Drafting IEC publications

 

 

Title

Purpose or rationale

The title is a clear, concise description of the subject matter covered by the document. It is drafted so as to distinguish the subject matter from that of other documents, without going into unnecessary detail. Any necessary additional details are given in the scope.

 

Normative or informative?

The title is a normative element.

 

Mandatory, conditional or optional?

The title is a mandatory element.

 

Numbering and subdivision

The title is composed of separate elements, each as short as possible, proceeding from the general to the particular, for example:

  • an introductory element indicating the general field to which the document belongs (this can often be based on the title of the committee which prepared the document);
  • a main element indicating the principal subject treated within that general field;
  • a complementary element indicating the particular aspect of the principal subject or giving details that distinguish the document from other documents, or other parts of the same document.

No more than three elements shall be used. The main element shall always be included.

 

EXAMPLE 1 The introductory element is necessary to indicate the field of application.

Correct:

Raw optical glass

Grindability with diamond pellets

Test method and classification

Incorrect:

 

 

Grindability with diamond pellets

Test method and classification

 

The title of a part shall be composed in the same way. All the individual titles in a series of parts shall contain the same introductory element (if present) and main element, while the complementary element shall be different in each case in order to distinguish the parts from one another. The complementary element shall be preceded in each case by the designation "Part …:".

 

EXAMPLE 2

IEC 60947-1

Low-voltage switchgear and controlgear – Part 1: General rules

IEC 60947-2

Low-voltage switchgear and controlgear – Part 2: Circuit-breakers

 

When a document is divided into subparts (in the IEC), the parts within each subseries shall have the same subseries title.

 

EXAMPLE 3

IEC 61300-1

Fibre optic interconnecting devices and passive components – Basic test and measurement procedures – Part 1: General and guidance

IEC 61300-2-1

Fibre optic interconnecting devices and passive components – Basic test and measurement procedures – Part 2-1: Tests - Vibration (sinusoidal)

IEC 61300-2-2

Fibre optic interconnecting devices and passive components – Basic test and measurement procedures – Part 2-2: Tests - Mating durability

IEC 61300-3-1

Fibre optic interconnecting devices and passive components – Basic test and measurement procedures – Part 3-1: Examinations and measurements - Visual examination

IEC 61300-3-2

Fibre optic interconnecting devices and passive components – Basic test and measurement procedures – Part 3-2: Examination and measurements - Polarization dependent loss in a single-mode fibre optic device

 

 

Specific principles and rules

Avoidance of unintentional limitation of the scope

The title shall not contain details that could imply an unintentional limitation of the scope of the document.

Wording

The terminology used in the titles of documents shall be consistent.

 

For documents dealing with exclusively with terminology, the following expressions shall be used:

  • "Vocabulary" if both terms and definitions are included, or
  • "List of equivalent terms" if only equivalent terms in different languages are given.

For documents dealing with test methods, use the form

 

"Test method" or "Determination of …"

 

instead of expressions such as

 

"Method of testing", "Method for the determination of …", "Test code for the measurement of …" and "Test on …".

 

The type or nature of the document (e.g. International Standard, Technical Specification, Publicly Available Specification, Technical Report or Guide) shall not be indicated in the title.

EXAMPLE 1

Correct: Workplace air – Guidance for the measurement of respirable crystalline silica
Incorrect:  Workplace air – Technical specification for the measurement of respirable crystalline silica

 

Expressions such as "International test method for …", "Technical Report on …", etc. shall therefore not be used.

 

EXAMPLE 2

Correct: Test method on electromagnetic emissions – Part 1: […]

Incorrect:  International test method on electromagnetic emissions – Part 1: […]

 

The word "Guide" shall not be used in titles of documents developed by technical committees and subcommittees as it corresponds to a specific document type developed under the authority of the management boards (see the ISO/IEC Directives, Part 1). Titles using the words "Guidance" or "Guidelines" are acceptable (e.g. "ISO 26000, Guidance on social responsibility").
