IEC 60115-1:2008 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 standard cancels and replaces IEC 61045-1 (1991), IEC 61045-2 (1991) and IEC 61045-2-1 (1991). This edition 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.
