UL Testing in China for a Turkish Door Manufacturer

A Turkish manufacturer needed its door assembly tested to UL in a Chinese laboratory. Three things stood in the way: getting the sample into the country, building the wall to both their drawings and the UL requirements, and communicating with the lab.

The Challenge

A Turkish door manufacturer had a product ready for the North American market and a laboratory in China prepared to test it. Between those two points sat three problems nobody had solved. The sample had to be shipped into China and cleared through customs. The supporting wall had to satisfy their own drawings and the UL requirements at the same time, which are rarely the same document. And every technical question had to cross a language barrier twice: from Turkish to English, then from English to the Chinese laboratory engineers.

What We Did

We took responsibility for the whole chain rather than handing the client a list of contacts. On logistics, we handled the import from start to finish: documentation, customs declaration and clearance, and delivery to the laboratory door. On the technical side, we ran drawing review sessions between the client's engineers and our construction team, reconciling their design intent with what the UL standard actually requires of the specimen — framing, board layout, fixings and thermocouple positions. We then supplied installers who had built this type of specimen before and put the wall up on site to those agreed details. Throughout, we acted as the technical interpreter, turning questions in both directions into drawings, decisions and records.

The Result

The wall passed inspection on the first attempt and the laboratory issued the UL test report. The client had budgeted for a second submission; it was not needed. What proved more valuable for later projects was that the route became repeatable: factory in Turkey, laboratory in China, one party accountable for the whole chain, from shipping documents to a signed report.
