Climatic Test Chamber

Climatic Test ChamberTemperature cycling as per IEC 62133-1 (2017 or BIS : 16046 (Part 1): 2018a) Requirements: Repeated exposure to high and low temperatures shall not cause leakage, fire or explosion.b) Test according to the following procedure and the profileFully charged cells or batteries are subjected to temperature cycling (−20°C, +75°C), in forced draught chambers, according to the following procedure:Step 1: Place the cells or batteries in an ambient temperature of +75°C ± 2°C for 4 h.Step 2: Change the ambient temperature to 20°C ± 5°C within 30 min and maintain at this temperature for a minimum of 2 h.Step 3: Change the ambient temperature to −20°C ± 2°C within 30 min and maintain at this temperature for 4 h.Step 4: Change the ambient temperature to 20°C ± 5°C within 30 min and maintain at this temperature for a minimum of 2 h.Step 5: Repeat steps 1 to 4 for a further four cycles. Transition from Step 4 to Step 1 within 30 min.Step 6: After the fifth cycle, store the cells or batteries and conduct a visual check after a rest period of at least 24 h.NOTE: This test is performed in a single chamber
