21、 Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 27/08/2010 04:17, Uncontrolled Copy, (c) BSIEN 50491-2:2010 4 Introduction The EN 50491 series deals with developing and testing Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS). The expression HBES/BACS covers an

22、y combination of HBES and/or BACS devices including their separate connected/detachable devices linked together via one or more networks. Part 2 of this series applies to HBES/BACS devices and defines the environmental conditions for these devices. 1 Scope This European Standard provides the environ

23、mental conditions for all devices connected to HBES/BACS. This European Standard is applicable (but not limited) to - operator stations and other human system interface devices, - devices for management functions, - control devices, automation stations and application specific controllers, - field d

24、evices and their interfaces, - cabling and interconnection of devices, - dedicated devices for engineering and commissioning tools for HBES/BACS. The standard defines the general requirements for devices operating in weather protected and non-weather protected locations, ship environments, portable

25、use and also for storage and transport. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendme

35、3.1 product documentation set of documents that may contain any of the following: - the manufacturers installation and operations literature which accompanies the product; - the product information contained in the manufacturers catalogue and other product marketing material-information; - the descr

36、iption, definitions, product literature and usage as presented in electronic format on the manufacturers (or suppliers) website on the World Wide Web/Internet 3.2 weather protected locations: controlled conditions locations that are enclosed, and where direct weather influences are totally excluded.

37、 In addition, temperature is controlled by heating or cooling to maintain the required conditions, especially where these are very different from those of the open-air climate. Humidity is not controlled. Vibration and shock are insignificant. These locations may be in rural and some urban areas wit

38、h low industrial activities and moderate traffic. There is no particular risk of biological attack due to mould growth, animals, etc. EXAMPLES: - normal living or working areas, for example living rooms, and rooms for general use such as theatres, restaurants, offices, shops, workshops for electroni

40、ocations that are enclosed, but whether direct weather influences are not completely excluded.In addition, neither temperature nor humidity is controlled, although heating may be used to raise low temperatures where there is a large difference between the conditions of this class and those of the op

41、en-air-climate. Vibration is of low significance. EXAMPLES: - entrances and staircases of buildings, garages, cellars, and certain workshops; - buildings in factories and industrial process plants; - unattended equipment stations, certain telecommunication buildings, ordinary storage; - rooms for fr

42、ost-resistant products, farm buildings, etc. 4 General explanation for all tests The variety and the diversity of the devices within the scope of this standard make it difficult to define precise criteria for the evaluation of the immunity test results. If, as a result of the application of the test

43、s defined in this standard, the device becomes dangerous or unsafe, the device shall be deemed to have failed the test. 5 Environmental conditions 5.1 General test conditions The HBES/BACS devices shall be designed for use in one or more of the environment classes according to the classification in

44、the EN 60721-3 series as indicated in Table 6.1 up to Table 6.4. All test procedures are described in the EN 60068 series. Environmental tests shall be applied in accordance with the test method in the relevant basic standard of the EN 60068 series. In addition the following shall apply: - the devic

45、e shall be in operation during all tests except those for storage and transportation; - the tests shall be made in the most susceptible operating mode; - it is not always possible to test every function of the devices, and in such cases the most critical mode of operation shall be selected; - the te

46、sts shall be carried out as single tests in sequence. The sequence of testing is optional; - the description of the test, the test method and the test set-up are given in basic standards (EN 60068-x-x) which are referred to in the following tables; - the content of these basic standards is not repea

47、ted here. However, details of modifications and other information needed for the practical application of the tests are given in this European Standard. 5.2 General performance criteria During (except for storage and transportation) and after all tests the device shall not block the transmission med

48、ia or send unintended telegrams. A functional description and a definition of performance criteria, during or as a consequence of environmental testing, shall be provided by the manufacturer and noted in the test report, based on the following criteria.
