At present, the popular international safety certifications include DOT/SFI in the United States; TUV in Germany; VIA/JWL in Japan, etc. These certification bodies have slightly different concepts and evaluation criteria, but these three experiments are indispensable, namely: impact test, bending fatigue test and radial fatigue test. JWHEEL products have been certified by SEI and SEMA in the USA, VIA, JWL and JWL-T in Japan and TUV in Germany. Especially our impact resistance testing skill has exceeded the leading technical standards in Japan.
