IEC 60704-2-13:2016

Overview

IEC 60704-2-13:2016 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the particular requirements for testing airborne acoustical noise emitted by household and similar electrical appliances, specifically range hoods and other cooking fume extractors. This third edition updates previous versions to cover new appliance types and configurations, including down-draft systems and built-in recirculation range hoods. The standard is intended to be used in conjunction with IEC 60704-1:2010, which provides general requirements for noise measurement.

This standard defines the methods and conditions for determining the noise levels produced under normal operating conditions at the highest normal use fan speed. It ensures reliable, repeatable, and comparable acoustical noise measurements for cooking ventilation appliances used in both residential and similar settings.

Key Topics

• Scope and Applicability

  • Applies to electrical range hoods and cooking fume extractors designed to filter or exhaust indoor air in household and similar environments.
  • Covers devices with external fans installed inside or outside the room, down-draft cooking fume extractors beside, behind, or under cooking surfaces, and built-in recirculation hoods with air outlet devices.

• Noise Measurement Methods

  • Specifies test codes based on ISO standards such as ISO 3743-1, ISO 3743-2, and ISO 3744 for measuring noise emissions.
  • Focus on airborne acoustical noise under realistic operating conditions and at typical maximum fan speed settings.
  • Provides guidance on instrumentation, measurement locations, and acoustical environments for testing.

• Technical Updates

  • Revised title and expanded scope to include all cooking fume extractors, not only range hoods.
  • Inclusion of exhaust pipe specifications for down-draft systems.
  • Requirements added for built-in recirculation air range hoods with air outlets.
  • Deletion of Annex AA for streamlined content.

• Measurement Uncertainty and Reporting

  • Defines standard deviations for repeatability (σ_r = 0.4 dB) and reproducibility (σ_R = 1.0 dB) of sound power levels.
  • Specifies standard deviations for declaration, verification, and production to ensure consistent noise emission values.
  • Outlines the required information to be recorded and reported during testing for transparency and certification purposes.

Practical Applications

• Product Development and Compliance Manufacturers of household cooking ventilation appliances use IEC 60704-2-13 to design and test products that meet international noise performance criteria, improving user comfort through quieter operation.

• Regulatory Testing and Certification The standard provides an accepted framework for certification bodies and testing laboratories to assess noise emissions from cooking fume extractors, facilitating compliance with noise regulations and product labeling requirements.

• Consumer Information Accurate noise emission data derived from standardized testing helps consumers make informed choices when selecting kitchen ventilation products, balancing performance with acoustic comfort.

• Quality Control Manufacturers implement routine noise testing under IEC 60704-2-13 guidance as part of production quality control to ensure consistency in airborne noise emissions across product batches.

Related Standards

• IEC 60704-1:2010 – General requirements for the determination of airborne acoustical noise from household electrical appliances; this standard must be read in conjunction with Part 2-13 for complete testing protocols.

• IEC 60704-3 – Guidelines for the declaration and verification of noise emission values, which complements the measurement procedures outlined in IEC 60704-2-13.

• ISO 3743-1 and ISO 3743-2 – Acoustic measurement standards applicable to small movable noise sources, referenced for the comparison and engineering methods in measuring household appliance noise.

• ISO 3744 – Standard for sound power level determination of noise sources of any size, referenced within IEC 60704-2-13 for test environment setup and measurement accuracy.

This standard plays a critical role in the consistent assessment of airborne noise for kitchen ventilation appliances, driving innovation and customer satisfaction by promoting quieter, effective range hoods and cooking fume extractors worldwide.
