Standardi ajalugu

IEC 60115-8:2023 is applicable to fixed surface mount resistors for use in electronic equipment. These resistors are typically described according to types (different geometric shapes) and styles (different dimensions) and product technology. These resistors have metallized terminations and are primarily intended to be mounted directly onto a circuit board.
The object of this document is to specify 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:
a) definitions of product technologies and product classification levels of the generic specification, IEC 60115-1:2020, have been adopted;
b) new style of transverse (RT) resistors has been added in 3.1.5 and 4.2.2 to cover resistors with wide terminals, which have become common in market;
c) recommended test boards in 5.2.2 have been revised to fit the demands from the market for higher rated dissipation in resistors;
d) test boards have been revised so that they can be set vertically instead of horizontally during specified tests to optimize the temperature rise stability, area and spacing inside the test chamber;
e) 'Periodic-pulse high-voltage overload test' of IEC 60115‑1:2020, 8.3 has been added to the default test method in 5.3.8, however, the legacy test 'periodic-pulse overload test' of IEC 60115‑1:2020, 8.4 is still maintained for historical products;
and more. Please see the foreword for the list of changes.
