Overview
IEC 60675-3:2020 establishes methods for measuring the radiation efficiency of household electric direct-acting room heaters. Published by the International Electrotechnical Commission (IEC), this standard supplements general performance measurement methods by setting out specific requirements and definitions related to radiant heating. Its aim is to provide accurate and comparable performance data regarding the radiant effect of such heaters so that users and manufacturers have reliable information for product comparison, safety validation, and product development.
This standard is intended for use alongside previous documents in the IEC 60675 series, notably IEC 60675:1994 and its amendments, ensuring continuity and harmonization across measurement methods for electric heating appliances.
Key Topics
-
Scope and Purpose:
IEC 60675-3:2020 applies to electric direct-acting room heaters intended for household use. It specifically defines properties connected to radiant heating, focusing on measuring radiation efficiency.
-
Definitions and Performance Metrics:
The standard precisely defines key terms such as radiant factor, radiation efficiency, active radiant heating surface, rated power, emissivity, and nominal heat-up time. These definitions establish a common understanding for manufacturers, testing bodies, and regulators.
