G-Tech Optoelectronics Corp. (GTOC) obtains CE certification for building glass after completing the EU Construction Products Regulation (CPR) certification process through TUV Rheinland. The certification was formally presented to Tony Chiu, Vice President of GTOC, by Max Lyou, Managing Director of TUV Rheinland Taiwan. The company's tempered glass, homogeneous glass, and laminated glass products must all pass safety and environmental testing to qualify for EU CPR certification. Its production and quality control system must meet all of the relevant requirements as well. GTOC is a leading provider of opto-electronics processing services, with an emphasis on very large ultra-thin glass and custom specifications involving special technologies and customer requirements. GTOC products are sold both locally and internationally. The CE certification standards for construction products were tightened in Europe with the introduction of the Construction Product Regulations 305/2011/EU (CPR), which took effect on July 1, 2013. The CPR replaces the previous Construction Product Directive 89/106/EEC (CPD). The CE mark must be displayed on all CPR-compliant construction products as assurance of their material performance and reliability. Only construction products with the CE mark are deemed to be safe, thereby allowing their free movement throughout the EU.
