This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.

What this guide covers

A helmet per use with the standard it must carry and what that standard actually tests: EN 1078 (bicycle), EN 1080 (children, chin release), EN 1077 class A/B (alpine), EN 12492 (mountaineering), NTA 8776 (speed pedelec), UN R22.06 (motorcycle). Item pages cover sizing by head circumference, the two-finger fit test, rotational-impact systems, the "replace after any impact" rule and the expiry claim, helmet law by country and second-hand risk — around 18 pages.

One focused section asks: "Bike helmet size by head circumference, with the fit test".

How to use it

Use Bicycle, ski and climbing helmets to understand the inputs, units and assumptions before relying on an output. A useful result should be reproducible from the named source rather than presented as an unexplained score.

The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.

Search vocabulary in four languages

Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.

Evidence and provenance

The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.

Source: UN ECE R22.06 full text (UNECE, free), CPSC 16 CFR 1203 (US CFR, public domain), EN/NTA standard numbers and scope abstracts from the CEN/EVS catalogue (free; text not reproduced), Virginia Tech helmet lab published ratings (linked and cited, not copied). · checked 2026-09-09

Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.

Scope and boundaries

This guide owns the explanatory layer for the topic. Personal decisions, diagnoses, legal determinations and live availability remain with the relevant professional or official service.
