IEC 60915:2006

Tue, 05 Nov 2024 19:09:15 +0000

IEC 60915:2006 contains preferred dimensions for shaft ends and bushes and for the mounting of single-hole, bush-mounted, shaft-operated variable capacitors, variable resistors and potentiometers. If other dimensions not listed in this standard have to be used, it is recommended to select them also from IEC 60390 and IEC 60620. This second edition cancels and replaces the first edition published in 1987 and constitutes a minor revision, related to tables, figures and references. This bilingual version, published in 2008-07, corresponds to the English version. The contents of the corrigendum of December 2008 have been included in this copy.

IEC 60717:2012

Tue, 05 Nov 2024 19:00:48 +0000

IEC 60717:2012 applies to capacitors and resistors with unidirectional wire terminations intended for use in electronic equipment. This standard provides a method for determination of the space required by capacitors and resistors with unidirectional wire terminations. NOTE: Instead of measuring the actual space, it may be sufficient to ensure that a component fits into the maximum space for which it is designed. This may be achieved by means of fixed gauges. The main technical changes with respect to the first edition are the following:
– employment of the millimetre-based grid, the preferred grid system given in IEC 60097,
– employment of SI units only, causing deletion of the imperial dimensions from Table 1,
– reduction of the tolerance on the chamfer depth in Figure 1, and
– introduction of requirements on information to be given in a relevant specification.

IEC 60477-2:2022

Tue, 05 Nov 2024 18:52:29 +0000

IEC 60477-2:2022 applies to resistors intended as laboratory AC resistors for use over a range of frequencies from DC up to a stated frequency which is not in excess of 1 MHz. Such resistors are hereinafter referred to as "AC resistors".
In addition to satisfying the requirements of IEC 60477-1, resistors satisfying the requirements of this document are designed to have a small variation of resistance and a small phase displacement over the stated frequency range.
IEC 60477-2:2022 cancels and replaces the first edition published in 1979, and Amendment 1:1997. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) extended the AC resistor frequency range to 1 MHz;
b) updated the terms and definitions according to IEC 60050 series;
c) added the definition of AC/DC difference of an AC resistor;
d) added the resistor classification according to the AC resistance or AC/DC difference index;
e) updated the classification according to the AC resistor construction;
f) updated the safety symbols and requirements according to IEC 60477-1;
g) added the three-element equivalent circuits of an AC resistor in Annex C;
h) added the annex on constructions of AC resistors.

IEC 60477-1:2022

Tue, 05 Nov 2024 18:52:26 +0000

IEC 60477-1:2022 applies to resistors intended for use as laboratory DC resistors (hereinafter referred to as "resistors") comprising standard resistors, single or multiple resistors of accuracy Classes 0,000 05 to 10 and single or multi-dial resistors of accuracy Classes 0,000 5 to 10.
This document does not apply to:
1) resistors which are intended for use solely as permanently mounted circuit components,
2) resistors used on alternating current or on pulsed current,
3) active resistors,
4) series resistors and shunts which are considered as accessories of electrical measuring instruments in the relevant IEC document (examples of these are as follows).
IEC 60477-1:2022 cancels and replaces the first edition of IEC 60477 published in 1974, and its Amendment 1:1997. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) extended the resistor accuracy classes;
b) deleted the resistor accuracy class expression in parts per million (ppm);
c) excluded the active resistor from the scope of this document;
d) updated the terms and definitions according to new IEC 60050 series;
e) changed the term "resistance decade" to "resistance dial" to cover the multi-dial resistors with other resistance step values;
f) updated the intrinsic error to intrinsic uncertainty according to IEC 60359;
g) added the limits of relative stability for resistors of classes 0,000 05 to 0,01;
h) added the requirements of high voltage resistors;
i) updated the safety symbols and requirements according to the new IEC 61010 series;
j) updated the insulation resistance requirements of resistors;
k) added the requirements of temperature coefficient;
l) updated the temperature requirements for transport and storage of resistors.

IEC 60440:2012

Tue, 05 Nov 2024 18:51:48 +0000

IEC 60440:2012 specifies a method of measurement and associated test conditions to assess the magnitude of non-linear distortion generated in a resistor. This method is applied if prescribed by a relevant component specification, or if agreed between a customer and a manufacturer. This International Standard cancels and replaces the Technical Report IEC/TR 60440, published in 1973. The major changes with regard to the Technical Report are:
– change of the principle parameter's term from "third harmonic attenuation" to "third harmonic ratio";
– addition of advice on the prescription of requirements in a relevant component specification;
– addition of a set of recommended measuring conditions for a specimen with a rated dissipation of less than 100 mW;
– a complete editorial revision.
