Method of measurement of current noise generated in fixed resistors
SIST EN 60195:2016

IEC 60195:2016 specifies a method of measurement and associated test conditions to assess the "noisiness", or magnitude of current noise, generated in fixed resistors of any given type. The method applies to all classes of fixed resistors. The aim is to provide comparable results for the determination of the suitability of resistors for use in electronic circuits having critical noise requirements. This edition includes the following significant technical changes with respect to the previous edition: - harmonization of the allocation of isolation resistors RM in the recommended operating conditions given in Table 2; - correction of erroneous numeric values of the contribution of system noise, f(T - S) in Table 3; - addition of advice on the prescription of requirements in a relevant component specification; - addition of a set of recommended measuring conditions for specimens with a rated dissipation of less than 100 mW; - complete editorial revision.

Fixed resistors for use in electronic equipment - Part 8-1: Blank detail specification: Fixed surface mount (SMD) low power film resistors for general electronic equipment, classification level G
SIST EN 60115-8-1:2015

IEC 60115-8-1:2014 is applicable to the drafting of detail specifications for fixed surface mount (SMD) low-power film resistors in rectangular chip shape (styles RR) or in cylindrical MELF shape (styles RC) classified to level G, which is defined in IEC 60115-8:2009, 1.5 for general electronic equipment, typically operated under benign or moderate environmental conditions, where the major requirement is function. Examples for level G include consumer products and telecommunication user terminals. This edition includes the following significant technical changes with respect to the previous edition: - It includes minor revisions related to tables, figures and references. - Dedication to resistors of product classification level G, which is for general electronic equipment, typically operated under benign or moderate environmental conditions, like e.g. consumer products, or telecommunication user terminals. - Implementation of the zero defect policy with the application of the single assessment level EZ in all test schedules. - Substitution of the temperature coefficient of resistance (TCR), specified over the full defined temperature range, for the inferior and less significant temperature characteristic. - Adition of a test for the immunity against electrostatic discharge. - Implementation of the concept of stability classes with coordinated requirements to the performance at all prescribed tests. - Addition of information relevant for the component user in his assembly process. - Addition of an Annex providing special provisions for 0 resistors (jumpers), which may be part of a range of products covered by a detail specification derived from this blank detail specification.

IEC 60115-1: 2008(E) is a generic specification and is applicable to fixed resistors for use in electronic equipment. It establishes standard terms, inspection procedures and methods of test for use in sectional and detail specifications of electronic components for quality assessment or any other purpose. This fourth edition cancels and replaces the third edition issued in 1999 and Amendment 1 (2001). It constitutes a technical revision. It contains the following significant technical changes with respect to the previous edition: a) implementation of Annex Q which replaces Clause 3; b) addition of new tests procedures in 4.34 through 4.38; c) removal of the property 'temperature characteristics' from 4.8; d) introduction of a new system of test severities for the shear test in 4.32; e) introduction of new bias voltages for the damp heat steady-state test in 4.24; f) furthermore, this fourth edition cancels and replaces the third edition published in 1999 and constitutes minor revisions related to tables, figures and references.

Fixed resistors for use in electronic equipment - Part 2: Sectional specification: Leaded fixed low power film resistors
SIST EN 60115-2:2015

IEC 60115-2:2014 is applicable to leaded fixed low-power film resistors for use in electronic equipment. These resistors are typically described according to types (different geometric shapes) and styles (different dimensions) and product technology. The resistive element of these resistors is typically protected by a conformal lacquer coating. These resistors have wire terminations and are primarily intended to be mounted on a circuit board in through-hole technique. The object of this standard is to prescribe preferred ratings and characteristics and to select from IEC 60115-1, the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of resistor. This edition includes the following significant technical changes with respect to the previous edition: - it includes test conditions and requirements for lead-free soldering and assessment procedures meeting the requirements of a "zero defect" approach; - it introduces a product classification based on application requirements; - it includes an extension of the list of styles and dimensions; - it includes the use of an extended scope of stability class definitions; - it includes the extension of the lists of preferred values of ratings; - it includes test conditions and requirements for lead-free soldering, for periodic overload and for resistance to electrostatic discharge (ESD); - it includes a new set of severities for a shear test; - it includes definitions for a test board; - it includes the replacement of assessment level E and possible others by the sole assessment level EZ, meeting the requirements of a "zero defect" approach; - it includes an extended endurance test, a flammability test, a temperature rise test, vibration tests, an extended rapid change of temperature test, and a single pulse high-voltage overload test; - it includes requirements applicable to 0-ohm resistors (jumpers); - it includes recommendations for the denomination, description, packaging and quality assessment of radial formed styles; - it includes prescriptions for endurance testing at room temperature, supplementary to the rulings of IEC 60115-1.
