IEC 60335-1 Automatic Cord Reels Flexible Cord Withdrawn Testing
Apparatus
Standards for Automatic Cord Reels Flexible Cord Withdrawn Testing
Apparatus:
This device meets the standards of IEC 60335-1 Clause 22.16
Application for Automatic Cord Reels Flexible Cord Withdrawn
Testing Apparatus:
It is used to check the 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.
Technical Characteristics for Automatic Cord Reels Flexible Cord
Withdrawn Testing Apparatus:
| Input Power | 220V/50Hz |
| Gas Source Pressure | 0.6MPa |
| Test Speed | 30 cycles / min (or at the maximum rate allowed by the construction
of the cord reel if this is less) |
| Test Cycles | 0~9999 times, the test device will stop working automatically when
the preset test cycles are finished |
| Drive Mode | Pneumatic |
| Withdrawable Angle | 30~70°, can be preset |
| Fixture | Quick clamping fixtures, easy for clamping the test sample |
| Withdrawable Stroke | Maximum 1000mm, can be adjusted |
Test procedures (extracted from IEC 60335-1: 2016 clause 22.16):
Two-thirds of the length of the cord is inreeled. If the
withdrawable length of the cord is less than 225cm, the cord is
unreeled so that a length of 75cm remains on the reel. An
additional length of 75cm of the cord then unreeled and pulled in a
director 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
adjustaed to the maximum that will allow recoil.
The test is carried out 6000 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.
Test sample for Automatic Cord Reels Flexible Cord Withdrawn
Testing Apparatus:
Automatic cord reels of household appliances and similar electrical
appliances.
Feature: The device adopts a multi-functional fixture, large work
surface, can test cord reels up to 300cm, test speed (5-30 times /
min) is adjustable, and it is suitable for most test electrical
products.
How to install the test sample on the proper position?
The nut of the sample mounting platform is placed in the groove and
can be moved. Therefore, the fixing bracket can be installed at any
position to accommodate various samples. If the sample reel has the
control switch, should make the control switch in the open state.
