IEC 60335-1 Household Appliances Supply Cord Anchorage Pull Force And Torque Test Machine
Standards & Clauses:
IEC60335-1:2016 “Household and similar electrical appliances-Safety-Part1:General requirements” clause 25.15
IEC60884-1:2013 “Plugs and socket-outlets for household and similar purposes- Part1:General requirements” clause 23.2
IEC60745-1:2006 “Safety of hand-held motor operated electric tools Part1:General requirements” clause 24.14
IEC60598-1:2014 “Luminaries-Part1:General requirements and tests” clause 5.2.10.3
IEC60065:2005 “Audio, video and similar electronic apparatus-Safety requirements” clause 16.5
Samples and Restrictions:
Plugs for connecting flexible cables, fixed or mobile sockets; hand-held power tools; household appliances with flexible cord anchorage (eg induction cookers, washing machines); lamps with cables and wires; audio and video and related signal electronic devices with flexible cords (such as projectors)
Application:
The cord anchorage shall relieve conductors from strain, including twisting, at the terminals and protect the insulation of the conductors from abrasion. This testing appliance applies pull force and torque tests for cord anchorage, to verify the reliability of the cord anchorage.
Test Principle:
The eccentric wheel is driven by a motor, to make the pull weight pulled for 1s; the torque is applied to the sample by the electromagnet releases the torque weight, at the same time, the direction of the force applied and the axis of the sample form a torque arm through the torque wheel, so as to achieve torque test. The pull weights and torque weights can be customized to meet different requirements in different standards.
Structure:
The equipment adopts motor cam ejector mechanism, the pull fixture is combined with the torque fixture, and matched by the bearing in the middle to reduce the friction during the torque test. The Z-shaped structure enables the fixture to clamp the appliance’s power cord which is 150mm above the bottom surface. It can test the firmness of the power cord anchorage of large household appliances, such as refrigerators and washing machines
