1. Product Overview
The flame-retardant enclosure verification test chamber for A2L refrigerant is mainly used to test and verify the flame-retardant effect of flame-retardant enclosures in the event of A2L refrigerant leakage. The equipment complies with the requirements of IEC 60335-2-40:2022 and GB/T 4706.32-2024 standards. This test chamber simulates refrigerant leakage scenarios to test the flame-retardant performance of the enclosure after leakage.
2. Equipment Functions and Standards
This testing machine is designed according to international standards IEC 60335-2-40:2022 and GB/T 4706.32-2024, and is suitable for household appliances such as electric heat pumps, air conditioners, and dehumidifiers.
Its core functions include:
Simulating a refrigerant leak scenario, the flame-retardant effect of the flame-retardant enclosure was tested after the leak.
Verify whether the casing can effectively prevent the spread of flames after a leak.
