Grg Metrology & Test Group Co., Ltd. is one of the larger independent test and calibration laboratories in China, founded in 1964 and headquartered in Guangzhou. The group is publicly listed on the Shenzhen Stock Exchange's SME board under stock code 002967 and operates more than sixty subsidiary companies across major economic regions of the country, employing several thousand staff. Recognitions from ABS, Bureau Veritas, DNV and Lloyd's Register support the laboratory's class-relevant scopes for the marine industry, and the laboratory portfolio is accredited under CNAS and other national accreditation schemes.
For shipping clients, the team's engineers handle inventory of hazardous materials and hazmat surveys, sampling and laboratory analysis of materials lists for new-build vessels and existing ships under the Hong Kong Convention and the EU Ship Recycling Regulation. Underwater inspection assignments are co-ordinated through the same channel, providing class-acceptable reports for in-water surveys, hull condition assessments and propeller polishing campaigns on vessels calling at Pearl River Delta ports.
The wider laboratory portfolio covers metrology and calibration, reliability and environmental testing, electromagnetic compatibility testing, noise and vibration measurement, failure analysis and component testing for the aviation, automotive, rail transit, electronics and shipbuilding industries. GRG's pressure vessel testing, materials testing and chemical analysis are performed for ship equipment manufacturers and shipyards across the region, supporting type-approval submissions to classification societies for items such as bridge electronics, engine-room consoles and switchboards. With laboratory space, calibration benches and field-mobile teams, the organisation is well placed to handle integrated compliance projects ranging from IHM Part I development through to EMC testing of newly installed bridge and engine-room equipment.
