With the MSTYR15 project now examining the correlation between claimed and actual EU tyre label performance, it is more important than ever for manufacturers to utilise test equipment they can trust to deliver reliable results. Hangzhou Zhongce Rubber Co., Ltd (ZC Rubber) reports that the machinery it uses to test rolling resistance was recently inspected by TÜV SÜD, and was certified as highly accurate.
According to the manufacturer of the Westlake and Goodride tyre brands, TÜV SÜD evaluated the ZC Rubber rolling resistance equipment against the requirements laid down by ECE R117; the tests delivered a Pearson product-moment correlation coefficient of 0.9955, thereby verifying the equipment’s high level of precision and stability. The tyre maker adds that, pursuant to relevant regulations, the TÜV SÜD test results have also been accepted by Brazil’s Ministry of Development, Industry and Foreign Trade (Inmetro) for its label regulation 544/2012.
Following the tests, TÜV SÜD awarded ZC Rubber benchmarking certification that verifies its machinery’s performance in relation to EC 1235/2011; Michael Staude, general manager tyres and wheels at TÜV SÜD, presented the certification to ZC Rubber’s vice-president of production, Zhang Limin.
Zhang stated that ZC Rubber was pleased to gain further certification from TÜV SÜD. “Our company always commits to offer valuable, comfortable and green tyres for customers, and protects the environment as one of our social responsibilities.” He added that ZC Rubber will continue its long-standing cooperation with TÜV SÜD and work to continuously improve its research and development capabilities and the performance of its tyres.
