15、) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be repr

16、esented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to deve

17、lop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO

18、/IEC Directives, Part 2 (see www .iso .org/ directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

22、otal solar energy transmittance (TSET), solar factor and g-value are all used to describe the same quantity. Small differences might be caused by different reference conditions (e.g. differences in the reference solar spectrum). In this document, solar heat gain coefficient is used.This document is

23、designed to provide solar heat gain coefficient values by standardized measurement method and to enable a fair comparison of different products. It specifies standardized apparatus and criteria. The solar heat gain coefficient measuring apparatus applied in this document includes solar simulator, cl

24、imatic chamber, and metering box. Solar heat gain coefficient values of windows and doors with or without shading devices shall be determined more precisely by means of combination between calculation and measurement.This document does not deal with the centre of glazing solar heat gain coefficient

25、measurement. However, the centre of glazing solar heat gain coefficient can be measured by either this method or cooled plate method (see Reference 12).

40、me principle equations that are described as in ISO 15099:2003, Formula (14) and ISO 52022-3. Therefore, the determination of the solar heat gain coefficient of windows and doors involves two stages. The first stage is to measure the density of heat flow rate through the test specimen with irradianc

41、e (solar heat gain + thermal transmission). The second stage is to measure the density of heat flow rate through the test specimen without irradiance (thermal transmission).The net density of heat flow rate of incident radiation is determined by the radiometer in front of the test specimen during th

42、e first stage.The net density of heat flow rate of the solar heat gain is determined as the difference between the net density of heat flow rate measured in the first stage and the net density of heat flow rate due to thermal transmission, which is evaluated using the thermal transmittance measured

43、in the second stage.Since the measured solar heat gain coefficient, gm, of windows and doors is the ratio of the net density of heat flow rate of the solar heat gain to the net density of heat flow rate of incident radiation, it shall be calculated using Formula (1) with or without shading devices:g
