25、ment against external mechanical impacts. Whilst this system is suitable for use with most types of electrical equipment, it should not be assumed that all the listed degrees of protection are applicable to a particular type of equipment. The manufacturer of the equipment should be consulted to dete

26、rmine the degrees of protection available and the parts of equipment to which the stated degree of protection applies. The adoption of this classification system, wherever possible, should promote uniformity in methods of describing the protection provided by the enclosure and in the tests to prove

27、the various degrees of protection. It should also reduce the number of types of test devices necessary to test a wide range of products. 1 Scope This standard refers to the classification of the degrees of protection provided by enclosures against external mechanical impacts when the rated voltage o

28、f the protected equipment is not greater than 72,5 kV. This standard is only applicable to enclosures of equipment where the specific standard establishes degrees of protection of the enclosure against mechanical impacts (expressed in this standard as impacts). The object of this standard is to give

29、: a) the definitions for degrees of protection provided by enclosures of electrical equipment as regards protection of the equipment inside the enclosure against harmful effects of mechanical impacts; b) the designations for the degrees of protection; c) the requirements for each designation; d) the

30、 tests to be performed to verify that enclosure meets the requirements of this standard. It will remain the responsibility of individual Technical Committees to decide on the extent and manner in which the classification is used in their standards and to define “enclosure” as it applies to their equ

31、ipment. However, it is recommended that for a given classification the tests do not differ from those specified in this standard. If necessary, complementary requirements may be included in the relevant product standard. For a particular type of equipment a Product Committee may specify different re

32、quirements provided that at least the same level of safety is ensured. This standard deals only with enclosures that are in all other respects suitable for their intended use as specified in the relevant product standard and which from the point of view of materials and workmanship ensure that the c

33、laimed degrees of protection are maintained under the normal conditions of use. This standard is also applicable to empty enclosures provided that the general test requirements are met and that the selected degree of protection is suitable for the type of equipment. 2 Normative references This Europ

34、ean Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications

37、ose of this standard, the following definitions apply. 3.1 enclosure 1) a part providing protection of equipment against certain external influences and, in any direction, protection against contact (IEV 826-03-12) NOTE This definition from the existing International Electrotechnical Vocabulary (IEV

38、) needs the following explanations under the scope of this standard: 1) Enclosures provide protection of equipment against harmful effects of mechanical impacts. 2) Barriers, shapes of openings or any other means whether attached to the enclosure or formed by the enclosed equipment suitable to preve

39、nt or limit the penetration of the specified test probes are considered as a part of the enclosure, except when they can be removed without the use of a key or tool. 3.2 degree of protection against mechanical impacts the extent (level) of protection of the equipment provided by an enclosure against

40、 harmful mechanical impacts and verified by standardized test methods 3.3 IK code a coding system to indicate the degree of protection provided by an enclosure against harmful mechanical impacts 4 Designations The degree of protection provided by an enclosure against impacts is indicated by the IK c

41、ode in the following way. 4.1 Arrangement of the IK code 4.2 Characteristic group numerals of the IK code and their meanings Each characteristic group numeral, represents an impact energy value as shown in Table 1. Table 1 Relation between IK code and impact energy NOTE 1 When higher impact energy i

42、s required the value of 50 Joules is recommended. NOTE 2 A characteristic group numeral of two figures has been chosen to avoid confusion with some former national standards which used a single numeral for a specific impact energy. 4.3 Application of the IK code In general the degree of protection a

43、pplies to the complete enclosure. If parts of the enclosure have differing degrees of protection, the latter shall be separately indicated. 1) This definition is identical to 3.1 of EN 60529.

Where appropriate, su

45、ch a standard should also specify the method of marking which is to be used when: one part of an enclosure has different degree of protection to that of another part of the same enclosure; the mounting position has an influence on the degree of protection. 5 General requirements for tests 5.1 Atmosp

46、heric conditions for tests Unless otherwise specified in the relevant product standard, the test shall be carried out under the standard atmospheric conditions for tests described in IEC 60068-1 as: When the altitude at which the test is performed is higher than 2 000 m the height of fall shall be a

47、djusted where necessary to result in the specified impact energy. 5.2 Enclosures under test Each enclosure under test shall be in a clean and new condition, complete with all their parts in place unless otherwise specified in the relevant product standard. 5.3 Specifications to be given in the relev

48、ant product standard The relevant product standard shall specify: the definition of “enclosure” as it applies to the particular type of equipment; the test equipment (e.g. pendulum hammer, spring hammer or vertical hammer, see Clause 7); the number of samples to be tested; the conditions for mountin

49、g, assembling and positioning the samples, e.g. by the use of an artificial surface (ceiling, floor or wall), in order to stimulate intended service conditions as far as possible; the pre-conditioning, if any, which is to be used; whether to be tested energized; whether to be tested with any moving parts in motion; the number of impacts and their points of application (see 6.3).
