This document specifies a test method for determining the ability of a horizontal protective membrane, when used as a fire resistant barrier, to contribute to the fire resistance of standard horizontal structural building members as defined in 6.4.2. Test of horizontal protective membrane installed under a specific non-standard floor should be tested according to EN 1365-2. This document contains the fire test which specifies the tests which are carried out whereby the horizontal protective membrane, together with the structural member to be protected, is exposed to a fire test according to the procedures defined herein. The fire exposure, to the temperature/time curve given in EN 1363-1, is applied from below the membrane itself. The test method makes provision, through specified optional additional procedures, for the collection of data which can be used as direct input to the calculation of fire resistance according to the processes given within EN 1992-1-2, EN 1993-1-2, EN 1994-1-2 and EN 1995-1-2. This document also contains the assessment which provides information relative to the analysis of the test data and gives guidance for the interpretation of the results of the fire test, in terms of loadbearing capacity criteria of the protected horizontal structural member. In special circumstances, where specified in national building regulations, there can be a need to subject the protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in Annex C. The limits of applicability of the results of the assessment arising from the fire test are defined, together with permitted direct application of the results to different structures, membranes and fittings. This documentapplies only where there is a gap and a cavity between the horizontal protective membrane and the structural building member. Otherwise, the test methods in EN 13381-3, EN 13381 4 or EN 13381-5, as appropriate, apply. Tests are intended to be carried out without additional combustible materials in the cavity. Annex A gives details of assessing the performance of the ceiling when exposed to a semi-natural fire.

This European standard specifies the essential requirements of stationary systems for production of brines for winter road maintenance and includes tests of these requirements. Battery limits: chloride and water inlet to the saturator, brine outlet to the spreading machine. Within the scope are storage and loading/unloading equipment also. The following points are not covered by this standard: - System and construction requirements; - Requirements according national legislations.

This European Standard specifies the reference method for the determination of the concentration of gaseous hydrogen chloride (HCl) in waste gases emitted by industrial installations into the atmosphere. This voluntary European standard can be used in the measurements of HCl within the context of the conditions to be set out in permits issued according to the Industrial Emissions Directive (IED), in particular, for waste incineration plants and waste coincineration plants (Chapter IV and associated Annex VI of the IED). Currently, the European manual reference method, as described in EN 1911:2010, consists of the determination of all inorganic gaseous chlorides expressed as HCI. However, the emission limit value in.the lED (Annex VI) is targeting specifically gaseous hydrogen chloride (HCI) and not the other inorganic chlorides. Therefore, the availability of a new standardised method allowing the monitoring of emissions of hydrogen chloride (HCI) from the installations concemed as well as the calibration of on-site automated measurement systems is a necessary condition for the efficient implementation of the Directive. The European Commission (EC) has charged the European Committee for Standardization (CEN) to elaborate this new standard (With Mandate M/513 of January 2013). The work was allocated to CEN/TC 264 "Air quality"/WG 3 who has prepared a draft Technical Specification CEN/TS 16429 "Stationary source emissions – Sampling and determination of hydrogen chloride content in ducts and stacks – Infrared analytical technique”.

This document specifies an instrumental method for the routine determination of pH within the range pH 2 to pH 12 using a glass electrode in a 1:5 (volume fraction) suspension of soil, sludge and treated biowaste in water (pH in H2O), in 1 mol/l potassium chloride solution (pH in KCl) or in 0,01 mol/l calcium chloride solution (pH in CaCl2). This International Standard is applicable to all types of soil, sludge and biowaste, for example pretreated in accordance with ISO 11464 or EN 16179.
