Electrical Appliance Tester Automatic Cord Reels Endurance Testing Equipment with 30 times/min Test rate
Standard:
IEC 60335-1 Household and similar electrical appliances – Safety – Part 1: General requirements clause 22.16
Standard description:
Automatic cord reels shall be constructed so that they do not cause
– undue abrasion or damage to the sheath of the flexible cord;
– breakage of conductor strands;
– undue wear of contacts.
Compliance is checked by the following test, which is carried out without passing current through the flexible cord.
Two-thirds of the length of the cord is unreeled. If the withdrawable length of the cord is less than 225 cm, the cord is unreeled so that a length of 75 cm remains on the reel. An additional length of 75 cm of the cord is then unreeled and pulled in a direction so that the greatest abrasion occurs to the sheath, taking into account the normal position of use of the appliance. Where the cord leaves the appliance, the angle between the axis of the cord during the test and the axis of the cord when it is unreeled without substantial resistance is approximately 60°. The cord is allowed to be recoiled by the reel.
If the cord does not recoil at the angle of 60°, this angle is adjusted to the maximum that will allow recoil.
The test is carried out 6 000 times at a rate of approximately 30 times per minute or at the maximum rate allowed by the construction of the cord reel if this is less.
After this test, the cord and cord reel are inspected. In case of doubt the cord is subjected to the electric strength test of 16.3, a test voltage of 1 000 V being applied between the conductors of the cord connected together and metal foil wrapped around the cord.
