The scope of this European Standard is to define the classification for commercial beverage coolers and to specify their requirements and test methods. This European Standard is applicable to integral refrigeration systems. This European Standard is not applicable to remote and secondary system cabinets.

This document is applicable to the trenchless construction, trenchless replacement techniques and testing of new drains and new sewers in the ground usually operating as gravity or pressure pipelines, formed using prefabricated pipes and their joints.Renovation techniques for existing pressure and non-pressure systems are not covered by this document.Methods of trenchless construction include:- manned and unmanned techniques;- steerable and non-steerable techniques.Mining or tunnelling (e.g. in situ construction or the use of prefabricated segments) are not covered by this document although some parts may apply to these methods.Requirements for associated pipeline installation work other than trenchless construction, e.g. for manholes and inspection chambers, are not covered by this document and are specified in EN 1610. This also applies to pipes that are subsequently installed within entry and exit shafts/pits.

This document covers standardization in the field of geological and environmental aspects, design, drilling, construction, completion, operation, monitoring, maintenance, rehabilitation and decommissioning of borehole heat exchangers for uses of geothermal energy.The direct expansion and thermal syphon techniques are excluded from this document

This European Standard is applicable to sodium permanganate used for the treatment of water intended for human consumption. It describes the characteristics of sodium permanganate and specifies the requirements and the corresponding test methods for sodium permanganate. It provides information on its use in water treatment.

This European Standard is applicable to silver nitrate and silver sulfate and silver chloride for the preservation of water intended for human consumption in intermittent applications in:- water supply plants, including their pipeline networks (small-size plants);- water for the preparation of foodstuffs;- water which is stored in packaged form or kept in enclosed systems (for example, water supply systems in land, water and airborne vehicles).The purpose of adding silver salts is to prevent the detrimental proliferation of microorganisms in water during storage or in enclosed supply systems.This European Standard describes the characteristics of silver salts, specifies the requirements for silver salts and gives reference to the analytical methods. It gives information on their use in water treatment. It also determines the rules relating to safe handling and use of silver salts (see Annex B).

This document is applicable to sodium chloride intended for on site electrochlorination of water intended for human consumption using non-membrane technology. It describes the characteristics and specifies the requirements and the corresponding test methods for sodium chloride (see Annex B). It gives information on its use in water treatment.
