Overview
IEC 60704-1:2010 is a key international standard published by the International Electrotechnical Commission (IEC) that specifies general requirements for testing airborne acoustical noise emitted by household and similar electrical appliances. This standard applies to electric appliances powered by mains or batteries and used in typical household environments or similar settings such as hotels, coffee houses, launderettes, and barber shops. The 2010 edition introduces important updates, including guidelines for test enclosures suitable for built-in appliances. It establishes a consistent test code vital for manufacturers, testing laboratories, and certification bodies to measure and evaluate appliance noise emissions accurately.
