Quality & certifications

A certificate has a scope. A logo does not.

CE and FCC marks apply to a model and a market, not to a factory in general. ISO certificates apply to a management system and a site. We keep those scopes visible so a buyer can check what is actually covered.

Certification register

What each document covers.

The register below states the type of document and its scope. Verified copies, including certificate numbers and validity dates, are shared on request and matched to the model being purchased.

DocumentTypeScopeHow it is provided
ISO 9001 Management system certificate Quality management at the manufacturing site Verified copy on request; site and validity stated
ISO 14001 Management system certificate Environmental management at the manufacturing site Verified copy on request; site and validity stated
CE Declaration / test reports Specific model, directive and market Declaration and supporting reports for the purchased model
FCC Equipment authorization Specific model and radio configuration Grant or test report for the purchased model
UKCA Declaration / test reports Specific model and UK market Declaration and supporting reports for the purchased model
RoHS Compliance declaration Materials in the shipped bill of materials Declaration plus material evidence on request
BQB Bluetooth qualification Bluetooth subsystem and declared design Qualification record for the radio design used
KCC / TELEC Radio compliance Specific model and national market Certificate for the purchased model and market

If a certificate does not exist for the exact model and market you need, it does not appear on a quotation as if it did. Certification is scoped and priced as a program activity.:

Quality system

Four controls that keep a program consistent.

Certification says the system is defined. These are the parts that affect a shipped remote.

01 / Documents

Revision control

Drawings, BOM, firmware and test specifications carry revisions. A production order references exact revisions, so a change cannot slip in without a record.

02 / Incoming

Material verification

Critical components and cosmetic parts are checked against the approved sample per lot. A substitute part is a change, not a purchasing decision.

03 / Production

Functional test

Every unit is tested on a fixture against the released firmware. Test results are recorded per unit and summarized per lot.

04 / Feedback

Corrective action

Field or pilot failures are classified by cause and fed back into the design, fixture or work instruction. The record shows the fix, not only the complaint.

Reliability testing

61 tests, five families.

This is the full list from our reliability laboratory, not a selection from it. A program runs the subset its product, market and battery type require; the report names what ran and what did not apply.

How the list is used

Selected per product, not copied across

An IR remote and a BLE voice remote do not run the same 61 tests. The program test plan marks each item as required, optional or not applicable, and the report keeps that marking.

Items marked † apply only to products with a rechargeable battery.

Laboratory

Verification

How to check a certificate in five minutes.

A buyer should not have to trust a PDF pasted into a brochure. These are the checks we expect, and the ones we make on our own documents.

Check 01

Match the model

The certificate or grant should name the model, radio configuration and variant you are buying. A sibling model is not the same scope.

Check 02

Match the market

CE, UKCA, FCC, KCC and TELEC are not interchangeable. The document should match the country the product ships to.

Check 03

Check the issuer and date

Look up the issuing body and the certificate number. Confirm the validity date and whether the scope covers the manufacturing site.

Check 04

Ask for the test report

A declaration without supporting reports is a statement of intent. The report shows what was measured and on which sample.

Questions

Quality & certification FAQ

Can you put our brand on the certificate?
The applicant can usually be the brand owner, which puts the certificate in your name. That is decided before testing starts, because changing the applicant afterward can require a new application.
Does a new color or logo require recertification?
Often not for radio, but the change must be checked against the existing reports. A new material near the antenna or a metal logo can affect RF. We assess the change and re-test only what is affected, with the decision recorded.
Who owns the test reports?
Ownership and access are set in the development agreement. Typically the client receives copies for the models they paid to certify. We retain the right to reference the platform for other programs only where the agreement allows it.
Do you certify the factory or the product?
Both can exist, but they answer different questions. ISO 9001/14001 cover the management system and site. CE, FCC and similar marks cover a product model. A factory certificate does not make a product compliant, and a product certificate does not audit the factory.

Document request

Ask for the document, not the logo.

Tell us the model and the market. We will send the certificate, the report and the scope — or say plainly that it does not exist yet.
