This document specifies test methods for smoke control dampers to assess their performance under elevated temperature or fire conditions. It is of note that the smoke control damper to be tested could require testing to EN 1366 2 and that this is for consideration before carrying out these tests. Smoke control damper tests are used to confirm that the furnace testing requirements of EN 12101 8 are met and EN 12101 8 is for consideration before carrying out these tests. Smoke control dampers tested to this document are expected to be classified using EN 13501 4 and this document is expected to be considered before carrying out these tests. To this end, this document is expected to be read in conjunction with EN 12101 8, EN 13501 4, EN 1366 2 and EN 1363 1, the latter giving further details for fire resistance testing. For installation details, the requirements for smoke extraction ducts are for consideration and these are defined in EN 1366 8 and EN 1366 9.

The European Standard test method is designed to produce measurements of explosion pressure and the maximum explosion pressure, the rate of explosion pressure rise and the maximum rate of explosion pressure rise of a quiescent flammable gas/air/inert mixture in closed volume at ambient temperature and pressure. In this European Standard, the term "gas" includes vapours but not mists. Detonation and decomposition phenomena are not considered in this European Standard. The pressures and rates of pressure rise measured by the procedures specified in this European Standard are not applicable to flameproof enclosures, that is enclosures intended to withstand an internal explosion and not to transmit it to an external explosive atmosphere, or any other closed volume where the internal geometry can result in pressure piling. Even in an enclosure of relatively simple geometry the disposition of the internal components can lead to rates of pressure rise significantly higher than those measured using this European Standard. This European Standard does not apply to the design and testing of flameproof enclosures in conformity with EN 13463-6 (for non-electrical equipment) and EN 60079-1 (for electrical equipment).

This European standard describes a test method for laboratory evaluation of possible adverse effects of water treatment membranes on drinking water quality. In principle it is applicable to microfiltration, ultrafiltration, nanofiltration, reverse osmosis and electrodialysis modules for use in the treatment of public water supplies and of water inside buildings. NOTE Such devices can vary considerably in design and operation and hence some modification of the procedures may be required. Evaluation of the efficiency of the membrane filter in removing contaminants from the treated water is not included.

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.
