36、ts for electromagnetic interference suppression which fall within the scope of the Generic Specification IEC 60939-1.The scope of this Sectional specification is restricted to passive filter units for which safety tests are appropriate. This implies that filters specified according to this Sectional

37、 specification will either be connected to mains supplies, when compliance with the mandatory tests of Table 3 is necessary, or used in other circuit positions where the equipment specification prescribes that some or all of these safety tests are required.This Sectional specification applies to pas

38、sive filter units which will be connected to an a.c. mains or other supply with a nominal voltage not exceeding 1 000 V a.c., with a nominal frequency not exceeding 400 Hz, or 1 000 V d.c.1.2Normative referencesThe following referenced documents are indispensable for the application of this document

45、specify requirements inferior to those of the generic, sectional or blank detail specification. When more severe requirements are included, they shall be listed in 1.9 of the detail specification, and indicated in the test schedules, for example by an asterisk.NOTE The information given in 1.3.2 may

46、, for convenience, be presented in tabular form.The following information shall be given in each detail specification and the values quoted shall preferably be selected from the appropriate clause of this sectional specification.1.3.2Outline draw ing and dimensionsThere shall be an illustration of t

47、he filter as an aid to easy recognition and for comparison of the filter with others. Dimensions and their associated tolerances, which affect inter- changeability and mounting, shall be given in the detail specification. All dimensions shall preferably be stated in millimetres.Normally, the numeric

48、al values shall be given for the length of the body, the width and height of the body and the wire spacing, or for cylindrical types, the body diameter and the length and diameter of the terminations. When necessary, for example when a range of filters is covered by a single detail specification, th

49、eir dimensions and their associated tolerances shall be placed in a table following the drawing.In addition, the detail specification shall state such other dimensional information as will adequately describe the filter outline.1.3.3MountingThe detail specification shall specify the method of mounti

50、ng recommended for normal use and the method which is mandatory for the application of the vibration, bump, shock and endurance tests. The design of the filter may be such that special mounting fixtures or heat sinks are required in its use. In this case, the detail specification shall describe the

51、mounting fixtures and they shall be used in the application of the vibration, bump or shock tests. The specified heat sink shall be used in the application of the endurance test.If recommendations for mounting for normal use are made, they shall be included in the detail specification under 1.8 Addi

52、tional information (not for inspection purposes). If they are included, a warning can be given that the full vibration, bump and shock performance may not be available if mounting methods other than those specified in 1.1 of the detail specification are used.1.3.4Ratings and characteristicsGe

53、neralThe ratings and characteristics shall be in accordance with the relevant clauses of this specification.Particular characteristicsAdditional characteristics may be listed when they are considered necessary to specify adequately the filter for design or application purposes.1.3.5MarkingThe

54、 detail specification shall specify the content of the marking on the filter and the package.1.4Terms and definitionsFor the purposes of this Sectional specification, the terms and definitions given in 2.2 ofIEC 60939-1, as well as the following apply.a.c. mains filter (or mains filter)passive filte

Such impulses may arise from lightning strikes on outside lines, from switching in neighbouring equipment, or switching in
