It is identical with
10、IEC Publication 115-5 QC 400300 “Fixed resistors for use in electronic equipment. Part 5: Sectional specification: Fixed precision resistors”, published in 1982 by the International Electrotechnical Commission (IEC). This standard is a harmonized specification within the IECQ system of quality asses
11、sment for electronic components. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is dr
12、awn especially to the following. For the purposes of this Part of BS 9940 1.1 and 1.2 should be regarded as constituting the scope of the standard. Cross references The British Standard harmonized with QC 001001 and QC 001002 is BS 9000 “General requirements for a system for electronic components of
13、 assessed quality” Part 1:1981 “Specification of basic rules and procedures.” A British Standard does not purport to include all the necessary provisions of a contract.

General 1 General 1.1 Scope This standard applies to fixed precision resistors f
18、or use in electronic equipment. 1.2 Object The object of this standard is to prescribe preferred ratings and characteristics and to select from IEC Publication 115-1 (1982), the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for th
19、is type of resistor. Test severities and requirements prescribed in detail specifications referring to this sectional specification shall be of equal or higher performance level, because lower performance levels are not permitted. 1.3 Related documents IEC publications NOTEThe above references apply
20、 to the current editions except for IEC Publication 68, for which the referenced edition in the applicable test clauses of the generic specification shall be used. 1.4 Information to be given in a detail specification Detail specifications shall be derived from the relevant blank detail specificatio
21、n. Detail specifications shall not specify requirements inferior to those of the generic, sectional or blank detail specification. When more severe requirements are included, they shall be listed in Sub-clause 1.8 of the detail specification and indicated in the test schedules, for example by an ast
22、erisk. NOTEThe information given in the Sub-clauses 1.4.1 and 1.4.3 may, 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 those given in the appropriate clause of this sectiona
23、l specification. 1.4.1 Outline drawing and dimensions There shall be an illustration of the resistor as an aid to easy recognition and for comparison of the resistor with others. Dimensions and their associated tolerances, which affect interchangeability and mounting, shall be given in the detail sp
24、ecification. All dimensions shall preferably be stated in millimetres, however when the original dimensions are given in inches, the converted metric dimensions in millimetres shall be added. Normally the numerical values shall be given for the length of the body, the width and height of the body an
