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 according to IEC 60884-1:2022 Clause 14.23.2 (GB/T 2099.1-2021 Clause 14.23.2), IEC 60335-1:2023 Clause 22.3 (GB/T 4706-2024 Clause 22.3), IEC 60065:2014 Clause 15.4.1 Figure 11 (GB 8898-2011 Clause 15.4.1 Figure 11) and IEC 62368-1:2023 Clause 4.7 (GB/T 4943.1-2022 Clause 4.7). Used to test the torque exerted on a fixed output socket by a device equipped with a plug to be inserted into the output socket.

Standard:
IEC 60884-1 (GB/T 2099.1) “Plugs and socket-outlets for household and similar purposes – Part 1: General requirements” Clause 14.23.2
IEC 60335-1 (GB/T 4706) “Household and similar electrical appliances – Safety – Part 1: General requirements” Clause 22.3
IEC 62368-1 (GB/T 4943.1) “Audio/video, information and communication technology equipment – Part 1: Safety requirements” Clause 4.7 
IEC 60065 (GB 8898) “Audio, video and similar electronic apparatus – Safety requirements” Clause 15.4.1 Figure 11

Specification:
• Types of sockets: One of each universal socket (suit for GB and BS plug), UL socket, European socket.
• Weight configuration: 1N, 1.25N, 2.5N each 1pc.

Test Process:
1. Adjust the test weight on the right side of the device, and move its left edge to 10mm the steel ruler. And then adjust the balance weight on the balance arm, that is the left side of the device to make the ruler horizontal, and then observe whether the level gauge on the ruler arm is horizontal (observe the level bubble on the ruler).

2. Insert the sample plug into the clamped power socket; adjust the position of the weight on the right of the device. So that the plug-in surface is in a vertical position (observe the level bubble on the ruler). 

3. Read the value on the ruler and multiply it by the weight of the weight. The value is the torque applied by the sample to the power socket. You can also place a 2.5N weight 100mm from the starting point of the balance arm (the left edge of the test weight on the right side of the device is 10mm from the ruler), and observe the state of the ruler to determine whether the torque applied by the sample is within the standard range.
