    Komite
    Beskrivelse
    Scope: The purpose of this document is to describe a procedure for the determination of the ester content in fatty acid methyl esters (FAME) intended for incorporation into diesel oil. It also allows determining the linolenic acid methyl ester content. It allows verifying that the ester content of FAME is greater than 90 % (m/m) and that the linolenic acid content is between 1 % (m/m) and 15 % (m/m). This method is suitable for FAME which contains methyl esters between C6 and C24. NOTE – For the purposes of this European Standard, the terms “% (m/m)” and “%(v/v)” are used to represent respectively the mass and volume fractions. Proposal of revision: This European Standard specifies a method for the determination of the methyl ester content of fatty acid methyl ester (FAME) fuels. In order to modify the requirements for the purity of standards, to include a procedure for the determination of the purity of standards and to improve the measurement of short chain FAMEs, The method needs to be revised to give optimal guidance to the user.

    This European Standard specifies the requirements for producing and inspecting girth, branch and fillet welds in the pipeline part of pipeline transportation systems for the petroleum and natural gas industries meeting the requirements of ISO 13623. On-land supply systems used by the gas supply industry are excluded from the scope of the International Standard. This European Standard is applicable to the requirements for welding of carbon and low-alloy steel pipes. Application is restricted to pipes with a diameter of 20 mm and larger and wall thickness of 3 mm or more, and a specified minimum yield strength of 555 MPa or less. It is also applicable to welding into pipelines, items such as spools, risers, launchers/receivers, fittings, flanges and ""pups"" to pipeline valves. The welding processes covered are shielded metal arc welding, gas tungsten arc welding, gas metal arc welding, flux-cored arc welding with and without shielding gas, and submerged arc welding. This European Standard is not applicable to flash girth welding, resistance welding, solid-phase welding or other one-shot welding processes, nor to longitudinal welds in pipe or fittings, to ""hot-tap"" welding of pipelines in service or to the welding of process piping outside of the scope of ISO 13623.

Part 1 of this European Standard describes the product characteristics and includes procedures for testing, evalua-tion of conformity, marking and labelling. This standard does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards. This European Standard does not cover factory made insulation products of formed shapes and boards made with expanded perlite. The products covered by this standard are not intended to be used primarily for airborne sound insulation or sound absorption applications although they may improve the performance of the buildings in these respects when installed for their primary thermal insulation intended use.
