Overview
IEC 60704-2-3:2025 is an international standard specifying the test code for determining airborne acoustical noise emitted by household and similar electrical dishwashers. This standard applies to single-unit electric dishwashers intended for household use or similar applications, regardless of automatic program control or water supply type. It covers dishwashers fixed or detachable to water and sewage systems, designed for floor-standing, built-in, wall-mounted, or countertop placement.
This fourth edition of IEC 60704-2-3 updates and replaces the 2017 third edition, incorporating key technical revisions such as alignment to the updated IEC 60704-1:2021 general standard, adjustments in test sample positioning, and updated detergent specifications in line with IEC 60436:2025.
Key Topics
-
Scope and Applicability
Targets noise measurement procedures for household dishwashers in various installation types and operating conditions.
-
Measurement Methods and Environments
Describes direct and comparison methods for acoustic noise testing. Addresses environments such as special reverberation rooms, hard-walled test rooms, and requirements to accommodate pure tone components in noise measurement. References ISO standards (ISO 3743-1:2010, ISO 3743-2:2018, ISO 3744:2010) for establishing test environment adequacy.
-
Noise Emission Parameters
Details measurement of sound pressure levels, standard deviations for repeatability (0.4 dB) and reproducibility (0.8 dB), and standard deviations for production, total, and reference noise emission declarations.
-
Appliance Operation and Conditioning
Specifies requirements for preparing dishwashers before noise testing, including cleaning, filling salt and rinse aid containers according to manufacturer instructions, and conditioning cycles with reference detergent to remove manufacturing residues.
-
Test Configuration and Reporting
Outlines the positioning of dishwashers within test enclosures, equipment setup, and the information that must be recorded and reported to ensure comparability and transparency.
Applications
IEC 60704-2-3:2025 is essential for manufacturers, testing laboratories, and regulatory bodies involved in:
-
Product Development and Quality Control
Ensuring dishwashers meet noise emission requirements for consumer comfort and regulatory compliance.
-
Comparative Product Testing
Providing standard methodology to compare acoustical noise emissions across different dishwasher models and brands.
-
Certification and Market Access
Supporting noise certification processes for household appliances, influencing labeling and consumer information programs.
-
Research and Innovation
Enabling more accurate noise measurement to support design improvements targeting noise reduction.
