SIST EN IEC 60115-8-10:2026 is an IEC blank detail specification for surface mount (SMD) low-power film resistors for assembly on circuit boards, classified to level G. It is the template used to draft product detail specifications for these resistors and to set the characteristics, tests, marking, packaging and quality assessment rules that such a detail specification should contain.

What does SIST EN IEC 60115-8-10:2026 specify?

SIST EN IEC 60115-8-10:2026 specifies how to draft detail specifications for SMD low-power film resistors classified to level G, based on the product classification levels in IEC 60115-1. It is a blank detail specification, so its main role is to define the structure and minimum content of a usable product specification for this resistor family.

The document is organized into clauses 1 to 9, followed by four annexes:

Annex	What it covers
Annex A	Symbols and abbreviated terms
Annex B	Reference for visual examination
Annex C	0 Ω resistors (jumpers)
Annex X	Cross-references to the prior revision of this specification

Clause 1 covers the scope, Clause 2 the normative references, Clause 3 the terms and definitions, Clauses 4 to 6 the characteristics, tests and performance requirements, Clause 7 marking, packaging and ordering information, Clause 8 additional information, and Clause 9 quality assessment procedures.

What are the key requirements of SIST EN IEC 60115-8-10:2026?

SIST EN IEC 60115-8-10:2026 is mainly a drafting framework, but it still fixes the technical content that a level G detail specification has to address. In practice, it tells the writer what has to be stated for dimensions, ratings, test conditions, acceptance criteria and quality assessment.

Product definition and application level

Clause 1 places the resistors in general electronic equipment and identifies level G as the classification level. That matters because the intended environment and duty level drive the ratings, test severities and qualification choices that follow.

Clause 1 also states that the detail specification is used to support quality assessment under the procedures of IEC 60115-1. For a manufacturer or buyer, that means the document is not just descriptive - it becomes the basis for approval, routine control and product acceptance.

Dimensions, ratings and resistance classes

Clause 4 and Figure 1 define the outline and dimensions, while Table 1 gives the style-specific sizes. Clause 4.2 also allows other shapes within the stated dimensional framework, so the document writer can describe the exact form of the resistor family being specified.

Clause 4.3 sets climatic categories, ratings and the derating curve. Table 2 identifies the climatic categories, Table 3 gives rated dissipation, limiting element voltage and insulation voltage, and Figure 2 shows how dissipation is reduced above the rated temperature of 70 °C. In practice, this tells the user what electrical and thermal limits the component family is built around.

Clause 4.4 links resistance range, tolerance and temperature coefficient of resistance to climatic category. Table 4 is the place where approved combinations are listed, and those combinations are used for qualification and quality conformance. This matters because it prevents a specification from accepting values that have not been qualified.

Test methods and severities

Clause 5 is the core test section. It covers resistance, temperature coefficient of resistance, temperature rise, endurance at 70 °C, endurance at the maximum temperature UCT, short-term overload, ESD, visual examination, gauging, detail dimensions, shear, substrate bending, rapid change of temperature, climatic sequence, damp heat, solderability with lead-free solder, solderability with SnPb solder, resistance to soldering heat, solvent resistance, insulation resistance, voltage proof and flammability.

Most tests are carried out with specimens mounted on a test board, unless the relevant subclause gives a special method. That matters because it reflects how these parts are used in real assemblies, not as loose components.

The solderability clauses are especially practical. Clause 5.17 gives a lead-free solderability test, and Clause 5.18 gives a lead-bearing SnPb solderability test. The document therefore supports both current and traditional soldering processes, which is important for mixed manufacturing environments.

Performance limits after testing

Clause 6 translates the test results into pass/fail requirements. Table 10 gives the limits for change of resistance after the various tests, and Table 11 gives the permitted resistance change due to temperature variation.

Clause 6.4 ties temperature rise to the maximum element temperature MET, which is also the basis for UCT. Clause 6.6 gives the solderability acceptance criterion in terms of solder coverage and visible defects, while Clause 6.7 sets insulation resistance requirements for insulated resistors. Clause 6.8 gives the flammability requirement based on the duration of burning after the needle flame is removed.

Marking, packaging and ordering information

Clause 7 sets the information that should appear on the component, the package and the order. For marked parts, the document points to IEC 60062 for resistance coding and allows either colour code or letter-and-numeral code depending on shape.

Clause 7.2 requires taped packaging in accordance with IEC 60286-3 and says the primary and proximity packaging are subject to visual examination. Clause 7.4 lists the minimum ordering information: detail specification number, style reference, nominal resistance, tolerance, temperature coefficient and any special variant. For procurement, that is the information needed to order the intended part unambiguously.

Quality assessment and 0 Ω resistors

Clause 9 requires 100% resistance testing during manufacture, followed by sampling reinspection to monitor outgoing quality level. It also sets the qualification approval and quality conformance inspection routes, with test schedules in Tables 12 and 13.

Annex C gives special rules for 0 Ω resistors. It replaces the normal climatic category and ratings tables with jumper-specific tables, uses residual resistance instead of normal resistance-stability limits, and removes the temperature coefficient and ESD tests from applicability. That is important when the same detail specification includes both normal resistors and jumpers.

What terms does SIST EN IEC 60115-8-10:2026 define?

• TCR - Temperature coefficient of resistance; it describes how resistance changes with temperature.
• LCT - Lower category temperature; it is the low end of the climatic category used in temperature-related tests.
• UCT - Upper category temperature; it is the high end of the climatic category used for test procedures.
• MET - Maximum element temperature; it is the temperature basis used to derive UCT and temperature rise limits.
• ESD - Electrostatic discharge; the document uses ESD testing to check sensitivity to static discharge.
• HBM - Human body model; the model used to apply the ESD voltage in the test.
• SPC - Statistical process control; the quality section refers to it as a way to control dimensional or process variation.
• ND - Non destructive; used in the test schedules to identify tests that do not destroy the specimen.

Who uses SIST EN IEC 60115-8-10:2026?

SIST EN IEC 60115-8-10:2026 is used by resistor manufacturers, product engineers, quality managers, test laboratories and certification bodies that prepare or assess detail specifications for SMD low-power film resistors. It is also relevant to procurement teams and buyers who need to identify the exact specification basis for a qualified resistor family.

The document is aimed at general electronic equipment applications, including consumer products and telecommunication user terminals. It is also relevant where quality assessment is done under systems such as IECQ.

What changed in SIST EN IEC 60115-8-10:2026 from the previous edition?

SIST EN IEC 60115-8-10:2026 replaces IEC 60115-8-1:2014 and is described as a technical revision. The significant technical changes stated in the document are:

• support for solderability testing with both lead-bearing SnPb solder and lead-free solder
• support for detailed visual acceptance criteria
• a visual examination requirement for the primary and proximity packaging
• allowance for specific visual acceptance criteria in addition to those in Annex B of IEC 60115-8:2023

Which standards are used with SIST EN IEC 60115-8-10:2026?

The document relies on several standards to define coding, dimensions, packaging, test methods and quality assessment:

• IEC 60115-1:2020 - provides the generic specification, core test methods, quality assessment procedures and the product classification level definitions
• IEC 60115-8:2023 - provides the sectional specification for fixed surface mount resistors and the detailed test and visual criteria referenced throughout
• IEC 60062:2019 - gives the marking codes for resistors and capacitors, used for resistance coding in marking
• IEC 60063 - provides preferred number series for resistor values
• IEC 60286-3 - gives packaging rules for surface mount components on continuous tapes
• IEC 61760-1 - provides the standard method for specifying surface mounting components and soldering process compatibility
• IEC 61193-2:2007 - provides sampling plan methods used for inspection and quality assessment

What does the SIST EN IEC 60115-8-10:2026 document contain?

SIST EN IEC 60115-8-10:2026 contains one outline figure, one derating curve, and a set of tables for styles and dimensions, climatic categories, ratings, resistance combinations, test severities and quality assessment schedules. It also contains detailed procedures for electrical, mechanical, climatic, solderability and flammability testing.

The document includes worked test schedules for qualification approval and for lot-by-lot and periodic quality conformance inspection. It also contains the symbols and abbreviations used in the specification, a visual examination annex, a dedicated annex for 0 Ω resistors, and a cross-reference annex to the prior revision.

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.

INTRODUCTION
0 Introduction to the template provided by this blank detail specification
COMMENT This introduction is not intended to be copied into the drafted detail specification. Therefore, it is
positioned in front of 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 surface mount
(SMD) low-power film resistors, classified to level G, based on the definition of the product
classification levels in IEC 60115-1:2020, 3.4.
Another part of IEC 60115-8 provides a separate blank detail specification for the drafting of
detail specifications for surface mount (SMD) low-power film resistors, classified to level P and
to level R.
Yet other parts of IEC 60115-8 may be issued to provide blank detail specifications for the
drafting of detail specifications for surface mount (SMD) resistors, 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 accepted as being in
accordance with IEC specifications nor shall they be described as such.
Detail specifications complying with the requirements of this blank detail specification are a
legitimate basis for the quality assessment of leaded fixed low-power film resistors under an
adequate quality assessment system, e.g. the IEC Quality Assessment System for Electronic
Components (IECQ System), whereas the plain blank detail specification is not a suitable basis.
The detail specification should contain a table of contents prior the first page of the actual
specification.
In the preparation of the detail specification, the content of IEC 60115-8:2023, 8.2 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 shall, 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
– IEC 80000 (all parts), Quantities and units
– ISO 80000 (all parts), Quantities and units
IEC 60115-8-10:2026 © IEC 2026
This blank detail specification uses for its purpose two different kinds of notes:
– NOTE For notes which give additional information intended to assist the
understanding or use of the resulting document and therefore shall be copied
as NOTE into the drafted detail specification. As outlined in the ISO/IEC
directives, these notes shall not contain any requirement, instruction,
recommendation or permission.
– COMMENT For editorial notes which are intended to aid and direct the specification
writer and therefore shall not be copied into the drafted detail specification.
In order to accomplish their function, editorial notes require the use of
instructions, recommendations and permissions addressed to the writer of
the detail specification.
0.3 Identification of the detail specification and the resistor
The first page of the detail specification should have a layout starting with a title block as
recommended on the following page.
The numbers in square brackets are editorial references, which are not intended to be copied
into the drafted detail specification, and which correspond to the following information on the
contents which shall be inserted in the indicated fields.

suitable for an entry in a register of approvals or in a catalogue of standards. It may duplicate
information given in fields [6] and [7] and in the textual scope in Clause 1.
[5] An outline drawing or illustration of the products. This entry should aid the easy recognition
of the specified resistors and, if possible, support the discrimination between similar
specifications. It may duplicate information given in Figure 1.
[6] Information on the typical construction of the resistors (where applicable), information of the
specified resistors being insulated or non-insulated (see IEC 60115-1:2020, 3.1.7), and
information on compatibility with a specific soldering process (if applicable, see 8.4). This
entry may duplicate information given in the textual scope in Clause 1.
[7] The classification level of the resistors covered by this detail specification, the level of
quality assessment (Assessment level EZ), and the general level of stability requirements
at performance tests (Stability class).
This information may duplicate information given in the textual scope in Clause 1.
[8] Optional field for table notes.
[9] Statement(s) about the availability of information on components qualified to this detail
specification, if applied within a full quality assessment system.
