увод
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 електричне 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, треба обратити пажњу на различите критеријуме одобрења који су потребни за различите типове ИСО докумената.

ИСО 15110-2017 “Artificial ageing of paints and varnishes including acid deposition”

Voluntary, related standards and conformity assessment related ISO specific and express the meaning of terminology as well as in relevant ISO technical barriers to trade (ТБТ) adhere to the principle of the world trade organization (WTO) information, please refer to the following URL:iso.org/iso/foreword.html.

This document was prepared by Technical Committee ISO/TC 35, Боје и лакови, Subcommittee SC 9, Common Test Methods for paints and varnishes.

The second edition cancels and replaces the first edition (ИСО 15110:2013), which has been technically revised. Главне промене у односу на претходно издање су следеће:

– Scope is limited to paints and varnishes;

A black panel thermometer was added to the fluorescent UV lamp, as it provides the same results as the BST UV-F device;

Uncontrolled humidity exposure has been listed as a new UADF test because it has been shown that humidity control does not affect the precise type of damage caused by this test.

увести
This document specifies a method for modeling the destructive effects of outdoor weathering associated with acidic atmospheric precipitation on painted products. The mechanism is different from that of harmful gases, which are basically the initial products of acid precipitation.

Acidic precipitation occurs occasionally due to changes in industrial air pollution, coupled with the spread of random wind and cloud distribution. Стога, especially in the case of acidic precipitation, outdoor weathering effects vary greatly from year to year. As a result, it is almost impossible to get reliable outdoor exposure results from just one season. These fluctuations can be avoided by using laboratory tests in which all weathering parameters, including acid deposition, can be controlled.

This method is based on VDI guideline VDI 3958-12[9].

This document specifies the so-called acid Dew and Fog test (ADF test) as an accelerated laboratory test method to simulate the damaging effects of acidic atmospheric precipitation associated with ultraviolet radiation, neutral condensing precipitation, and temperature and humidity changes by using artificial acidic precipitation. This test method is designed to evaluate the suitability of paint materials for use in acidic precipitation outdoor environments based on relative performance rankings. It is not intended to produce the same degree of damage or the same pattern of damage as outdoor weathering, but rather to give a ranking similar to outdoor weathering. The method produces more uniform damage, allows fewer specimens to be exposed (so testing is faster), and enables exposure specimens to be evaluated using a more objective method than visual assessment.
