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.

Увод
This document is one of a series of standards dealing with the sampling and testing of coating materials and their raw materials. It provides a method for the determination of volatile organic compound (ВОЦ) content and semi-volatile organic compound (SVOC) content of coating materials and their raw materials.

Warnings Use of this document may involve hazardous materials, операције, и опреме. Овај документ нема за циљ да одговори на све безбедносне проблеме повезане са његовом употребом. It is the responsibility of the user of this document to take appropriate steps to ensure the safety and health of personnel before applying the document and to determine whether any other restrictions are applicable for this purpose.

1 Обим
This document is suitable for the determination of VOC and/or SVOC with an expected VOC and SVOC content greater than 0.01 % (mass) до 100 %.

The method given in ISO 11890-1 is used when the VOC mass is greater than 15%. This document (method ISO 11890-2) is applicable when the system contains both VOC and SVOC, as the VOC results of ISO 11890-1 May be affected by SVOC. For VOC content of less than 0.1%, the headspace method described in ISO 17895 was used as an alternative. ИСО 11890-1 и ИСО 17895 cannot be used to determine SVOC content.

Белешка 1 Certain components of coating materials and their raw materials can decompose and cause artificial VOC and/or SVOC signals during analysis. These signals are artifacts of the method and are not taken into account when determining the VOC and/or SVOC of coating materials and their raw materials (examples are given in Annex B).

This method assumes that the volatile matter is water or organic matter. Међутим, other volatile inorganic compounds may be present and may need to be quantified by another suitable method and allowed in the calculations. The methods defined in this document are not applicable to the determination of moisture content.

Белешка 2 If organic acids or bases and their corresponding salts are present in the coating material or its raw materials, the amount quantified by this method may not be accurate due to changes in the acid or base balance.
