Hardened Steel Pin (Scratch Resistance Pin)
Hardened steel Pin is designed according to IEC60950 clause 184.108.40.206 and IEC60335-1 clause 21.2. It is applied to do scratch test for accessible parts of solid insulation of household appliance and printed circuit boards, to ensure the material has sufficient strength to prevent penetration by sharp implements.
The hardened steel pin should work with abrasion resistance tester. When performing the scratch test, scratches were performed at a speed of 20 mm/s ± 5 mm/s in a plane perpendicular to the edge of the conductor. The steel pin should be properly loaded so that the hardened steel pin can apply a force of 10N ± 0.5N along its axial direction. The pin can equip with 20N weights to reach 30N load.
