IEC 60335-2-104:2021 addresses the safety requirements for appliances used to recover and/or recycle refrigerant from air conditioning and refrigeration equipment. For engineering, procurement, and compliance teams, it serves as a focused technical document for evaluating whether such appliances are designed and assessed with the necessary safety considerations in mind. IEC 60335-2-104:2021 is especially relevant where recovery and recycling functions must be reviewed as part of documented evaluation, product selection, and conformity assessment workflows.

Purpose of IEC 60335-2-104:2021

The purpose of IEC 60335-2-104:2021 is to define particular safety requirements for appliances that handle refrigerant recovery and recycling in HVACR-related applications. It supports technical assessment of equipment intended to work with refrigerants removed from air conditioning and refrigeration systems, helping organizations align design review and verification activities with the specific hazards and operational conditions involved. The document is useful when teams need a compliance reference for safety-focused product evaluation and engineering documentation.

Compliance applications of IEC 60335-2-104:2021

IEC 60335-2-104:2021 is typically applied during product development, laboratory evaluation, and regulatory preparation for appliances that recover or recycle refrigerant. It may be used by manufacturers, test laboratories, and certification teams assessing safety-related requirements before market release or procurement approval. In quality workflows, it can support technical validation, controlled testing workflows, and structured review of electrical equipment intended for refrigerant handling in air conditioning and refrigeration environments.

Benefits of IEC 60335-2-104:2021

Using IEC 60335-2-104:2021 helps organizations improve safety, reduce compliance risk, and create more consistent technical validation for relevant appliances. It can also streamline procurement review by giving buyers and specifiers a clear reference for expected safety coverage. For manufacturers and conformity assessment teams, the document supports more disciplined testing, clearer engineering specifications, and stronger preparation for certification or internal approval processes. It is particularly valuable where operational consistency and documented risk management are important.
