• Applies to electrical appliances intended for skin exposure to optical radiation in homes, salons, and similar environments.
• Defines strict safety and performance requirements to mitigate risks such as burns, excessive UV exposure, and electrical faults.
• Clarifies distinctions between medical and non-medical devices, making it clear which regulatory paths to follow.
• Includes mandatory safeguards addressing circuitry, control interlocks, user notifications/warnings, and fail-safe operation.
• Specifies material and design criteria to withstand thermal and optical stresses without degrading safety functions.

Target Audience and Compliance:

• Manufacturers of optical radiation devices for skin treatment
• Product designers and certification bodies
• Home and professional appliance distributors
• Regulatory and quality assurance professionals

Implementation Implications:

• Requires a combination of robust design, precise instruction manuals, and clear hazard warnings.
• Regular performance testing and quality control in accordance with the latest corrections.
• All updates—including those in this corrigendum—should be reflected promptly in design documentation and certification workflows.

Key highlights:

• Enhanced user safety for skin exposure appliances

SIST EN IEC 60704-2-4:2025 - Acoustical Noise Measurement for Washing Machines and Spin Extractors

Full Title: 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)

Noise performance is both an entertainment and comfort factor in the home. Excessive appliance noise is a common consumer complaint and a major influencer in purchasing decisions. The SIST EN IEC 60704-2-4:2025 standard establishes internationally harmonized testing protocols for measuring airborne acoustical noise from washing machines and spin extractors. As energy-efficient, multi-function, and wall-mounted appliances become commonplace, consistent measurement and reporting is critical for fair comparisons and transparent labeling.

Scope and Key Requirements:

• Applies to single-unit household washing machines, combined appliances’ washing and spinning functions, and spin extractors for household or similar use.
• Covers a wide variety of configurations, including multi-compartment and wall-mounted washing machines.
• The standard explicitly does not cover washer-dryers—these are regulated under a related standard (IEC 60704-2-16:2019).
• Aligns with recent technical revisions in general test methods (IEC 60704-1:2021) and washing machine performance metrics (IEC 60456:2024), focusing on:
  • Test program and detergent protocols
  • Standard test load definitions
  • Drum speed measurement
• Measurement conditions and instrumentation requirements ensure results are reproducible across manufacturers and laboratories.

Who Needs to Comply:

• Manufacturers and importers of washing machines and spin extractors
• Quality and product compliance engineers
• Retailers aiming to provide verified acoustical data
• Laboratories performing third-party acoustic testing

Practical Implementation:

• Ensures that consumers receive accurate, comparable noise performance data when selecting appliances
• Facilitates fair market competition based on verified product claims
• Mandates specific test environments, recording, and reporting formats, which must be strictly adhered to in product development
• Aids in the communication of acoustical performance to regulatory agencies and in advertising

Key highlights:

• Harmonized testing for next-generation washing appliances
• Addresses technical advances in appliance design
• Enhances consumer trust and supports eco-labeling initiatives

Industry Impact & Compliance

The rise of smart homes, personalized entertainment, and multifunctional household technologies means standards like these are pivotal for business continuity and sustained innovation. Compliance ensures that:

• Products gain global market acceptance, with clear documentation for regulatory authorities around the world
• Consumers are protected, leading to fewer recalls and warranty claims
• Brands maintain competitiveness and reputation through third-party validation and performance transparency
• Operational risks are minimized, especially when introducing new technologies (e.g., optical radiation devices or advanced laundry appliances)
• Scalability and productivity are improved, as standardized protocols support smoother international manufacturing, distribution, and maintenance

Non-compliance, by contrast, risks market exclusion, legal penalties, damaged reputation, and increased liability for unsafe or misleading products.

Implementation Guidance

Transitioning to meet the requirements of updated or new appliance standards can seem daunting. However, the following best practices streamline the process:

1. Early Integration in Design: Design teams should implement relevant standards—such as those governing safety for optical radiation or noise test methods—at the earliest development phases. This preemptively addresses compliance and reduces costly redesigns.
2. Dedicated Standard Operating Procedures (SOPs): Document and institutionalize testing and safety review procedures. Regularly update these as standards evolve.
3. Invest in Training: Ensure engineers, quality controllers, and regulatory teams are well-versed in the latest requirements, including recent corrigenda or revisions.
4. Utilize Accredited Testing Services: Work with certified laboratories for both pre-market and post-market testing. This is critical for noisy appliances and safety-sensitive devices.
5. Consistent Documentation and Labeling: As required by the standards, maintain detailed records of measurements, test conditions, results, and product modifications. Accurately label appliances to reflect true performance data.
6. Continuous Monitoring: Stay up to date with corrections, amendments, and best practices issued by standardization bodies.
