Chinese certification for calibration gas supply


Linde Gases has been granted GBW certification by the Chinese State Bureau of Quality and Technical Supervision.

Linde Gases has been granted GBW certification by the Chinese State Bureau of Quality and Technical Supervision, approving the company’s production of gas reference materials from its plant in Suzhou, Jiangsu province in eastern China.

GBW is the official Chinese quality standards institute and their accreditation is a requirement for gas production facilities wishing to supply speciality calibration gas mixtures to both domestic and foreign-owned companies operating in China.

The plant will produce the company’s high purity gases and gas mixtures for the calibration of measurement instrumentation for environmental monitoring purposes, including the detection and control of combustion emissions for power generation, and, according to the company, will enable them to better support the growing emphasis being placed by China on tackling its CO2 emissions.

“There is increased importance on pollution control, sustainability and regulatory requirements by the Chinese government and this has substantially increased domestic demand for certified calibration gases,” said Zhu Min, special gases business manager, Linde China. “Linde’s Suzhou production facility will now make a valuable contribution to this.”

To achieve the GBW certification, Linde made a significant investment in plant operations through the appointment of both Chinese and expatriate scientists, engineers and other technical specialists, installation of best of breed laboratories and state-of-the-art gas filling facilities.

“Previously customers had limited options when sourcing measurement standards that met both Chinese and international standards.” said Stephen Harrison, global head of Specialty Gases and Specialty Equipment, Linde. “We are delighted that the Chinese authorities have formally recognized our efforts by awarding us the GBW certification.”
