IEC 60335-1 Clause 22.16 Automatic Cord Reels Endurance Testing
Equipment
Product information
The device is used to detect automatic cord reels, and it conforms
to IEC60335-1 clause 22.16.
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.
When 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.
