No. A model name or ECE 22.06 marking does not let a buyer assume that every catalog size is within one approval. Compare the approval communication and markings with the exact offered sizes and their shell, energy-absorbing-liner, visor and helmet-type configurations, and hold any size that cannot be mapped without inference.
Does an ECE 22.06 approval automatically cover every offered helmet size?
Separate the sales size run from the approval scope
A supplier's catalog may group several sizes under one model family, while the approval material defines the type and details that were reviewed under UN Regulation No. 22. Put the requested assortment beside the approval communication instead of treating the broadest advertised range as approved by default.
Create one row for each offered size and record the size label, circumference range, shell construction or group, energy-absorbing-liner reference, visor and helmet-type designation. Leave an evidence cell blank when the record does not resolve it; do not complete the matrix from marketing copy.
Read the approval communication and its extensions
Request the complete approval communication, not only the approval mark or first page. Identify the approval holder, helmet type or model designation, approval number, applicable series and supplement information, covered size details, drawings or photographs and any extension pages relevant to the offered production revision.
Check dates and extension identifiers in sequence. A later catalog addition, larger shell, different visor or changed lower-face-cover configuration should trigger a written scope question rather than an assumption that the earlier document automatically follows the product name.
Map construction differences across the size run
Ask the approval holder or responsible manufacturer to show how each size maps to the construction described in the approval record. Pay particular attention at size boundaries where the shell, energy-absorbing liner, retention layout or other approved characteristics change.
This article does not prescribe which sizes must be tested or claim that every size requires a separate approval. The purchasing control is narrower: every offered size needs evidence that the responsible party can map to the applicable approval scope for the exact configuration.
Compare physical markings and representative samples
Obtain representative samples from the intended range, including sizes on either side of a construction change. Record the approval marking, size label, type designation, component references and sample revision, then compare those identifiers with the reviewed communication.
Do not use one photographed label to release every carton. Define preshipment checks that sample size labels and markings across the order and compare them with the approved size-color matrix and production specification.
Keep fit planning and approval planning linked but distinct
The distributor sizing guide helps plan head-circumference data, head-shape notes, liner service parts and retail fitting content. Those activities do not establish ECE approval coverage, just as an approval record does not guarantee that an individual customer will fit the helmet.
Link both records in the purchase file: one matrix for approval scope and one for assortment and fit guidance. Release a size only when its commercial availability, product data, approval mapping, sample and labels are all resolved.
| Offered size | Construction reference | Approval evidence | Sample and marking check | Release status |
|---|---|---|---|---|
| First size in range | Record shell and liner reference | Locate in the complete communication | Review physical size and approval markings | Release only when matched |
| Size at construction boundary | Record the changed shell or liner group | Ask for written mapping or applicable extension | Sample both sides of the boundary | Hold if change is unexplained |
| Extended size | Record all configuration differences | Confirm that the offered size is within the applicable scope | Review the exact extended-size sample | Do not infer from smaller sizes |
Risk notes
- Do not equate a model-family name with approval of every catalog size.
- Do not assume that similar external appearance proves identical approved construction.
- Do not turn a size-chart fit decision into a certification claim.
Factory checks
- Which page and field of the approval material maps each quoted size to the approved type?
- Where do shell, energy-absorbing-liner, visor or helmet-type configurations change across the size run?
- Which representative sizes and markings will be available for buyer sample and preshipment review?
RFQ checklist
- Exact approval holder, approval number and helmet type designation
- Complete approval communication including relevant extension pages
- Requested quantity by model, size and color
- Size-to-shell and energy-absorbing-liner construction matrix
- Visor, retention and modular-configuration references by size
- Representative sample plan at each construction boundary
- Named party responsible for resolving unmatched sizes
