IEC 60704-2-13:2023

Overview

IEC 60704-2-13:2023 is an international standard published by the International Electrotechnical Commission (IEC) that specifies test methods for determining airborne acoustical noise emitted by cooking fume extractors used in households and similar environments. This latest fourth edition supersedes the 2016 release and introduces a technical revision aligning it with recent standards such as IEC 61591:2023 and IEC 60704-1:2021.

The standard applies to cooking fume extractors, including range hoods, down-draft systems, and built-in extractor units. It covers extractors intended to filter air inside a room or exhaust air outside, whether the fan is directly attached or mounted separately but controlled by the appliance. Notably, this document focuses solely on noise emissions within the room from which fumes are extracted, excluding noise along external ducts or outside the premises.

By providing consistent measurement conditions and methods, IEC 60704-2-13:2023 enables manufacturers, testing labs, and regulatory bodies to reliably assess and compare the acoustical noise performance of household cooking fume extractors.

Key Topics

• Scope and Applicability: Defines cooking fume extractors covered, including wall, island, ceiling, and built-in range hoods, microwave hood combinations, and down-draft systems.

• Measurement Methods and Environments: Details standardized setups for measuring sound power levels and sound pressure emitted indoors under typical operating conditions.

• Instrumentation and Testing Procedures: Specifies the requirements for test instruments, test enclosures, standard loads simulating cooking conditions, and appliance operational modes during testing.

• Noise Emission Parameters: Focuses on airborne acoustical noise within the room, specifying noise measurement procedures in recirculation and extraction modes.

• Definitions and Terminology: Clarifies terms such as cooking fume extractor (CFE), range hood types, multiple combination hoods, and down-draft systems per IEC 61591:2023.

• Alignment with Related Standards: Harmonizes test protocols with IEC 60704-1:2021 general requirements for electrical appliance noise testing and IEC 61591:2023 performance measurement methods for cooking fume extractors.

Applications

IEC 60704-2-13:2023 serves as a critical reference for:

• Manufacturers of Cooking Fume Extractors: Guiding design verification and product development to meet noise emission performance criteria and provide reliable data for market registration.

• Testing Laboratories: Standardizing noise measurement procedures to ensure comparability of test results across various labs and products internationally.

• Regulatory Authorities and Certification Bodies: Enabling consistent evaluation for compliance with noise regulations applicable to household appliances, ensuring consumer comfort and environmental noise control.

• Product Certification and Labeling: Supporting acoustic performance ratings and noise labeling for cooking fume extractors, assisting consumers in making informed purchasing decisions.

• Research and Development: Facilitating innovation around low-noise cooking ventilation systems by providing objective evaluation methods for acoustical noise emissions during typical use.

Related Standards

• IEC 60704-1:2021 - General requirements for the determination of airborne acoustical noise from household electrical appliances. IEC 60704-2-13:2023 should be used in conjunction with this part for comprehensive acoustical testing.

• IEC 61591:2023 - Methods for measuring the performance of cooking fume extractors. Provides definitions and testing approaches aligned with acoustic noise evaluation.

• ISO 7235:2003 - Laboratory measurement procedures for ducted silencers and air-terminal units, relevant for understanding flow noise and pressure loss in ducted systems as encountered in cooking fume extraction.

Summary

The IEC 60704-2-13:2023 standard delivers essential technical requirements and testing codes for measuring airborne acoustical noise from household cooking fume extractors. By specifying consistent measurement environments, instrumentation, and procedures tailored to various extractor configurations, it ensures reliable, comparable noise data that supports manufacturers, testing bodies, and regulators. Its harmonization with related international standards enhances global applicability and facilitates improvements in kitchen appliance noise performance, helping create more comfortable indoor environments. This standard is vital for any stakeholder aiming to meet recognized noise emission benchmarks for cooking fume extractors.
