In response to market and consumer concerns about the quality and safety of face masks, STC has invested additional cutting-edge test facilities and actively sought national and international accreditations to provide faster, flexible and professional face mask testing services. We aim at supporting the local and overseas face mask production sectors in producing high-quality masks. STC becomes the first accredited laboratory by both China National Accreditation Service for Conformity Assessment (CNAS) and International Accreditation Service (IAS) to offer International Laboratory Accreditation Cooperation (ILAC) accredited face mask testing in Hong Kong.
STC provides comprehensive international standard tests such as: Australian AS 4381:2015, Chinese National YY0469-2011, YY/T0969-2013 and GB15979, European Union EN 14683: 2019+AC: 2019 and USA ASTM F2100-19 etc., to meet requirements of face mask export registrations in different countries.
