Popis
BS EN ISO 19334:2011
This standard BS EN ISO 19334:2011 Binders for paints and varnishes. Gum rosin. Gas-chromatographic analysis is classified in these ICS categories:
- 87.040 Paints and varnishes
- 87.060.20 Binders
This International 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.
