TS ISO 78-4

TS ISO 78-4 defines a document layout for standard analytical methods based on atomic absorption spectrometry and gives wording recommendations for presenting such standards. Its focus is not the analytical technique itself, but the consistent structure used when writing standards for atomic absorption-based methods.

How atomic absorption method standards are organised

Atomic absorption spectrometry is based on the absorption of light by free atoms at characteristic wavelengths. It is widely used for the determination of metals and trace elements. In standards that describe this technique, the arrangement of sections matters because it helps authors present the principle of the method, sample preparation, operating conditions, expression of results, and related procedural elements in a uniform way. This part provides a framework for that kind of technical presentation.

What this part covers

• A layout recommendation for standard analytical methods using atomic absorption spectrometry.
• Guidance on the presentation and wording of such standards.
• A structural framework for arranging the sections of method standards in a consistent technical order.
• Support for harmonised drafting of documents that describe practical analytical procedures.

This is a withdrawn edition, so it is mainly useful as a historical reference for how atomic absorption methods were standardised in document form. In general, layout standards in this field help different methods written around the same measurement principle remain more comparable, readable, and terminologically consistent.
