This corrigendum addresses corrections and clarifications to the main edition, ensuring the standard stays accurate and relevant. Ensuring user safety is paramount when dealing with equipment that can potentially cause skin burns, eye damage, or other biological effects if misused or malfunctioning.

Key requirements include:

• Specific construction and design mandates to limit accidental exposure to harmful radiation.
• Clear labeling and user instructions to prevent misuse and promote safe operation.
• Verification methods for radiant exposure limits and safety interlock mechanisms.
• Consideration for indoor environments typical of household and similar use (as opposed to robust industrial or outdoor settings).

Who needs to comply:

• Manufacturers of beauty, therapeutic, and skin treatment appliances that emit optical radiation.
• Importers and retailers distributing such devices in regulated markets.
• Test laboratories certifying safety of these products for consumer use.

Practical implications:

• Direct impact on brand reputation and user trust for home skin care and therapy brands.
• Marketplace access hinges on conformity with this standard in many geographies.
• Reduces product liability risks by governing safe design and clear consumer guidance.

Notable requirements:

• Ensuring automatic shut-down or attenuation of optical emissions when protective covers are opened.
• Limits on UV and other optical irradiation in line with biophysical safety data.
• Correction of errors/translations in prior text editions.

Key highlights:

• Protects users from overexposure to potentially harmful optical radiation
• Mandates rigorous safety features and user instructions
• Facilitates market access and legal compliance for new electronic beauty and therapy devices

SIST EN IEC 60704-2-4:2025 – Noise Test Code for Washing Machines and Spin Extractors

Household and Similar Electrical Appliances – Test Code for the Determination of Airborne Acoustical Noise – Part 2-4: Particular Requirements for Washing Machines and Spin Extractors (IEC 60704-2-4:2025)

The SIST EN IEC 60704-2-4:2025 standard is a cornerstone for assessing airborne acoustical noise of household and similar washing machines and spin extractors, advancing both user comfort and product transparency in a noisy, technology-filled world.

Applies to:

• Electric washing machines (including those with both washing and spinning functions)
• Spin extractors intended for home or similar environments
• Multi-compartment and wall-mounted (compact) washing machines—a nod to modern appliance innovations

Scope and approach:

• Defines test methods, reference conditions, and measurement environments for reliable, repeatable sound power level assessment.
• Promotes comparability of noise emissions between brands and models, empowering informed consumer choices.
• This edition introduces technical updates for alignment with the latest IEC 60704-1:2021 (general acoustical requirements) and IEC 60456:2024 (performance of washing machines), covering new appliance types and operational practices.

Key requirements and specifications:

• Precise measurement of airborne noise during typical washing and spinning cycles.
• Adjustments for emerging appliance formats (multi-drum, wall-mounted) and updated detergent/test load standards.
• Defines essential test data reporting, including environmental conditions, equipment set-up, and calculated sound power levels.
• Excludes declaration of noise emission values in user product literature; instead, it standardizes testing for those seeking accurate, verifiable data.

Who needs to comply:

• Manufacturers, laboratories, and certification bodies involved with electrical laundry appliances.
• Product designers and engineers striving for market differentiation through lower noise emissions.
• Regulatory authorities and environmental agencies setting requirements for acoustical emissions.

Practical implications:

• Consumers experience quieter homes and workspaces as appliances meet stricter noise limits.
• Product marketing can boast independently verified, standardized noise performance.
• Facilitates interoperability and innovation, particularly as home automation integrates laundry appliances with other home and entertainment systems.
