22、ic interference suppression which fall within the scope of the Generic Specification, EN 133000. The scope of this specification is restricted to passive filter units for which safety tests are not appropriate. This implies that filters specified according to this specification will not be connected
23、 to mains supplies that such tests are required. 1.2 Related documents EN 130400, Sectional Specification: Fixed metallized polyethylene-terephthalate film dielectric capacitors for direct current.

28、3 Information to be given in a detail specification The detail specification shall be derived from the relevant blank detail specification. Detail specifications shall not specify requirements inferior to those of the generic, sectional or blank detail specification. When more severe requirements ar
29、e included, they shall be listed in 1.9 of the detail specification, and indicated in the test schedules, for example by an asterisk. NOTEThe information given in 1.3.1 may for convenience be presented in tabular form. The following information shall be given in each detail specification and the val
30、ues quoted shall preferably be selected from the appropriate clause of this sectional specification. 1.3.1 Outline drawing and dimensions There shall be an illustration of the filter as an aid to easy recognition and for comparison of the filter with others. Dimensions and their associated tolerance
31、s, which affect interchangeability and mounting, shall be given in the detail specification. All dimensions shall preferably be stated in millimetres. Normally the numerical values shall be given for the length of the body, the width and height of the body and the wire spacing, or for cylindrical ty
32、pes, 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, their dimensions and their associated tolerances shall be placed in a table following the drawing. In addition the detail specifica
33、tion shall state such other dimensional information as will adequately describe the filter outline.

34、 of mounting 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 des
35、cribe the 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. 1.3.3 Ratings and characteristics The ratings and characteristics shall be in accordance with the relevant clau
36、ses of this specification. 1.3.3.1 Particular characteristics Additional characteristics may be listed when they are considered necessary to specify adequately the filter for design or application purposes. 1.3.4 Marking The detail specification shall specify the content of the marking on the filter
37、 and the package. 1.4 Terminology See 2.2 of EN 133000. 1.5 Marking 1.5.1 See 2.4 of EN 133000 with the following details: The information given in the marking is normally selected from the following list; the relative importance of each item is indicated by its position in the list: a) Manufacturer
38、s name or trademark; b) Manufacturers type designation or the type designation given in the detail specification; c) Rated voltage; d) Rated current; e) Identification of termination or circuit diagram; f) Rated temperature; g) Climatic category; h) Year and month (or week) of manufacture (may be in
39、dicated by the code given in IEC 60062); i) Reference to the detail specification. 1.5.2 Marking on the filter may be omitted when the manufacturer considers that there is insufficient space, and this fact is recorded in the detail specification. When present the marking shall be sufficient to provi
40、de a clear identification of the filter. 1.5.3 The package containing the filter(s) shall be clearly marked with all the information listed in 1.5.1. 1.5.4 Any additional marking shall be so applied that no confusion can arise. 2 Preferred ratings and characteristics 2.1 Preferred climatic categorie
41、s The filters covered by this specification are classified into climatic categories according to the general rules given in IEC 60068-1. The preferred values of lower and upper category temperature and the duration of the damp heat, steady state test are: Lower category temperature: 65 C, 55 C, 40 C
42、, 25 C and 10 C Upper category temperature: + 85 C, + 100 C, + 125 C and + 155 C Duration of the damp heat, steady state test: 4, 10, 21 and 56 days. The severities for the cold and dry heat tests are the lower and upper category temperatures respectively. For guidance on the application of the cate

These values conform to the basic series of preferred values R5 given in ISO 3: Preferred values R given in ISO 3: Preferred numbers. 2.2.2 Rated temperature The rated temperature shall not be less than + 40 C. 3 Quality assessment procedures 3.1 Primary stage of man
45、ufacture See 3.2 of EN 133000. 3.2 Structurally similar filters See 9 of EN 100114 Part 1 and 3.3 of EN 133000. In addition to these provisions, filters may be considered as structurally similar only when for their range of component values they have the same capacitor, inductor and resistor technol
46、ogies. 3.3 Certified records of released lots The information required in 3.5.1 of EN 133000 shall be made available when prescribed in the detail specification and when requested by a customer. After the endurance test the parameters for which variables information is required are insertion loss ch
47、ange and insulation resistance. 3.4 Qualification approval The procedures for qualification approval testing are given in 3.4 of the Generic Specification, EN 133000. The schedule to be used for qualification approval testing on the basis of lot-by-lot and periodic tests is given in 3.5 of this spec
48、ification. The procedure using a fixed sample size schedule is given in 3.4.1 and 3.4.2 below. For the two procedures the sample sizes and the number of permissible defectives shall be of comparable order. The test conditions and requirements shall be the same. Qualification approval according to th
49、e fixed sample size procedure is preferred. 3.4.1 Sampling The sample shall be representative of the range of filters for which approval is sought. This may or may not be the complete range covered by the detail specification. When there are not more than four rated voltages in the range the sample shall consist of specimens of four values, chosen as follows: a) The highest voltage and highest total capacitance; b) The highest voltage and lowest total capacitance; c) The lowest voltage and
