scope:

This document specifies the requirements and test methods for factory-made cellular glass products which are used for thermal insulation of building equipment and industrial installations, with an operating temperature range of approximately -265 °C to +430 °C. The products are manufactured in the form of slabs, faced or unfaced boards, pipe sections, segments and prefabricated ware. Products with a declared thermal conductivity greater than 0,065 W/(m·K) at 10 °C are not covered by this standard. This documents does not cover products for the insulation of the building structure. This document describes product characteristics and test methods, designation code, marking and labelling. This document does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. Specific requirements, such as type, dimensions and forms, regulatory compliances and inspection requirements or certification requirements shall be agreed upon between the purchaser and the supplier and stated in the purchase contract. NOTE - Below an operating temperature of -50 °C, special tests regarding the suitability of the product in the intended application are advised (e.g. liquefaction of oxygen). Manufacturer's advice should be needed in all cases.
