Bindemittel für Beschichtungsstoffe - Kolophonium - Gaschromatographische Analyse (ISO 19334:2010); Deutsche Fassung EN ISO 19334:2011
Overview
This standard specifies a gas-chromatographic method for determining the amounts of certain rosin acids in gum rosin using capillary gas-chromatographic separation of the volatile methyl esters of these acids. It is intended primarily to permit the identification of gum rosin from specific species of pine trees. It is not designed for the quantitative analysis of gum rosin. If such analyses are required, the internal-standard technique specified in ASTM D 5974 should be used. The Committee responsible for this standard is NA 002-00-02 AA "Lackrohstoffe" ("Raw materials for paints and varnishes").
