FAQ

What is the pencil scratch method used for?

The pencil scratch method measures coating hardness by applying graduated pencils from soft to hard (e.g., 4B to 6H) to determine resistance to scratching, providing a standardized way to assess durability in industrial applications.

How do I calibrate the tester for accurate results?

Calibration involves ensuring the three contact points align at a 45-degree angle on a flat surface; follow the manufacturer’s guidelines in the manual and use standard test pieces to verify consistency before each use.

Can this tester be used on curved surfaces?

It is primarily designed for flat or slightly curved specimens; for best results, use on smooth, even surfaces as specified in standards like GB1279-79 to avoid inaccurate readings.

What materials are compatible with this hardness tester?

It works well on coatings applied to metals, plastics, and woods, as long as the surface is prepared according to standard methods to ensure reliable hardness evaluation.

How many specimens should I test for average hardness?

Test at least three specimens in different locations and calculate the average to account for variations, as recommended in the product guidelines for consistent quality control.
