IEC 61000-6-3 is an international electromagnetic compatibility (EMC) emission standard applicable to electrical and electronic equipment used in residential, commercial and light industrial environments.

This standard ensures that your product does not generate excessive electromagnetic disturbances that could interfere with nearby devices such as televisions, communication systems, medical equipment, or industrial electronics.

At ITC India, we provide complete IEC 61000-6-3 emission testing with accurate measurement, detailed reporting, and regulatory guidance for smooth product approval.

What is IEC 61000-6-3?

IEC 61000-6-3 is a generic emission standard issued by the
International Electrotechnical Commission (IEC).

It applies to equipment that:

• Operates in residential areas
• Is used in commercial establishments
• Functions in light industrial environments
• Does not have a specific product EMC standard

It primarily evaluates:

• Conducted emissions
• Radiated emissions
• Harmonic current emissions
• Voltage fluctuations & flicker

Why IEC 61000-6-3 Testing is Important

Non-compliant equipment can:

• Interfere with Wi-Fi and communication networks
• Disturb audio/video equipment
• Affect nearby electronic systems
• Lead to regulatory rejection

Testing ensures:

✔ Market acceptance
✔ CE marking support
✔ Product reliability
✔ Reduced customer complaints
✔ Faster certification approval

Scope of IEC 61000-6-3 Testing

1. Conducted Emission Testing

Measures noise conducted through power lines.

Frequency Range: 150 kHz to 30 MHz

2. Radiated Emission Testing

Measures electromagnetic radiation emitted through air.

Frequency Range: 30 MHz to 1 GHz (or higher depending on product)

3. Harmonics Testing (IEC 61000-3-2)

For equipment drawing input current ≤ 16 A per phase.

4. Flicker Testing (IEC 61000-3-3)

Evaluates voltage fluctuations caused by equipment.

Frequently Asked Questions

Is IEC 61000-6-3 mandatory?

It is required when no specific product EMC standard exists and the equipment is used in residential or commercial environments.

Can IEC 61000-6-3 and IEC 61000-6-1 be tested together?

Yes. Both are complementary standards covering emission and immunity.

Does this support CE marking?

Yes. IEC 61000-6-3 is widely used for CE compliance under EMC Directive.
