What is EN 60335-2-40:2020?

EN 60335-2-40:2020 is a technical standard that sets safety requirements and testing procedures for electric heat pumps, air conditioners, and dehumidifiers. The standard was developed by the European Committee for Electrotechnical Standardization (CENELEC) and is applicable to both household and similar electrical appliances. Its purpose is to ensure the safe operation of these appliances and protect users from potential hazards.

Scope and Application

The scope of EN 60335-2-40:2020 includes various types of electric heat pumps, air conditioners, and dehumidifiers that are used in residential, commercial, and industrial environments. It applies to both standalone units and those integrated into other equipment or systems. The standard covers aspects such as electrical safety, temperature control, mechanical hazards, airflow, noise levels, and protection against moisture ingress. Compliance with this standard is mandatory in the European Union, and manufacturers must ensure their appliances meet its requirements before placing them on the market.

Main Requirements and Testing Procedures

EN 60335-2-40:2020 outlines specific requirements that must be met by electric heat pumps, air conditioners, and dehumidifiers to ensure their safe operation. These include insulation resistance, earthing, protective bonding, creepage distances, clearances, and many others. The standard also provides guidelines for testing methods to verify compliance with these requirements. Testing involves assessing aspects like electrical continuity, dielectric strength, temperature rise limits, protection against water penetration, and mechanical strength. Manufacturers are responsible for conducting these tests or having them performed by accredited testing laboratories.

Updates and Impact

EN 60335-2-40:2020 is a revised version of the previous standard, EN 60335-2-40:2015. The updated standard introduces several changes and improvements to enhance safety levels and keep up with technological advancements. For example, it includes specific requirements for devices with wireless communication capabilities or remote control functionalities. Additionally, the revised standard addresses issues related to efficiency, energy consumption, and environmental impact. Compliance with the updated standard ensures that electric heat pumps, air conditioners, and dehumidifiers meet the latest safety and performance standards, providing peace of mind for consumers and promoting sustainable practices.
