Editorial policy

The rules the desk holds itself to, stated publicly so readers can hold it to them too.

Numbers

No invented statistics. This site publishes no case studies and no thresholds of its own, because it has no clients and inspects no products. Any figure in a guide comes from an official source named at the foot of the guide, is attributed in the text, and carries its check date. Worked examples use round numbers and are labelled illustrations. If a claim cannot be sourced, it is written as a method to check, not as a fact to believe.

Evidence grading

Every guide's safety file card states an evidence level: official law or guidance, harmonised standard, official guidance, or file method. The grade describes how the advice is supported, and guides say plainly when the honest answer is to check the regulation or take professional advice for a specific product.

Dates

Published dates are real. A guide's evidence-check date moves only when the guide is genuinely re-read against its sources. Volatile material (law, standards, official guidance) is written as a dated snapshot.

Voice

The desk writes as a knowledgeable explainer, not as a practising consultant, test lab or regulator. It never claims compliance for any product, never presents an illustration as a measurement, and never describes itself with status words like "expert" or "leading".

Corrections

Errors are corrected in the guide and recorded on the corrections page with the date and the reason. Silent edits to factual claims do not happen here.
