Testing laboratory for glass and building products
- testing of physical and mechanical properties


Testing Laboratory No. 1139 is accredited by the Czech Institute for Accreditation for testing of  glass and building glass products and other materials, replacing glass. They conducted tests of the basic  soda lime silicate glass products (e.g. float glass, patterned, channel shaped and drawn glass) coated glass, bent glass, toughened safety glass and laminated glass, heat-strengthened glass, filmed glass, acid-etched glass etc. The lab tests also insulating glass units, mirrors, glass blocks and pavers, insulating mats and sheets from glass fibres, plastic sheets and other materials. Further tests glass containers and beverage glass.

Testing focuses primarily on the physical and mechanical properties. Cooperates with a number of other laboratories, to offer a much wider range of tests for glass.

In addition the laboratory deals in standardization activities - comments on draft standards EN and ISO standards, provides the translations into Czech language.
