Drafting IEC publications

 

 

Structure and subdivision
of an IEC publication

(The full requirements are described in the ISO/IEC Directives Part 2:2011, 5.2.2 and 5.2.3.)

 

The content of a document is divided into clauses and subclauses, which shall be numbered with Arabic numerals.

 

An important distinction shall be made between normative elements, which shall be complied with to claim conformity with the standard, and informative elements, which provide additional information. These are summarized in Table 2 of the ISO/IEC Directives Part 2:2011.

 

It is important to ensure that the clause and subclause structure is correct from an early stage so that updating cross-references within the document at a later stage does not lead to errors.

 

The presence of text between a clause/subclause and its first subdivision, i.e. a ”hanging paragraph”, is not allowed. This can be amended by adding a name and subclause number as illustrated:

 

avoiding hanging paragraphs

 

Do not subdivide clauses/subclauses if there is only a single subdivision:

A.3.1 Description

 

Parameter re-characterisation is a method of thermal uprating in which the part parameters are characterised over the target temperature range, using processes similar to those used by the device manufacturer for original device characterisation. If parameter re-characterisation is successful, the device may be used in applications in which the re-characterised parameters are acceptable.

 

A.4 Parameter re-characterisation process

 

Figure 4 shows a flow diagram of the parameter re-characterisation process.
