This document is dealing with the sampling and testing of low VOC coating materials and their raw materials.
This part specifies a gas-chromatographic method of quantitatively determining the volatile organic compound (VOC) content (i.e. the content of organic compounds with boiling points up to 250 °C) under
standard conditions (101,325 kPa). It is applicable to VOC contents between 0,01 % and 0,1 % by mass.
ISO 17895 cannot be used for the determination of the SVOC content. For the determination of SVOC content ISO 11890-2 can be used.
Volatile organic and volatile inorganic compounds that cannot be determinded by gas chromatography are not considered in this document. However, the latter compounds could contribute to the VOC content determined by ISO 11890-1. These types of compounds could be determined with alternative methods and accounted for in the calculation as it is specified for water in ISO 11890-1.
The main purpose of the method is to qualify low-VOC coating materials and their raw materials, not routine quality control.
This document specifies a method for determining the density of paints, varnishes and related products using an oscillator.
The method is suitable for all materials, including paste-like coatings. If a pressure-resistant type of apparatus is used, the method is also applicable to aerosols.
This document provides pictorial reference standards for designating the degree of chalking of paint coatings. It also describes a method by which the degree of chalking is rated. In using this method, it is essential that care be taken to distinguish between true degradation products and adhering dirt,
particularly when chalking is slight.
