IEC 60675-3:2020 applies to electric direct-acting room heaters. This document defines performance characteristics related to the radiant effect and specifies methods for measuring the radiation efficiency for the information of users. This document is used to measure the radiation efficiency of direct-acting room heaters. This International Standard is to be used in conjunction with IEC 60675:1994, IEC 60675:1994\/AMD1:1998 and IEC 60675:1994\/AMD2:2018.<\/p>\n
