Name: Pencil Hardness Tester
Category: Lab testing device
Model: KPHT
Feature: To determine the resistance of coating materials or lacquers to scratch effects on the surface
Overview
The purpose of pencil hardness testing is to determine the resistance of coating materials or lacquers to scratch effects
on the surface.
This test is of particular value for furniture or vehicle lacquers, but is also a useful aid in the development of synthetic resins or other film forming materials. Generally, scratch hardness is measured by moving a sharp object under a known pressure over the test surface.The result may either be the value of the pressure required to scratch through the test material if a scratching tool of
constant hardness is used, or the hardness of the scratching tool is varied while constant pressure is applied.
Technical Parameter
1. Twenty mistubishi pencils, grade 9B to 9H(ISO 15184 / BS 3900 - E19) are used with a standard holder
2. Pencils are moved with a fixed pressure (500g/750g/1000g)and a fixed angle ensuring the least amount of operator error.
3. Pencils can be easily exchanged to minimize down time during the test
4. Complies with ASTM D3363, ECCA-T4-1, BS 3900-E19, ISO 151.
Product Application
It is applied in the industry of coatings, paint, inks, pigment, petrochemical, pharmaceutical, food and fine chemical industries.
