Keep the evidence tied to its scope
| Requirement | Evidence to request | Boundary |
|---|---|---|
| IP / NEMA enclosure rating | Test report for the assembled enclosure | A gasket alone does not establish a rating |
| Material properties | Nominated grade data and agreed tests | Family names are not batch acceptance results |
| Flame performance | Exact standard, grade, thickness and test scope | No blanket flame certification |
| REACH / RoHS request | Current declaration for the supplied material or part | Review substance scope and applicability |
| Dimensional conformity | Approved drawing and inspection record | Define revision, method and sampling |
Include the actual requirement
Send the standard edition, relevant clause and expected evidence. We review whether the selected production partner and nominated material can support the requested documentation. Do not assume certification from a product image or a material acronym.
Special and safety-related applications
Food contact, high-speed rotating brush seals and safety-critical functions require separate specialist review. Do not use these product families as a basis for an unvalidated safety claim.
