The work of preparing International Standards is normally carried out through IsO International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75%of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. ISO 12567-2 was prepared by Technical CommitteeISO/TC 163, Thermal performance and energy use in the builtenvironment,SubcommitteeSc1,Testandmeasurementmethods. IsO 12567 consists of the following parts, under the general title Thermal performance of windows and doors-Determinationofthermaltransmittancebyhotboxmethod: Part 1:Complete windows and doors Part 2:Roofwindowsand otherprojectingwindows. @ ISO 2005- All rights reserved onal Organization for Standardizatior Not for Resale ISO 12567-2:2005(E) Introduction This part of ISO12567 should be read togetherwith ISO 12567-1:2000 Thermalperformance ofwindows and These two parts were jointly developed by ISO and CEN.
