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

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60115-8-1 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This second edition cancels and replaces the first edition, published in 1989 and constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– It includes minor revisions related to tables, figures and references.

– 6 – IEC 60115-8-1:2014 © IEC 2014

– 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 Ω resistors (jumpers), which may be
part of a range of products covered by a detail specification derived from this blank detail
specification.
The text of this standard is based on the following documents:
FDIS Report on voting
40/2297/FDIS 40/2313B/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until the
stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to
the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

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

0 Introduction
COMMENT This introduction is not intended to be copied into the drafted detail specification. Therefore it is
positioned prior to the conventional document structure and clause numbering range. It nevertheless contains
normative requirements to the drafted detail specification.
0.1 Scope of this blank detail specification
This part of IEC 60115-8 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.
Another part of IEC 60115-8 provides a separate blank detail specification for 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 P.
Other parts of IEC 60115-8 may be issued to provide blank detail specifications for the drafting
of detail specifications for surface mount resistors of other geometrical shapes, of other
technologies or of other classification levels.
0.2 Function of this blank detail specification
A blank detail specification is a supplementary document to the sectional specification and
contains requirements for style, layout and minimum contents of detail specifications. Detail
specifications not complying with these requirements shall not be considered as being in
accordance with IEC specifications nor shall they so be described.
The detail specification should contain a table of contents before the first page of the actual
specification.
In the preparation of the detail specification, the content of IEC 60118-8:2009, 1.4 shall be
taken into account. The detail specification should be written by using the preferred values
given in IEC 60115-8.
Units, graphical symbols and letter symbols should, whenever possible, be taken from those
prescribed by the following standards:
– IEC 60027-1, Letter symbols to be used in electrical technology – Part 1: General
– IEC 60617, Graphical symbols for diagrams
– ISO 80000 (all parts), Quantities and units
This blank detail specification uses for its purpose two different indications:
– NOTE For notes which give additional information intended to assist the
understanding or use of the resulting document and therefore they shall be

– 8 – IEC 60115-8-1:2014 © IEC 2014

copied as NOTE into the drafted detail specification. As outlined in the
