IEC 60704-2-10:2024

Overview - IEC 60704-2-10:2024 (airborne acoustical noise for ovens & microwaves)

IEC 60704-2-10:2024 is the third edition of the particular requirements for measuring airborne acoustical noise from ranges, ovens, steam ovens, grills and microwave ovens for household and similar use. It is intended to be used together with IEC 60704-1:2021 (general test code). The standard defines test methods, measurement environments and data-recording requirements for laboratory measurement of sound pressure and sound power levels. Note: hobs and gas-powered appliances or appliance parts are excluded, and declaration of noise emission values is not within the scope.

Key topics and technical requirements

• Scope and exclusions: covers electric ranges, ovens, steam ovens, grills and microwave ovens; excludes hobs and gas-energy parts.
• Alignment and updates: technical revision aligned with IEC 60704-1:2021 and IEC 60350-1:2023 (definitions and settings); introduces measurement of steam function and revises test settings and parameters.
• Measurement methods: direct and comparison methods, with criteria for free-field, hard-walled and special reverberation test rooms.
• Acoustical environments: requirements for background noise, environmental conditions and criteria for adequacy of the test environment.
• Instrumentation and setup: microphone arrays, measurement surfaces, required instrumentation for acoustical and climatic data, and microphone placement (key positions illustrated).
• Operation and conditioning: appliance equipping, pre-conditioning, supply (electric/water), loading/operating modes and mounting/location for repeatable tests.
• Data processing: procedures for calculating sound pressure and A-weighted sound power levels, corrections for background noise and environment, and treatment of measurement uncertainties.
• Documentation: detailed lists of information to be recorded and reported, plus normative annexes (standard test table, test enclosure) and guidance for simple test rooms.

Practical applications and users

This standard is primarily used by:

• Product manufacturers (design validation, acoustic R&D)
• Test laboratories and acoustic measurement labs (type testing, reproducible measurement)
• Certification and conformity assessment bodies (verification of test methods)
• Acoustic consultants and compliance engineers (noise performance evaluation) Use cases include bench testing of ovens and microwaves, comparing noise levels between designs, validating steam-function noise, and establishing consistent laboratory procedures.
