Quality

Quality system and product certifications: ISO 9001, CE and cETLus

Certificate numbers, issuing bodies and validity dates are listed as text, so you can verify each one directly with the issuer.

How we manage quality

YBT has operated an ISO 9001:2015 quality management system certified by TÜV NORD Taiwan since June 2017; the current certificate cycle runs to June 2029. For gas appliances, market certification is obtained through an accredited test body before mass production begins, so the certificate exists when the first container ships rather than being chased afterwards. YBT’s own patio heaters hold CE certification under Regulation (EU) 2016/426 with Module D production surveillance by Intertek Italia, and a cETLus listing to CSA/ANSI Z83.26 for the North American market. Responsibility for a quality issue is settled by its cause: a defect caused in production is YBT’s to correct; a defect caused by the customer’s design is the customer’s. Certificate numbers, issuing bodies and validity dates are published below as text, and each certificate can be downloaded as a PDF so you can verify it directly with the issuing body.

Quality questions

Can we see your ISO certificate?
Yes. The TÜV NORD certificate (no. 66 100 172733) is linked above as a PDF, and its validity can be checked in the TÜV NORD certificate database using that number.
Which gas appliance certifications do you hold?
CE under Regulation (EU) 2016/426 for outdoor patio heaters and domestic flueless space heaters, with Module D production surveillance by Intertek Italia (Notified Body 2575), and a cETLus listing to CSA/ANSI Z83.26 and CSA 2.37 for gas-fired outdoor infrared patio heaters covering six models. For a new ODM product, testing for the target market is arranged with the same bodies before mass production.
Have you been audited by brand customers?
YBT passed a BSCI factory audit in 2012 as an OEM supplier to the German retail chain OBI. Customer-specific audits are accepted; contact us to schedule one.
How are quality issues and warranty claims handled?
By cause. If the defect arises in YBT’s production, YBT is responsible for correction. If the defect arises from the customer’s design, responsibility rests with the customer. This applies to both OEM production and YBT’s own product range.
