BS EN ISO 11890-2:2020 pdf free.Paints and varnishes — Determination of volatile organic compounds (voc) and/or semivolatile organic compounds (svoc) content.
1.scope:This document is applicable for the determination of vOC and SVoC with an expected VOCand/or sVoc.content greater than 0,01 % by mass up to 100 % by mass.The method given in IS0 11890-1 is used when the vOC is greater than 15 % by mass. This document(method lso 11890-2) applies when the system contains vocand svoCas the voC result of lSO 11890-1can be influenced by the SVoC.For VOC content smaller than 0,1 %, the head space method described inIS017895 is used as an alternative.ISO 11890-1 and ISo 17895 cannot be used for the determination ofthe svoc content.
NOTE1 Some ingredients of coating materials and their raw materials can decompose during analysis andcause artificial voc and/or svoC signals. When determining VOC and/or svoC for coating materials and theirraw materials, these signals are artefacts of the method and are not taken into account (examples are givenin Annex B).This method assumes that the volatile matter is either water or organic. However,other volatileinorganic compounds can be present and might need to be quantified by another suitable method andallowed for in the calculations.The method defined in this document is not applicable for determinationof water content.
NOTE2 lf organic acids or bases and their corresponding salts are present in the coating material or its rawmaterials, the amount that is quantified by this method might not be accurate due to a change in the acid or baseequilibrium.

For dated references, only the edition cited applies. Forundated references, the latest edition of the referenced document (including any amendments) applies.
