IEC 60601 vs IEC 61010: Key Differences Explained

IEC safety standards help define the requirements that electrical and electronic equipment must meet for safe use in specific applications. For power supplies, the relevant standard depends on the type of equipment being powered, the operating environment and the market where the final product will be used.

This guide explains the differences between IEC 60601, IEC 60335 and IEC 61010, including how they relate to medical equipment, household or similar appliances, laboratory equipment, industrial control systems and certified power supply selection.

Why IEC Safety Standards Matter When Choosing a Power Supply

Safety standards help ensure that electrical products are assessed against recognised requirements for protection against hazards such as electric shock, fire, excessive temperature, electromagnetic disturbance and mechanical risk. For power supplies, this is especially important because the PSU is often built into, connected to or specified as part of a wider electrical system.

The same voltage, wattage or form factor is not enough to confirm suitability. A power supply used in medical equipment may need to meet different requirements from one used in a laboratory instrument, appliance, control system or industrial device. Reviewing certification requirements early can help reduce redesign work, avoid compliance delays and ensure the selected power supply is appropriate for the final application.

IEC 60601 vs IEC 61010: What Is the Difference?

IEC 60601 and IEC 61010 apply to different categories of electrical equipment. IEC 60601 is used for medical electrical equipment and medical electrical systems, while IEC 61010 is used for measurement, control and laboratory equipment.

For power supply selection, this distinction matters because the end application determines which safety requirements are relevant. A power supply used in medical equipment may need to support IEC 60601-related requirements, while equipment used in test, measurement, laboratory or industrial process-control environments may fall under IEC 61010.

Choosing the wrong standard at specification stage can create compliance issues later in product development, so the intended use and final equipment category should be reviewed before selecting a power supply.

What Is IEC 60601-1-2?

IEC 60601-1-2 is part of the IEC 60601 series for medical electrical equipment and focuses specifically on electromagnetic compatibility, often shortened to EMC. In simple terms, it looks at how medical equipment behaves when exposed to electromagnetic disturbance, and how much electromagnetic interference that equipment may emit into its surrounding environment.

This is especially important in healthcare settings, where multiple electronic devices may operate close together. Medical equipment must be able to function safely and reliably without being disrupted by nearby devices, radio-frequency signals, electrostatic discharge or other sources of interference.

For power supplies used in medical applications, EMC performance is an important part of overall suitability. The PSU must support the wider equipment’s safety and performance requirements, particularly where the final product will be used near sensitive medical devices or in regulated healthcare environments.

What Is IEC 60335-1?

IEC 60335-1 is a safety standard for household and similar electrical appliances. It covers products used in domestic environments, as well as some commercial or light industrial appliances that could present similar risks to users.

The standard considers hazards such as electric shock, fire, excessive temperatures, mechanical risks and other safety issues that may arise during normal use or foreseeable misuse. It can apply to appliances powered from AC mains, battery-operated appliances and DC-supplied products, depending on the equipment and application.

For power supply selection, IEC 60335-1 may be relevant where the PSU is used within or alongside an appliance-type product. This could include equipment used in cleaning, catering, personal care, light industry, agriculture or other similar environments. In these cases, the power supply should be reviewed as part of the wider product design, including output rating, insulation, thermal performance, protection features and the final appliance’s intended operating conditions.

What Is IEC 61010-1?

IEC 61010-1 is a safety standard for electrical equipment used in measurement, control and laboratory environments. It is commonly relevant to products such as test equipment, laboratory instruments, meters, analysers, monitoring systems and industrial process-control equipment.

The purpose of the standard is to reduce risks to operators, surrounding equipment and the operating environment. It considers hazards such as electric shock, fire, excessive temperature, mechanical risks, fluid pressure, radiation and other potential dangers associated with specialist electrical equipment.

When a power supply is used in this type of equipment, it must meet the safety requirements of the complete system. This means considering not just the output voltage and power rating, but also insulation, protection features, thermal behaviour, operating environment and the role of the PSU within the final product.

How These Standards Relate to Power Supplies

These standards matter because a power supply is often only one part of the final certified product or system. A PSU may be suitable for one application but inappropriate for another if the equipment category, installation environment, output rating, insulation requirements or final product standard is different.

For example, a medical device may require power supply characteristics aligned with medical electrical equipment requirements, while a laboratory instrument may be assessed under IEC 61010. Similarly, appliances and similar products may need to consider IEC 60335-related requirements.

Reviewing standards early helps prevent specification issues later in the project. This is particularly important for OEMs, product designers, medical device manufacturers, appliance manufacturers, laboratory equipment suppliers and companies developing products for multiple territories.

Choosing a Certified Power Supply

When choosing a certified power supply, the first step is to understand the final application. The product category, operating environment, required output, isolation requirements, leakage current, protection features, and target market can all influence which approval route is appropriate.

It is also important to check whether the final product requires specific safety, EMC or regional markings before the power supply is selected. A technically suitable PSU may still be unsuitable if it does not support the certification requirements of the complete equipment.

Product Conformity Certifications and Marks Worldwide

Once the relevant national and international standards have been identified, it is important to understand how product conformity is demonstrated. Certification marks show that a product has been assessed against specific safety or regulatory requirements for a target market.

The required mark or approval will depend on the product type, where it will be sold and how it will be used. A power supply used in medical equipment, laboratory equipment, an appliance or an industrial control product may be subject to different requirements. For this reason, conformity should be reviewed as part of the specification process rather than after product selection.

If you are unsure which standard or approval applies to your application, it is best to confirm requirements early with your supplier, certification body or compliance specialist.
