Troll Electrical (Anhui) Co., Ltd. strictly follows international standards and domestic regulations to build a compliance management system covering the entire process of product design, production and testing.

Relying on advanced laboratory equipment, the company conducts more than 30 key tests such as electrical safety, energy efficiency performance, and electromagnetic compatibility in accordance with standards such as GB 4706 and IEC 60335 to ensure that the products pass China's 3C certification (covering indicators such as withstand voltage test ≤0.5mA leakage current, IPX4 waterproof level, etc.) and EU CE certification (meeting LVD low voltage directive, EMC electromagnetic compatibility standards). Through cooperation with international authoritative organizations such as TÜV SÜD, a three-level sampling mechanism from raw materials to finished products is established to achieve production consistency control. The certification system not only ensures that the products meet market access requirements, but also provides data support for product iteration through technical accumulation such as 1200 hours of durability testing and -40℃ extreme environment verification, forming a virtuous cycle of "compliance certification - quality optimization - technology upgrade".
