Website →

V-Trust Lab (branded STQ Lab), the laboratory arm of V-Trust Inspection Service Group, is a consumer-product testing lab in Beijiao Town, Shunde District, Foshan, with group headquarters at the Canton Fair Tower in Pazhou, Guangzhou. Accredited by CNAS, CMA and the U.S. CPSC, the lab runs over 100,000 tests per year and is best known for food-contact-materials (FDA, EC 1935/2004, LFGB, DGCCRF), hazardous-substances (REACH, RoHS, POPs, PFAS, BPA), and toys/juvenile-products testing (CPSIA, CPC, ASTM F963, EN 71, California Prop 65). Within its electrical-products line it offers EMC, LVD, RED and FCC compliance testing to support market access in Europe, the US, China, Korea and Australia/New Zealand, targeting medical devices, consumer goods, automotive and industrial equipment. Note: V-Trust presents EMC only at directive level (EMC Directive 2014/30/EU) without an itemised test-item or standards scope, and is primarily a chemical/consumer-product lab that offers EMC as part of electrical-product compliance — likely subcontracting full-chamber emissions/immunity work. The EMC service types below reflect the standard EN framework for the directives V-Trust cites rather than a published in-house scope; founding year is not stated, and CNAS/CMA/CPSC fall outside the directory's accreditation enum.

Within this power-apparatus context XIHARI operates a dedicated EMC test laboratory and provides EMC equipment calibration, primarily supporting the EMC verification of smart electrical equipment and switchgear controls. Note: the EMC lab is shown on the site only as an image with no itemised scope, and XIHARI is primarily a high-voltage/short-circuit power-apparatus institute where EMC is one supporting laboratory; the EMC service list below is inferred from that role and mapped to the governing IEC 61000-4 / IEC 62271 standard families. XIHARI test reports are accepted in 30+ countries; the institute also operates branches in Changzhou, Shenyang, Henan, Qingdao and Xiamen.
