IEC 60335-2-24 clause 22.112

Doors and lids of compartments in appliances test equipment

22.11 2 The doors and lids of compartments in appliances with a free space shall be capable of being opened from the inside.
Compliance is checked by the following test.
The empty appliance is disconnected from the supply, placed on a horizontal support and levelled in accordance with the instructions for installation, with castors and rollers, if any, oriented, adjusted or blocked so as to prevent the appliance from moving. Locks, if any, on doors or lids are left unlocked.
Doors and lids are closed for a period of 15 min.
A force is then applied to a point, equivalent to an accessible inside point, of each appropriate door or lid of the appliance, at the midpoint of the edge farthest from the hinge axis in the direction perpendicular to the plane of the lid or door.
The force shall be applied at a rate not exceeding 15 N/s and the lid or door shall open before the force exceeds 70 N.

IEC 62552 clause 11.2 ,clause 11.3

Endurance test for doors ,lids and drawers

11.2 External doors and lids
11.2.1 Test conditions/preparation
The ambient temperature shall be between +16 °C and +32 °C.
The refrigerating appliance shall be switched off.
The door shelve(s) shall be loaded in accordance with 13.3.2.8 or Clause 12, as appropriate.
11.2.2 Opening sequence (see Figure 4)
The movement of the door shall be controlled from an angle of 0° to an angle of opening between 5° and 15°, followed by a free movement of the door, the controlled movement being approximately sinusoidal. The opening of the door shall take place in the first quarter of the period of the cycle.
11.2.3 Closing sequence (see Figure 4)
The movement of the door shall be controlled from the angle of opening of 45° to an angle between 40° and 35°, followed by the free movement of the door and its closing as in normal use.
The number of cycles per minute shall be 10 to 25.
– For compartments with an internal temperature T W − 6 °C, external doors and lids shall withstand 100 000 opening and closing operations without deterioration which could be prejudicial to the air- tightness of the door or lid.
– For compartments with an internal temperature T u − 6 °C, external doors and lids shall withstand 30 000 opening and closing operations without deterioration which could be prejudicial to the air-tightness of the door or lid.
Compliance shall be checked after the procedure using the test according to Clause 9.

11.3 External drawers
11.3.1 Test conditions/preparation
The ambient temperature shall be between +16 °C and +32 °C.
The refrigerating appliance shall be switched off.
All baskets, shelves and containers shall be loaded in accordance with Clause 12.
11.3.2 Opening sequence (see Figure 5)
The drawers shall be pulled out to within 15 mm to 20 mm of their fully open position.
11.3.3 Closing sequence (see Figure 5)
The drawers shall be closed as in normal use from within 15 mm to 20 mm of their fully open position.

The number of cycles per minute shall be between 5 and 10.
– For compartments with an internal temperature T W − 6 °C,
1) single drawers shall withstand 100 000, and
2) multiple drawers shall each withstand 50 000,
opening and closing operations without deterioration which could be prejudicial to the air-tightness of the drawer sealing.
– For compartments with an internal temperature T u − 6 °C, each drawer shall withstand 30 000 opening and closing operations without deterioration which could be prejudicial to the air-tightness of the drawer sealing.
Compliance shall be checked after the procedure using the test according to Clause 9.
