Automatic Cord Reels Endurance Lab Tester
Product details: Model ZLT-JX.
To determine endurance of automatic cord reels , in accordance with IEC60335-1 clause 22.16 and UL1017 clause 5.16.
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. 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°or 90°. The cord is allowed to be recoiled by the reel.
The test is carried out 6 000 times at a rate of approximately 30 times per minute (or 10 times per minute, in accordance with UL1017 clause 5.16)or at the maximum rate allowed by the construction of the cord reel if this is less.
