Changes to standards and technical documents updated by CEN that affect those carrying out chemical measurement in support of regulation
The following list shows standards and technical documents published by the European Standardisation Organisation, CEN, during March and April, some of which are relevant to chemical measurement in support of regulation.
EN ISO 6885:2016 - Animal and vegetable fats and oils: determination of anisidine value.
EN ISO 4938:2016 - Steel and iron: determination of nickel content - gravimetric or titrimetric method.
EN ISO 4946:2016 - Steel and cast iron: Determination of copper - 2,2’-Biquinoline spectrophotometric method.
EN ISO 13904 - Animal feeding stuffs: Determination of tryptophan content
EN ISO 4859-2:2016 - Steels - Determination of total silicon contents: Reduced molybdosilicate spectrophotometric method - Part 2: Silicon contents between 0.01 % and 0.05 %.
EN ISO 22155:2016 - Soil quality: Gas chromatographic determination of volatile aromatic and halogenated hydrocarbons and selected ethers - Static headspace method.;
EN ISO 15009:2016 - Soil quality: Gas chromatographic determination of the content of volatile aromatic hydrocarbons, naphthalene and volatile halogenated hydrocarbons - Purge-and-trap method with thermal desorption.
CEN/TS 16916:2016 - Materials obtained from End of Life Tyres: Determination of specific requirements for sampling and determination of moisture content using the oven-dry method. This specifies a method for determining the total moisture content of materials obtained from End of Life Tyres by drying samples in an oven, and is applicable to chips, granulates, powders and textile derived from the treatment of End of Life Tyres, but is not intended for the determination of moisture content in steel wires.
