19、sed for testingelectromechanical components within the scope of IEC technical committee 48. This test mayalso be used for similar devices when specified in a detail specification.The object of this test is to define a standard test method for the visual examination ofelectromechanical components.2 G

20、eneralThe visual examination checks the identification, appearance, workmanship and finish of anitem against the relevant specification. Optical aids, as specified in clause 4, should be usedwhen specified by the detail specification.The visual examination is to a certain extent a subjective method.

21、 Care must be taken tocome to a fair judgement. Defects, deviations from a given standard or changes due tostresses must be carefully differentiated according to their importance or significance.3 Features to be examinedThe following features shall be examined:a) workmanship and finish;b) marking;c)

22、 materials;d) surface finish, for example: traces of corrosion; colour (comparison with applicable colour standards or samples); degree of lustre (comparison with an applicable standard, for example Bolls scale orsample); roughness, grooves, waves, scratches, furrows, holes, pores, depressions, cres

23、ts,scales, cracks, burrs, flash, etc.; foreign material in and on the surface;e) internal conditions of translucent materials (for example cavities, gaseous inclusions andflow lines, including inclusions of foreign matter);f) condition and location of a lubricant (as far as can be visually ascertain

24、ed);g) loosened and detached parts (especially after stress).Page 3EN 6051211:2002 BSI 27 May 2002065-21-11 g211 EI:C0022 4 4 Method of visual examinationThe visual examination shall be carried out by one of the following methods:a) with the naked eye (normal strength of vision, normal colour percep

25、tion, at the mostfavourable viewing distance and with suitable illumination);b) with magnification, if specified.For the purpose of this standard, special methods, for example using polarized light (forobserving internal tensions in materials) or other indicators (for observing internal materialcrac

26、ks or pores), are not permitted, unless explicitly required by the detail specification.5 Details to be specifiedWhen this test is required by the detail specification, the following details shall be specified:a) details to be examined;b) features to be checked;c) deficiency criteria;d) power of mag

27、nification, if specified;e) any deviation from the standard test method._Page 4EN 6051211:2002 BSI 27 May 2002BS EN 60512-1-1:2002BSI389 Chiswick High RoadLondonW4 4ALBSI British Standards InstitutionBSI is the independent national body responsible for preparing British Standards.
