IEC 60704-2-2:2009 provides the methods of determination of airborne acoustical noise emitted by electric fan heaters, designed for placing on the floor, table or counter,etc., or for wall mounting supplied from mains or from batteries. The main changes from the previous edition are as follows: provisions with regard to measurement uncertainty and standard deviation for declaration and verification have been included in the scope. This publication is to be read in conjunction with IEC 60704-1:2010.
Abstract
Overview
IEC 60704-2-2:2009 - Household and similar electrical appliances - Test code for the determination of airborne acoustical noise - Part 2-2: Particular requirements for fan heaters specifies how to measure airborne acoustical noise from electric fan heaters (floor-, table-, counter- or wall-mounted) supplied from mains or batteries. It is intended to be read in conjunction with IEC 60704-1 (general requirements). The 2009 edition adds explicit provisions for measurement uncertainty and standard deviations used for declaration and verification of noise values.
Key topics and technical requirements
- Scope and exclusions: applies to electric fan heaters; excludes electric storage room heaters, humidifiers, dehumidifiers, air cleaners and heaters for exclusive industrial use.
- Frequency range: sound power determination covers octave bands with centre frequencies from 63 Hz to 8 000 Hz (note: 63 Hz may be less influential on A-weighted levels).
- Measurement methods: supports direct, comparison and standard methods referenced to ISO 3743-1, ISO 3743-2 and ISO 3744; choose method based on source size and test environment.
- Test environment and mounting:
- Reverberation room or free-field over reflecting plane with a vertical reflecting plane (absorption
