SIST EN IEC 60335-2-104:2025/A11:2025

Overview

SIST EN IEC 60335-2-104:2025/A11:2025 is a key European standard that focuses on the safety requirements for electrical appliances designed to recover and/or recycle refrigerants from air conditioning and refrigeration equipment. Published by the CLC (European Committee for Electrotechnical Standardization), this amendment A11 supplements the 2025 edition of EN IEC 60335-2-104, ensuring updated safety protocols for refrigerant recovery appliances. The standard applies specifically to household and similar electrical appliances, highlighting their role in preserving environmental safety and operational effectiveness in refrigerant handling.

Key Topics

• Safety Requirements: The standard defines particular safety measures for appliances used in recovering or recycling refrigerants, ensuring protection against electrical and mechanical hazards associated with refrigerant recovery equipment.
• Scope of Application: Targets recovery/recycle units that handle refrigerants from both air conditioning and refrigeration systems, focusing on minimizing environmental impact and operator safety.
• Compatibility and Compliance: Designed to align with the broader EN IEC 60335 series, including Part 1 (general requirements) and other related parts for electrical household appliances.
• Normative References: Integrates harmonized references to other relevant standards including:
  • IEC 60079 series for explosion protection.
  • IEC 60320 for appliance couplers.
  • IEC 60335-2-34 and IEC 60335-2-40 for motor-compressors, heat pumps, and air conditioners.
  • ISO 5149-2 and ISO 817 regarding refrigerants’ safety classifications and system requirements.
  • SAE standards on refrigerant recovery and recycling specific to automotive air conditioning systems.
• Amendment Details: Includes modifications to clauses and annexes of previous standards, ensuring comprehensive updates on safety and operational requirements.

Applications

EN IEC 60335-2-104:2025/A11 is crucial for manufacturers, testing bodies, and users of electrical appliances involved in refrigerant recovery and recycling processes. Its practical applications include:

• Refrigerant Recovery Units: Equipment designed for extracting refrigerants from HVAC and refrigeration systems safely.
• Recycling Equipment: Devices that purify and prepare refrigerants for reuse, reducing environmental damage and resource waste.
