging test of coatings and paint systems for Outdoor Wood Products with colors and varnishes”

1 Обим
This document provides for natural weathering testing of exterior wood coating systems primarily used for the decoration and protection of planed and sawn timber.

This test provides a way to evaluate the performance of a wood coating system during outdoor exposure. It forms the basis for the performance specification in compliance with EN 927-2. It also facilitates the comparison of coating system performance on different substrates, including wood species or other wood modifications.

See Annex E for details.
