Practical guides: start with the question, not the standard
These are not standard summaries. They are working notes: clause numbers, acceptance criteria, worked examples, the evidence chain an assessor actually traces, and the mistakes that show up on real shop floors. Every guide ends with one real tool or report you can use immediately.
Every guide is a full article: short answer, clause references, worked examples, practical pitfalls and FAQ. A complete Chinese edition of each guide is available from the Chinese index.

Guides are compiled from publicly available standard and accreditation-body documents (references, titles and paraphrased intent only — no verbatim text), for preparation and study only; they are not certification or accreditation decisions, nor legal advice. The current laboratory standard is ISO/IEC 17025:2017 (no 2025 edition); Global ACI replaced IAF and ILAC on 1 January 2026; IATF 16949 is published by the IATF and is not an ISO standard.
