Layouts for Standard - Part 2: Standard for Chemical Analysis

---

It is recommended that standards for methods of chemical analysis are drawn up in accordance with Part 3 of the ISO/IEC Directives for the technical work of ISO, which gives general guidance, and using the layout of which details are given on the following pages.
It should always be remembered, in making use of this layout, that it is for guidance only. It should be adapted to suit any special requirements. There may be no need for all the subdivisions provided: those not required should be disregarded.
With the object of helping to solve problems of drafting and layout which arise in drawing up standards for methods of chemical analysis, ISO/TC 47 has established a series of standard layouts:
— layout for a standard method of chemical analysis, with notes on its application (ISO 78-2);
— standard layouts for instrumental analyses, with notes on their application (ISO 78-3 and ISO 78-4).
A standard for a chemical product should form a consistent whole. In addition to specifying the characteristics required of the product, it should state how to determine these characteristics. A standard method of chemical analysis (test method) may be incorporated in the text of a standard for a chemical product. Test methods may be presented as separate clauses, as annexes or as separate parts. However, a test method will normally be issued as a separate standard if it is likely to be referred to in a number of other standards. This will shorten the text of the standard for the chemical product; and, if a general method of chemical analysis applicable to the product exists, the standard for the product may merely refer to it.
The adoption of a standard form of layout and drafting ensures:
— that no important point is overlooked in the preparation of the standard;
— that the various items of information to be included in the standard are always given in the same order;
— that any desired clause may be found rapidly, whatever the origin or scope of the standard (this is particularly important if part of the text is being translated or two texts are being compared);
— simplification, rationalization and standardization of methods, reagents and equipment used in test laboratories;
— that each International Standard or other international document prepared in this field is drafted in terms which are as clear as possible.
