• Improving end-user safety and reducing liability,
• Smoother market entry, whether local or global, thanks to universally recognized standards,
• Lower product recall and warranty costs,
• Earning consumer confidence in new-to-market or IoT-integrated home wellness devices.

Notable features or requirements

• Focused compliance steps for newly emerging technologies (such as LED-based treatments),
• Enhanced definitions and limits for both emission and fail-safe mechanisms,
• Guidance on labeling and instruction manuals that match digital/connected appliances.

Key highlights:

• Robust protection against accidental skin overexposure
• Strict limits on radiation output and exposure duration
• Enhanced user warning systems and labeling

SIST EN IEC 60704-2-4:2025 – Noise Measurement Standards 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 offers a globally harmonized test code for measuring the airborne sound emitted by washing machines and spin extractors (laundry centrifuges) intended for household and similar applications. This fourth edition brings substantial updates to match the pace of smart appliance advancement.

What does this standard cover?

It prescribes standardized test environments and procedures for measuring sound power levels emitted by:

• Single-unit household washing machines,
• Combined washing/spinning appliances,
• Standalone spin extractors.

While declaration of noise values is outside its scope, it provides the basis for comparative assessment and objective measurement across brands and models.

Key requirements and specifications

• Test setup and environment: Defines precise room acoustics, placement, and operation conditions to replicate real-world usage.
• Measurement methods: Details instrumentation, calibration, and procedures to capture and calculate noise levels,
• Specific appliance features: Addresses special requirements for multi-drum machines, wall-mounted washers, and evolving washing technologies.
• Alignment with other standards: References and integrates with IEC 60704-1:2021 (general acoustical test code) and IEC 60456:2024 (performance measurements for washing machines).
• Updated technical definitions: Standardizes the notion of drum speed, test loads, and load distribution for better repeatability and cross-comparison.

Who needs to comply?

• Appliance original equipment manufacturers (OEMs) and designers,
• Testing laboratories and certification bodies,
• Retailers, importers, and white-label product providers,
• Maintenance providers and quality assurance teams wishing to validate in-service performance.

Industry Impact & Compliance

Adopting international standards like IEC 60335-2-27 and SIST EN IEC 60704-2-4 is no longer a matter of mere compliance—it’s a strategic advantage for manufacturers, retailers, and service providers in the entertainment and home appliance industries.

How standards affect businesses

• Market access: Most regions require documented compliance for product entry, especially for electrical safety and environmental performance.
• Brand trust and consumer safety: High-profile incidents with unsafe or noisy equipment can tarnish reputations for years; standards safeguard against these risks.
• Cost and risk management: Reduced risk of recalls, warranty claims, and legal actions translates to lower operational costs and higher margins.

Compliance considerations

• Certification: Many markets demand third-party certification proving adherence to relevant standards.
• Documentation: Full, accurate records of design, testing, and compliance evidence are increasingly required—especially as digitalization and remote audits become standard.
• Continual updating: Standards evolve. Keeping up-to-date and revising products accordingly is essential to maintain legal access and competitiveness.

Benefits of adopting these standards

• Improved productivity through clear design and testing protocols
• Safer, more reliable appliances that build consumer loyalty
• Simpler scalability—products can be more readily adapted for new markets or integrated with IoT/smart home platforms
• Reduced risk profile and enhanced ability to innovate safely

Risks of non-compliance

• Regulatory rejection (blocking or suspension of sales)
• Litigation arising from consumer injury or dissatisfaction
• Market share erosion due to lack of consumer trust

Implementation Guidance

Deploying these international standards successfully calls for a systematic, well-documented approach:

Common implementation steps

1. Gap analysis: Compare your current designs and processes to the relevant standards, noting where updates are needed.
2. Staff training: Ensure design, production, and quality teams understand the requirements, including any technical terminology or test procedures.
3. Prototyping and pre-compliance testing: Early-stage testing minimizes expensive late-design changes.
4. Documentation: Create comprehensive records of all findings, tests, and compliance steps (crucial for audits and market approvals).
5. Certification: Engage with a recognized testing/certification body early to get feedback and smoothen the certification process.
6. Continuous improvement: Monitor feedback, incident reports, and new editions to keep products—and associated documentation—up to date.
