What each document proves — and what it does not
A certificate is granted to named models under stated conditions, so the useful question is not whether a supplier holds one but what it covers and what it leaves open. The table below applies that test to our own documents. Use the same four columns on any supplier’s paperwork.
| Evidence | What it supports | What it does not prove on its own | Product-condition scope | Buyer check |
|---|---|---|---|---|
| UL 867 listing File E522667 |
Electrical safety and ozone limits for the listed models | Grease-removal efficiency · fire performance inside a duct · that any other model shares the listing | LK / SE 6K, 12K and 18K (230V/50Hz) — 3 of our 102 models | Match the model on your order against the file, not against the company name |
| CE (MD + EMC + LVD) FQC2602501 |
Conformity for the named series, valid to 2031-01-09 | Acceptance in the United States or Canada · performance of any kind | LK30–480, LK-E series, UV series | Confirm your series is named on the certificate body |
| RoHS 2.0 BKC25114877LC |
Restricted-substance compliance for the named series | Performance, safety or efficiency of any kind | LK, SE, HME, FMC, HPS, LK-E | Ask which product lines fall outside the scope |
| Third-party efficiency report ZY05W230298, CMA-accredited |
Grease removal measured at a stated airflow under a stated method — up to 97.6% for LK in-duct units | The same result at a different airflow · performance once the cells are loaded · odor reduction | LK series, at the tested condition | Request the report itself and read the test airflow before treating any figure as a performance basis |
This table answers what each document covers. It does not answer whether the equipment suits your kitchen; that depends on airflow, cooking process and duct layout.
Three layers of acceptance, and they are separate
Documents settle the first layer only. Passing one layer does not clear the next.
- Equipment evidence. A listing and a test report describe a model under stated conditions. Where a condition in your project differs from the tested one, ask for the difference to be stated in writing rather than assumed away.
- Site installation and interfaces. Duct route, access clearance for cell withdrawal, grease drainage, fan static margin and the fire protection downstream are decided on drawings. Put the unit on those drawings at design stage, so the downstream coverage is priced with the system rather than as a change order.
- Whole-system operation. What an installed system achieves in service depends on capture at the hood, the process actually run and the maintenance regime. No certificate settles this layer in advance, so agree at handover how it will be checked and on what schedule.
Where a local authority sets an emission or odor condition, that condition is assessed on your site by a qualified person. The documents above support that assessment; they do not replace it. For how these checks fold into a supplier shortlist, see our commercial kitchen ESP buying guide.
