Purpose of Test:<\/strong><\/p>

To evaluate the film hardness of an organic coated steel sheet.<\/p>

Non cured organic coated film has lower pencil hardness and will be damaged even at softer pencil leads<\/p>

A set of calibrated drawings leads following scale of hardness:<\/p>

6B – 5B – 4B – 3B – 2B – B – HB<\/u> – F – H – 2H – 3H – 4H – 5H – 6H
<\/u>Softer\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Harder<\/span><\/p>
