IEC 60884-1 Clause 14.23.2 | IEC 60335-1 Clause 22.3 | IEC 62368-1 Clause 4.7 Plug Torque Tester

The LSPTT-1 Plug Torque Tester is a precision measurement instrument engineered to verify the mechanical torque exerted by plug-equipped devices on fixed output sockets. Utilizing a calibrated balance adjustment mechanism, this apparatus simulates operational insertion conditions to quantify the rotational force applied to socket interfaces. The optimized mechanical configuration enables accurate torque measurement, facilitating determination of compliance with international safety standards for socket engagement integrity.

Compliance Standards:

Technical Specifications:

• Socket Compatibility: Universal socket (GB/BS plug compatible), UL socket, European socket
• Weight Configuration: 1N, 1.25N, 2.5N (one each)

Application Scenarios:

1. Torque verification testing of household appliances with integrated plugs for fixed socket engagement
2. Compliance assessment of plug-equipped devices per IEC 60884-1, IEC 60335-1, IEC 60065, and IEC 62368-1 requirements
3. Mechanical torque evaluation of electronic devices with diverse plug specifications during socket mating
4. Manufacturing quality control verification of plug torque performance prior to product release
5. Third-party certification testing by quality inspection agencies for plug-related device compliance

Test Procedure:

1. Configure the test weight on the apparatus right side, positioning its left edge at the 10mm reference on the steel ruler
2. Calibrate the balance weight on the counterbalance arm to establish equilibrium
3. Proceed with standardized torque measurement protocol
