BS EN 16240:2013EN 16240:2013 (E) 5 Introduction This document describes the requirements for light transmitting flat solid PC sheets for internal and external use in walls, roofs a
23、nd ceilings. It is applicable to the sheets for the delivery only. Reference should be made to national regulations and manufacturer literature for requirements concerning the design, storage and fundamental guidance for installation of sheets, including all safety aspects. The standards and guideli
24、ne addressing light transmitting flat solid PC sheets for building applications are the following: EN 1873, Prefabricated accessories for roofing Individual roof lights of plastics Product specification and test methods (harmonized standard) EN 14963, Roof coverings Continuous rooflights of plastics
25、 with or without upstands Classification, requirements and test methods (harmonized standard) EOTA ETA-Guideline 010, Self supporting translucent roof kits The flat solid PC sheets that satisfy the requirements of this document are suitable for use as components in accordance with EN 1873, EN 14963
26、or ETAG 010. BS EN 16240:2013EN 16240:2013 (E) 6 1 Scope This European Standard specifies the requirements for light transmitting flat solid polycarbonate (PC) sheets for internal and external use in walls, roofs and ceilings. This European Standard applies to light transmitting flat extruded solid
27、PC sheets of minimum thickness 2 mm, without or with uniform functional layers (e.g. coating, co-extruded layer) made from PC-based or other materials. It also specifies the test methods needed for the evaluation of conformity and marking of the sheets. 2 Normative references The following documents
