Use of acronyms and their explanations

Do not use acronyms in the main title of a document, except IEC

In documents, reports or similar documents [10 pages or less], use the acronym with explanation once, and then use the acronym alone from that point onwards

In long documents, such as brochures, white papers, etc., rewrite the explanation and the acronym once on each new part or section, because readers may only look at certain sections rather than the whole document from start to finish

In articles, use the explanation of the acronym once for each article

On web pages, use the explanation of the acronym once for each web page
