This document amends EN IEC 63341-2 which applies to onboard hydrogen fuel systems used to supply the fuel cells for the traction power and the auxiliaries supply of rolling stock vehicles (such as hybrid vehicles as defined in EN IEC 62864-1). NOTE 1 This document may also be used as informative recommendations for applications with hydrogen internal combustion engines. EN IEC 63341-2 applies to hydrogen storage in gaseous form. Other means of storage (such as liquid, liquid cryo-compressed, metal hydrides) are not covered in this document. EN IEC 63341-2 applies to any rolling stock type (e.g. light rail vehicles, tramways, streetcars, metros, commuter trains, regional trains, high speed trains, locomotives). EN IEC 63341-2 addresses the mechanical, fluidic and electrical interfaces between the on-board hydrogen fuel system and fuelling station. The fuelling station, fuelling protocol and communication for the fuelling protocol are not in the scope of this document. EN IEC 63341-2 defines: – the scope of supply of hydrogen fuel system (HFS) and the description of the interfaces with sub-systems internal and external to the rolling stock such as fuel cell power system, fuelling station systems; – the environmental constraints; – the design requirements to support HFS compliance with railway applications; – the safety and reliability requirements to design and install the HFS for railway applications; – the marking and labelling requirements; – the requirements related to storage, transportation, installation and maintenance; – the validation (type, routine and investigation tests) requirements

Cemento bandymų metodai. 10 dalis. Vandenyje tirpaus chromo (VI) kiekio cemente nustatymas

This document specifies the method for the determination of the water-soluble chromium (VI) content of cement. A reference method is described consisting of two stages, an extraction procedure and an analysis of the filtered extract. Guidance on other extraction procedures, suitable for screening tests, for factory production control or other purposes, is given but in case of dispute or failure to comply with a regulatory limit only the reference method is used. The reference method has alternatives whereby the filtered extract can be subjected to an oxidation step or not. The criteria by which the appropriate procedure is selected are set down. Other instrumental procedures can be used for the analysis of the filtered extract provided they are calibrated against the analysis of the filtered extract using the reference procedure. In the case of a dispute, only the reference method is used. This document specifies, for the determination of water-soluble chromium (VI) in the filtered extract, the reference methods (colorimetric determination by diphenylcarbazide in acidic conditions) and another method for the determination of total water-soluble chromium (by inductively coupled plasma optical emission spectroscopy, ICP-OES). The ICP-OES determines the total chromium content independently of the chemical species, i.e. whether it is present as chromium (III) or chromium (VI), for example. Experience has demonstrated that soluble chromium (VI) is predominantly present during the processing phase, such that, in most cases, the determination of total water-soluble chromium effectively reflects the chromium (VI) content. The water-soluble chromium (VI) content of cement can therefore be assessed conservatively using the method based on ICP-OES described in this document. In the case of a dispute, only the reference methods are used. This document specifies a method that applies to cements. NOTE 1 Annex A provides guidance on the possible application of this document to the determination of the water-soluble chromium (VI) content of cement-containing preparations. NOTE 2 Annexes B and C provide information on other test procedures based on paste extraction and thus depart from the performance of cement in its normal conditions of use. They can be carried out with or without the oxidation process. It is important that users are aware that results using these methods might be significantly different to those obtained by the reference method. In the case of dispute or failure to comply with the regulatory limit, only the reference method is used. NOTE 3 Annex D provides guidance on a method for determination of the excess reducing agent content of cement as used in the factory internal control system of some countries. It is important that manufacturers using such an internal control method ensure themselves of the relevance of results in comparison with testing by the reference method.
