In today’s competitive marketplace, ensuring that household appliances meet international safety standards is non-negotiable. For manufacturers, importers, and distributors of home appliances, compliance with the IEC 60335 series is essential—not just for market access but for protecting users and building trust. In this blog, you’ll discover what IEC 60335 is, why it matters, how testing is done, and specific key requirements you should be aware of.

What is IEC 60335 Testing?

The IEC 60335 standard (formally titled “Household and Similar Electrical Appliances – Safety”) is the benchmark safety standard for household and similar electrical appliances.

Key points about IEC 60335:

• The standard is published by the International Electrotechnical Commission (IEC), which sets international norms for electrical and electronic technologies.
• The primary part, IEC 60335-1, details general safety requirements, testing, markings, classifications and instructions for household appliances.
• The “Part 2” standards (IEC 60335-2-xxx) cover particular requirements for specific appliances (e.g., washing machines, dishwashers, hair-care appliances, etc).
• It applies to appliances with voltage ratings not more than 250 V for single-phase appliances and 480 V for other appliances.

Why is it important?

Testing and complying with IEC 60335 ensures that your appliances meet globally recognised safety standards, reducing risk of hazards such as electrical shock, fire, mechanical injury, radiation, or other faults. It helps you access international markets, meet certification requirements, and build brand credibility.

Scope & Appliance Types Covered Under IEC 60335 Testing

The standard covers a wide range of household electrical appliances and “similar” devices (those used by lay-persons in non-industrial settings).

Examples of appliance categories covered under the IEC 60335-2 series:

• Vacuum cleaners and water-suction cleaning appliances (IEC 60335-2-2)
• Dishwashers (IEC 60335-2-5)
• Washing machines (IEC 60335-2-7) (
• Refrigerating appliances, ice-cream appliances and ice-makers (IEC 60335-2-24)
• Appliances for skin or hair care (IEC 60335-2-23) e.g., hair dryers, hair straighteners.

What is not covered?

Appliances intended exclusively for industrial purposes, or to be used under special conditions (e.g., corrosive atmospheres, explosive environments) generally fall outside the standard’s scope.

The IEC 60335 Testing & Compliance Process

Complying with IEC 60335 involves a structured process of design review, testing, documentation and certification. Here are the typical steps:

1. Identify applicable standard(s)

• Determine that IEC 60335-1 applies to your product’s general category.
• Identify the relevant Part 2 standard for your specific appliance type (e.g., IEC 60335-2-5 for dishwashers).
• Check edition / amendment version applicable in your target market (e.g., Edition 6 for IEC 60335-1).
• Assess if local/regional variations (national adoptions) apply.

2. Design for safety

• During product design, implement safety features for electrical, mechanical, thermal, and other hazards (see next section).
• Prepare documentation: user manual, markings, instructions, risk assessment, design drawings, schematics.

3. Laboratory testing

Working with a recognised test laboratory, conduct the required safety tests defined within the standard. Some key tests include:

• Electrical safety / insulation / grounding tests: Ensuring protection against electric shock.
• Mechanical strength, stability tests: Checking outer casings, hinges, tipping hazard, sharp parts.
• Thermal tests / temperature rise tests: Ensuring the appliance does not overheat or create burn hazards.
• Moisture resistance / ingress protection: For appliances subject to splashes or moist environments.
• Abnormal operation tests / fault condition: Simulating misuse or abnormal conditions to ensure safe failure.
• Radiation / optical / hygiene tests: For appliances with optical or UV-light functions, or appliances with hygiene implications.
• Marking, instructions, and manual review: Verifying that all necessary labels and instructions (for safe use) are present.

4. Certification & Reporting

• The test lab issues a test report covering all relevant clauses of the standard.
• If required, certification bodies issue certification (e.g., IECEE CB scheme, region specific marks).
• Manufacturer keeps technical file: design records, test reports, instructions, risk assessment, corrective actions.

5. Post-market surveillance & quality control

• After launch, monitor customer feedback and field issues.
• Maintain quality control and ensure production units conform to the tested sample. Non-conforming units must be prevented.
• Re-testing may be needed when design changes occur or new editions of standard are adopted.

Key Safety Requirements for IEC 60335 Compliance

When preparing for IEC 60335 compliance, these are the critical areas you should emphasise:

Electrical hazard protection

Appliances must protect users from electric shock. This includes appropriate insulation, fault current protection, correct earthing, separation of live parts, child-safety probe accessibility, etc.

Mechanical and structural safety

Your appliance should be designed to prevent hazards like tipping, breaking, sharp edges, entrapment or moving parts causing injury. The casing and internal components must be robust enough.

Thermal safety & fire hazard

Components that heat up (motors, resistors, heating elements) must stay within safe temperature limits. The unit should not pose fire hazard or cause burns to users.

Moisture and ingress protection

For appliances that operate in damp or wet conditions (e.g., bathroom appliances, kitchen devices, outdoor units), resistance to moisture and correct sealing is essential.

Abnormal operation & safety under fault

Appliances must be safe even if they are misused, overloaded, or encounter a fault. This includes thermal cut­outs, safe failure modes, stability under abnormal conditions.

Marking, instructions & user information

All appliances must have clear instructions for safe use, correct markings (voltage, warnings, grounding), and user manuals that align with the standard’s requirements.

Emerging requirements (Smart/Connected Devices)

The latest editions of IEC 60335-1 include new requirements for connected appliances, cybersecurity considerations, battery-operated household appliances and optical radiation hazards.

Challenges Manufacturers Face in IEC 60335 Testing

Challenge 1: Keeping up with revisions

Standards are updated to reflect new technology (IoT, battery, connected appliances). For example, IEC 60335-1 Edition 6 extends to battery-operated and connected devices. Tip: Monitor standard editions, maintain document control, and build flexibility into design to accommodate updates.

Challenge 2: Identifying correct Part 2 standard

With many appliance types each having a specific Part 2 standard (e.g., IEC 60335-2-23 for skin/hair care devices) Tip: Map out your product portfolio, consult a testing house or standards expert to ensure you pick the correct Part 2 clause.

Challenge 3: Laboratory testing & global market access

Selecting the right accredited lab, understanding market-specific acceptance (CB-Scheme, country deviations) can be complex. Tip: Choose labs accredited under IECEE CB scheme or local national certification bodies; plan lead‐time and budget accordingly.

Challenge 4: Design controlled beyond sample

Manufacturers must ensure production units remain same as tested sample—any change could invalidate the whole test report. Tip: Establish robust configuration management, re-test or perform verification when changes occur.

Challenge 5: Documentation & technical file

Failing to prepare full documentation (manuals, drawings, risk assessments) may delay certification or cause non-compliance. Tip: Build the technical file early, ideally during design stage—not at the end.
