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 11997-2-2013 Coatings and varnishes – Determination of cyclic corrosion resistance conditions – Парт 2: wet (со спреј)/ dry/humidity /UV light

The committee responsible for this document is ISO/TC 35, Боје и лакови, Subcommittee SC 9, Common Test Methods for Paints and varnishes.

The second edition cancels and replaces the technically revised first edition (ИСО 11997-2:2000). The main technological changes are:

а) Alternative test procedures are added as an information annex;

б) Supplementary test conditions (original Annex A) have been included in the test report.

ИСО 11997 састоји се од следећих делова, under the general heading Paints and varnishes – Determination of resistance to cyclic corrosion conditions:

– Парт 1: Мокар (со спреј)/Dry/humidity

– Парт 2: Мокар (со спреј)/Dry/humidity/UV

Овај део ИСО-а 11997 is equivalent to ASTM D 5894, Standard Practice for painted metal cycle salt spray/UV exposure (alternating exposure in fog/drying cabinets and UV/condensing cabinets).

ИСО 11997-2-2013 Coatings and varnishes – Determination of cyclic corrosion resistance conditions – Парт 2: wet (со спреј)/ dry/humidity /UV light

увести
Paints, лакови, and coatings of similar materials use specified salt solutions in cabinets under cyclic wet corrosion and UV exposure conditions in order to simulate in the laboratory the processes that occur under corrosive outdoor conditions. Генерално, since there are many factors that affect the breakdown process, a valid correlation between such outdoor aging and laboratory testing cannot be expected. Certain relationships can only be expected if important parameters such as the properties of contaminants, spectral distribution of incident irradiance in the relevant photochemical region, temperature of the specimen, wetting type and cycle, and relative humidity are known to affect the coating. Compared to outdoor weathering, the number of variables for laboratory testing in the cabinet is reduced and can be controlled, so the effect is more repeatable.

The method described may provide a way to check whether the quality of the paint or paint system is being maintained. The method is designed to provide a more realistic simulation of these factors than traditional tests of continuous exposure to a set of static corrosion conditions. The method has been found to be useful for comparing the cyclic salt spray tolerance of different coatings. It is useful to provide relevant ratings for a range of coated panels that show significant differences in cyclic salt spray/UV exposure resistance tested at the same time and within the same test cycle.

The cycle specified in this part of ISO 11997 has been found to be useful for air drying industrial maintenance coatings on steel; Other loops can be used as needed.
