The UK participation in its preparation was entrusted to Technical Committee EPL51, Iliansfonners, inductors, magnetic components and ferrite materials, which has the responsibility to: - aid enquirers to understand the text; - present to the responsible in

A list of organizations represented on this committee can be obtained on request to i
5、ts secretary. From 1 January 1997, aJ IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as lEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems.
6、 Cross-references Attention is dram to the fact that CEN and CENELEC Standardc normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications m

22、- Part 6: Sectional specification for inductors on the basis of the capability approval procedure 1 Scope This part of IEC 1248 specifies how to prepare detail specifications for inductors to be released under the terms of IEC 1248-1 (QC 260000) capability approval. It includes a blank detail specif
23、ication (BOS), which shows the format and indicates which tests are considered to be appropriate to this type of component, although the final selection of tests to be included in the inspection schedule is at the discretion of the specification writer. It also lists appropriate ratings and characte
24、ristics. 2 Normative references The following normative documents contain provisions, which, through reference in this text, constitute provisions of this pari of IEC 1248. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to
25、agreements based on this part of IEC 1248 are encouraged to investigate the possibility of applying the most recent editions of the normative documents listed below.

32、ion of detail specifications for inductors released under the terms of the IEC 1248-1 (QC 260000) capability approval procedure. It is intended for use by the following originators: a) a customer wishing to procure inductors that are within the scope of the approved capability of his supplying compo
33、nent manufacturer, for example for detail specifi- cations (DS); b) a capability approved manufacturer of inductors wishing to prepare specifications for his own products which are within the scope of his capability approval. NOTES 1 The detail specification should take the form of the BDS shown in
34、clause 5, particularly in respect of the front page format and. in principle. in respect of the presentation of the inspection requirements. 2 Unless otherwise specified, all the tests shown in the BDC are taken from IEC 1007. Those shown lined concern operating characteristics of fundamental import
35、ance. and it is strongly recommended that these are selected by the specification writer for inclusion in the detail specification. The tests shown in plain type are listed for the convenience of the specification writer, and tests should be selected from them according to the particular application
36、 of the component. 3 The specification writer may specify tests and sampling levels different from, less than, or additional to those given in the BDS. Page 6 EN 61248-6 : 1997 3.1 General 3.1.1 these shall be fully specified in the detail specification. Where additional tests of a type not defined
37、or invoked in IEC 1007 are required, 3.1.2 by the addition of the notation “(D)“. Any tests considered as being destructive shall be so denoted in the test schedule NOTE - The use of this notation is not illustrated in the BDS. 3.1.3 Tests shall be grouped in the schedule according to the level of s
38、ampling required and, unless otherwise indicated (see 4.1 b), in the order of testing required. Where 1 O0 YO testing is not required, inspection levels and acceptable quality levels shall be selected from IEC 410. 3.1.4 The completed detail specification shall be allocated a component identity numb
39、er and issue status by the originator. NOTES 1 This number is chosen by the originator (manufacturer or customer) within his own system. It is thus not subject to any external rules or codification. 2 In the special case of a manufacturers detail specification for a standard catalogue item which the
40、 manu- facturer wishes to be listed in IEC QC 001004, the national committee will allocate an appropriate number from its register. 3.1.5 A number allocated by the component manufacturer shall be additionally included in the detail specification, comprising this specification number, his factory ide
41、ntification code letters, and a unique number within his registration system, for example OC 260500/PQR/1234. NOTE - After a detail specification has been allocated the manufacturers reference number in accordance with 3.1.5, it is to be considered a contractual part of the order. Copies of all such
42、 detail specifications are to be retained by the manufacturers chief inspector. 3.2 Ratings and characteristics 3.2.1 Ratings In the case of customer-originated detail specifications, customer and manufacturer agreement shall be obtained on the ratings to be ascribed to the component in the detail s
43、pecification. These ratings shall not exceed the scope of the manufacturers capability approval (see also 1.12 of IEC 1248-1). 3.2.2 Characteristics A customer shall prescribe in the detail specification any characteristic required for a component, 3.3 3.3.1 The detail specification shall incorporat
44、e a drawing of the inductors showing important features, such as those dimensions affecting interchangeability, restrictions on mounting, and marking requirements. Outline drawings and winding SCh8matiC diagram STD-BSI BS EN b12q-b-ENGL 1797 Lb2ilbbS Ob5b99 O77 Sll Page 7 EN 61248-6 : 1997 3.3.2 The
45、 detail specification shall incorporate a schematic diagram showing all windings, screens, taps and phasings, and giving termination identification. 4 Inspection requirements to be listed In the detall specification 4.1 Conformance inspection The detail specification shall incorporate the following
46、notes: a) sampling inspections shall be carried out in accordance with IEC 410, normal inspection; b) tests in a group may be carried out in any order, except where otherwise indicated (see 3.1.3); c) components submitted to any tests marked (D) may not be released under IEC 1248-1 capability approv
47、al (D = destructive); d) the values given for measurement limits are absolute values: measurement un- certainty is to be taken into account. 4.2 Design verification The tests to be detailed under this heading are those whicti the specification writer considers to be inappropriate to lot-by-lot relea
48、se, but appropriate to the verification of new and original designs. Accordingly, they are to be performed only when specifically so stated in the order, and the detail specification shall carry a statement to this effect. If design verification is required, the number of specimens and the requireme
49、nt that there shall be no failures shall be stated in the detail specification. NOTE - Two specimens should normally be provided, unless otherwise stated. 5 Detail specification The BDS which follows, when completed in accordance with clause 3, shall form the relevant detail specif cat ion. NOTE - The front page of the BDS has been based upon the need for a customers detail specification. Where a manufacturers detail specification is required, some changes will be necessary, but the basic format should be retained. STD*BSI BS EN bL248-b-ENGL
