What are the commonly used international standards for the determination of VOC content?

At present, the international general definition of VOC in coating products refers to any organic liquid or solid that can evaporate on its own under the normal temperature and pressure of the atmosphere in contact with the coating product. Generally, any organic compound with a boiling point of no more than 250 ° C at atmospheric pressure is defined as volatile organic compound (VOC).

different ranges of VOC content can be measured by different methods.

At present, there are 4 international standards for the determination of VOC content:

1.ISO 11890 ) 1, Paints and varnishes-Determination of volatile organic compound (VOC) content-Part 1: Difference method;

2.ISO 11890 ) 2, Paints and varnishes-Determination of volatile organic compound (VOC) content-Part 1: Gas chromatographic method;

3.ISO DIS 17895, Paints and varnishes-Determination of volatile organic compound (VOC) content in water-based latex paints;

4.ASTM D 3960 ) 02 Determination of volatile organic compound (VOC) content in paints and related coatings.
