Home / Certifications
A certificate that names one model does not automatically cover another model in the same family, and plating changes can void a listing. This page explains which standard applies to what, and how to check the document you are handed.
Our position
We do not display certification marks on this website. Instead, for the model you are quoting we send the certificate itself, with the model number visible, and we state plainly when a model is not yet certified.
If your customer needs cUPC, say so in the first email. We check the model against the document we actually hold before quoting, so the price you receive already includes the right product — not the cheapest one that happens to be nearby.
Routes
These are the routes that matter commercially. The certificate, not this table, is the authoritative document — always check the model number printed on it.
| Product | United States / Canada | European Union / UK |
|---|---|---|
| Handshowers and shower sets | cUPC to ASME A112.18.1 / CSA B125.1, with NSF/ANSI 61 and 372 for materials in contact with drinking water | EN 1112 (shower outlets); EN 817 or EN 1111 where a valve or thermostatic element is part of the set |
| Shower hoses | ASME A112.18.6 / CSA B125.6 | EN 1113 |
| Thermostatic and pressure-balance valves | ASSE 1016 / ASME A112.1016 | EN 1111 (thermostatic); EN 817 (mechanical mixing) |
| Surface finish | Salt-spray performance stated per finish on the technical sheet | Same — plus member-state requirements where they exist |
EU member-state material approvals sit on top of the EN standards, not instead of them: WRAS in the United Kingdom, KTW in Germany, ACS in France, KIWA in the Netherlands. There is no single “EU bathroom certificate” — a supplier claiming one is either simplifying or guessing.
Flow rate
| Market | Maximum flow rate |
|---|---|
| United States — federal | 2.5 gpm at 80 psi |
| United States — WaterSense label | 2.0 gpm |
| California (Title 20) | 1.8 gpm |
| European Union | Set per member state and per product class; stated on the technical sheet for the model quoted |
A 2.5 gpm head sold into California is a compliance problem for the importer, not the factory. We ask for the destination state before quoting for that reason.
How to check a document
cUPC listings come from IAPMO. An in-house “certificate of conformity” printed by the factory is not a listing, however official the layout looks.
Find the model column. If your model is not there, the document does not cover it — even if the product photo looks identical.
Plating and finish changes can affect a listing. Matte black and chrome are not always certified under the same file.
Look for an expiry or a listing date. A superseded standard number means the document is historical, not evidence.
Current status
Updated as documents are received from the manufacturer. Ask for your model — we send the actual certificate PDF.
| Product line | Document status |
|---|---|
| Shower hoses | Test reports and certification documents issued per model on request |
| Handshowers | Test reports and certification documents issued per model on request |
| Shower sets (rail kits) | Component certificates issued per model and per finish on request |
| OEM / private label models | Same documents apply where the model is unchanged; a new mould requires new testing |
Ask for the file
If a model has no certificate yet, we will say so before you commit to anything.
