Glass in building. Determination of thermal transmittance (U value). Calculation method Ingestion-build-146508 The reference threaded length b

The reference threaded length b has been increased to 3d for partially threaded screws m14 to M20 so that these screws can be tensile tested by iso 3506-1 (b ≥ 3d is required to tensile test screws with reduced loadability)

Glass in building. Determination of thermal transmittance (U value). Calculation method Ingestion-build-146508 The reference threaded length b1 Scope This European Standard specifies a calculation method to determine the thermal transmittance of glazing with flat and parallel surfaces. This European Standard applies to uncoated glass (including glass with structured surfaces, e. g. patterned glass), coated glass and materials not transparent in the far infrared which is the case for soda lime glass products, borosilicate glass and glass ceramic. It applies also to multiple glazing
