Complies with standards: GB2099.1-2021 Figure 14 and Clause 14.2, IEC60884-1-2002 Figure 14

Purpose: Used to test the mechanical strength of non-solid pins of portable electrical accessories

Sample scope: Non-solid pins

Structure and function: According to the standard, apply a force with a 100N weight

14.2 Mechanical strength of pins of portable electrical accessories

The pins of portable electrical accessories shall have sufficient mechanical strength.

Compliance is checked by the tests of Chapter 24. For electrical accessories with non-solid pins, the following test is also carried out after the test of Chapter 21.

Using a steel rod with a diameter of 4.8 mm, apply a force of 100 N for 1 min to the pin supported according to Figure 14. When applying the force, keep the axis of the steel rod perpendicular to the axis of the pin.

During the application of force, the reduction in the dimension at the point of force application on the pin shall not exceed 15 mm.

After removing the steel rod, the dimensional change of the pin in any direction shall not exceed 0.06 mm.

Technical parameters:

1. Steel rod: Φ4.8mm;

2. Load weight: 100N;

3. Manually rotate the handwheel to apply pressure on the pin, duration 1min
