CEN updates: information affecting chemical measurements Dec 2015
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 November and December, some of which are relevant to chemical measurement in support of regulation.
EN 16711-1:2015 - Textiles - Determination of metal content - Part 1: Determination of metals using microwave digestion, which specifies a procedure for determination of metals, in particular antimony (Sb), arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), mercury (Hg), nickel (Ni) in natural and man-made textiles.
EN 16711-2:2015 - Textiles - Determination of metal content - Part 2: Determination of metals extracted by acidic artificial perspiration solution, which specifies a procedure for determination of antimony (Sb), arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), mercury (Hg), nickel (Ni) in natural and man-made textiles after extraction with acidic artificial perspiration solution. EN ISO 18122:2015 - Solid biofuels - Determination of ash content, applicable to all solid biofuels.
EN ISO 18123:2015 - Solid biofuels - Determination of the content of volatile matter, which aims to define the requirements and method used to determine the volatile matter content of solid biofuels. The volatile matter content is determined as the loss in mass, less that due moisture, when solid biofuel is subject to partial pyrolysis under standardized conditions.
EN 15991:2015 - Testing of ceramic and basic materials - Direct determination of mass fractions of impurities in powders and granules of silicon carbide by inductively coupled plasma optical emission spectrometry (ICP OES) with electrothermal vaporisation (ETV), which defines a method for the determination of the trace element concentrations of Al, Ca, Cr, Cu, Fe, Mg, Ni, Ti, V and Zr in powdered and granular silicon carbide. Dependent on element, wavelength, plasma conditions and weight, this test method is applicable for mass contents of the above trace contaminations from about 0.1 mg/kg to about 1000 mg/kg, after evaluation also from 0.001 mg/kg to about 5000 mg/kg.
EN 10361:2015 - Alloyed steels - Determination of nickel content - Inductively coupled plasma optical emission spectrometric method for the determination of nickel content (mass fraction) between 5.0 % and 25.0 % in alloyed steels. The method does not apply to alloyed steels having niobium and/or tungsten contents higher than 0.1 %.
EN 16761-1:2015 - Automotive fuels - Determination of methanol in automotive ethanol (E85) fuel by gas chromatography - Part 1: Method using single column technique. The measurement range for the methanol is from about 0.5 % (V/V) to about 1.5 % (V/V).
EN 16761-2:2015 - Automotive fuels - Determination of methanol in automotive ethanol (E85) fuel by gas chromatography - Part 2: Method using heart cut technique. This specifies a determination method of methanol in automotive ethanol (E85) fuel by capillary gas chromatography using heart cutting technique and flame ionization detection and is applicable to fuels having a methanol content from about 0.5 % (V/V) to about 1.5 % (V/V).
CEN ISO/TS 8000-1:2015 - Nanotechnologies - Vocabulary - Part 1: Core terms.
EN 16785-1:2015 - Bio-based products - Bio-based content - Part 1: Determination of the bio-based content using the radiocarbon analysis and elemental analysis, which specifies a method of determining the bio-based content in products, based on radiocarbon analysis and elemental analysis. It applies to any solid, liquid and gaseous product containing the element carbon, provided that a statement giving the composition and the origin of the product is available. This method is not needed for the determination of the bio based content in natural products wholly derived from biomass.
