IEC61851-1 Standard Test Finger for Verifying the Accessibility to Live Parts of Vehicle Connector
1. Introduction
The standard test finger is designed according to IEC62196-1 for verifying the accessibility to live parts of socket-outlets and vehicle connectors. Meanwhile, it also be called as test probe B or jointed test finger in standard IEC60529 for IP2X testing, which can apply to test the indoor use vehicle connector, EV plug, EV socket as per standard IEC61851-1 clause 12.4.
The standard test finger consists of handle and finger, the handle is made of insulation material, and the finger is made of steel. The finger part consists of 2 joints, then joints can be bent through an angle of 90°. The probe can built-in 10N thruster, so that user can apply force directly during the test. And the probe will come with a lead to allow connect with a electrical indicator to show the contact with relevant parts.

3. Frequently Asked Questions
1). How can we apply force during the test?
Pego: There are two methods for user to apply the force during the test: 1. User can choose the test probe with built-in thruster, the thruster is built-in the handle, just push the handle, the appropriate force can be applied. 2. The probe can work with a force gauge to apply force. The probe configured with a connector at the tail of the handle.
Normally, the recommended force applied to test is 10N, but in some product standards, the recommended force will be up to 50N.
2). How does the probe connect with a continuity indicating circuit?
Pego: The probe will come with a wire to connect with a continuity indicating circuit. User can create a continuity indicating circuit by themselves, or buy aN electrical indicator from Pego.
3). How to store and maintain the test probes in daily life?
Pego: The probes will come with a protective case, When not in use, place it in the case.
