D.1 IntroductionThis annex describes procedures for sampling and measurement of VVOC and SVOC errussions in conjunction with voe emissions from building materials in test chambers and cells. VVOC and SVOC, compounds are conventionally regarded as those eluting before n-hexane and after n-hexadecane respectively on a non-polar (polydimethylsiloxane) column.This annex makes use of guidance provided in lSO 16017-1 on the selection and use of appropriate sorbents and analytical conditions for a wide range of vapour-phase organic compounds.
