JIS K 7317:2022 ("Plastics — Determination of scratch hardness of specialty films") covers the standard overview, test method, and key points for selecting the right tester. Axis sensitivity of the test equipment is critical for low-load testing from 10 g.

A scratch test evaluates a material's surface strength and scratch resistance by scratching the surface with a hard stylus under a controlled load. This article explains the test process, applications, and recommended HEIDON equipment.

The pencil hardness test evaluates surface hardness by scratching a coated surface with pencils of different hardness grades. This article explains JIS K 5600, the test method, and relevant HEIDON instruments.

Adhesive strength is the resistance force per unit area when an adhesive bond is broken. This article explains measurement methods (tensile, shear, peel) and relevant HEIDON instruments.

Tribology is the science of friction, wear, and lubrication between surfaces in relative motion. This article explains its basics, testing methods, and HEIDON measurement instruments.

Sliding friction force is the resistance force that acts between two surfaces in relative sliding motion. This article explains its principles, factors affecting it, and HEIDON measurement equipment.

Peel strength testing measures the force required to separate two bonded flexible materials. This article explains 90°, 180°, and T-peel methods, relevant standards, and HEIDON instruments.
