Scope

This document describes the method of determining the VOC and/or SVOC content using gas chromatography.
This document is applicable to the determination of VOC and SVOC content where the expected VOC and/or SVOC content is greater than 0.01% (by mass) and less than or equal to 100% (by mass).
When the VOC content is greater than 15% (by mass), the method specified in ISO 11890-1 is used for determination. The VOC content measured according to ISO 11890-1 may be affected by SVOC, so when the system contains both VOC and SVOC, the determination is carried out according to this document (GB/T 23986.2). When the VOC content is less than 0.1% (by mass), the headspace method described in ISO 17895 can also be used for determination. ISO 11890-1 and ISO 17895 cannot be used to determine the SVOC content.
