This document specifies a method for the direct determination of water in ethanol to be used as a blending component for petrol, as well as in automotive ethanol (E85) fuel.This method is applicable in the range 0,05 % (m/m) to 0,54 % (m/m).NOTE For the purposes of this document, the term "% (m/m)" is used to represent the mass fraction.WARNING - Use of this document might involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This European Standard is valid for vehicles equipped with buffers and screw coupling systems.In order to allow operation and coupling of trainsets or vehicles, this European Standard specifies the defined free space for the shunter called the "Berne rectangle" and the necessary free space for the installation of the rescue coupler.This European Standard specifies the location, fixing and free spaces on the headstock of:- buffers;- screw coupling systems;- end cocks;- pneumatic half couplings;- connections for electric cables.It also specifies the calculation of the width of the buffer heads.Unless otherwise displayed, all dimensions given in this European Standard are nominal values.

This standard specifies a qualitative method, by thermographic examination, for detecting thermal irregularities in building envelopes. The method is used initially to identify wide variations in the thermal properties, including air tightness, of the components constituting the external envelopes of buildings.
