On October 16, 2015, Suzhou Yunbai Environment passed all test items of the US UL testing agency and was awarded a product test certificate for Suzhou Yunbai. The product diameter in the certificate covers 5” to 8”. The UL test content complies with the UL103 standard, which is the highest grade and most stringent requirement for chimneys in the world. The maximum test temperature reaches 2100℉ (1150℃), and the maximum load of all components is 4 times the design value.
Before the certificate was issued, the US UL Testing Center assigned foreign engineers to conduct an on-site factory inspection of Suzhou Yunbai Environment Suzhou Park Headquarters, and conducted scientific and strict inspections and analyses on production site management, quality control documents, laboratories and factory self-inspections. After the factory inspection was completed, the foreign engineers gave Suzhou Yunbai a high degree of recognition while judging that all items passed at once.
The passing of the US UL product testing project is the result and reward of Yunbai Enterprise's unremitting efforts in research and development, continuous improvement, and concerted efforts of various departments. It is an affirmation of our company's years of efforts and a re-verification of the company's product policy of "professionalization, branding, and internationalization". After receiving this honor, all departments of our company should continue to work hard and create more achievements for the corporate goal - to become the world's chimney leader, and make unremitting efforts!
