The scope of this European Standard is to establish heat exchanger terminology so that consistent terms are used. For the purposes of this European Standard a heat exchanger is a device, the main function of which is to transfer heat between two fluids, with physical separation by a wall. Heat exchange between a fluid and a solid material (in the case of ovens in particular) is therefore excluded.

The aim of this European Standard is: - to define the condition of the exposed surfaces of tapware, - to establish the characteristics (resistance to corrosion, adherence) of the surface coating, - to describe the tests for verifying these characteristics. It applies to all sanitary fittings (supply or waste fittings) which have a metallic Ni-Cr coating, whatever the nature of the substrate material.

This European Standard specifies requirements for the connecting dimensions for shower trays, regardless of the material used for their manufacture. This European Standard applies to shower trays used for domestic purposes and complements the standards for shower trays made from different materials, the existing standard on waste fittings (EN 274-1) in terms of their dimensional requirements. NOTE Only dimensions are compulsory. The shape of the appliance in the figures is for illustration only; it in no way prejudices the shape of the appliance which is left to the initiative of the manufacturer.

This European Standard specifies general construction, performance and material requirements for PN 10 thermostatic mixing valves (TMV) and includes test methods for the verification of mixed water temperature performance at the point of use below 45 °C. This does not exclude the selection of higher temperatures where available. When these devices are used to provide anti-scald protection for children, elderly and disabled persons the mixed water temperature needs to be set at a suitable bathing temperature (body temperature approximately 38 °C) as children are at risk to scalding at lower temperatures than adults. This does not obviate the need for supervision of young children during bathing. It applies to valves intended for use on sanitary appliances in kitchens, washrooms (incl. all rooms with sanitary tapware, e.g. toilets and cloakrooms) and bath rooms operating under the conditions specified in Table 1. This standard allows TMVs to supply a single outlet or a small number of outlets in a "domestic" application (e.g. one valve controlling a shower, bath, basin and/or bidet), excluding valves specifically designed for supplying a large number of outlets (i.e. for institutional use). The tests described are type tests (laboratory tests) and not quality control tests carried out during manufacture. Table 1 - Conditions of use

This International Standard establishes general actuating principles for manually operated actuators forming part of the man-machine interface associated with electrical equipment, in order to: – increase the safety (e.g. of persons, property, environment) through the safe operation of the equipment; – facilitate the proper and timely operation of the actuators. These principles apply, not only for the operation of electrical equipment, machines, or complete plant under normal conditions, but also under fault or emergency conditions. This standard is for general application, from simple cases such as single actuators (e.g. push-buttons) to multiple actuators, forming part of a large assembly of electrical and nonelectrical equipment, or part of a central process control station. This standard establishes correlations between the function of an actuator and its direction of actuating or location in relation to other actuators. In the absence of particular rules, this standard may also be applied to actuators operated by a part of the human body other than the hand (e.g. to foot-operated devices).

This section of IEC 721-3 defines classes of microclimatic conditions, to which components (basic parts, assemblies, built-in units) may be subjected inside products, which are used under the climatic conditions as classified in sections IEC 721-3-3 and IEC 721-3-4. Characteristic parameters for the microclimates are high air temperature and high relative air humidity. Further parameters of the climatic classes e.g. low temperature may affect the components additionally, but have not been considered here. A limited number of microclimatic classes is specified taking into consideration typical limiting high air temperatures of components. The user of this standard should select the lowest class necessary for covering the intended use

IEC Publication 721-3:Classification of Environmental Conditions, Part 3: Classification of Groups of Environmental Parameters and Their Severities, establishes classes of environmental parameters and their severities, covering the extreme (short-term) conditions which may be met by a product when being transported, installed, stored and used. Separate groups of classes are given for different product applications (e.g weather-protected stationary, mounted in ground vehicles, transportation). The classes also take into account the degree of restriction of the use of the product from very restricted conditions (e.g in temperature-controlled rooms) to unrestricted conditions. The classification covers natural as well man-made conditions
