The standard specifies the test methods for measuring the indentation hardness of rubber using various durometers. It is used to evaluate the stiffness and elastic modulus of rubber materials in a non-destructive manner. Types of Durometers Covered

According to JIS K 6253-3, the hardness tester must consist of:

In Japan, and increasingly in global supply chains interacting with Japanese manufacturers, the standard that governs this critical measurement is the JIS K 6253 series. Specifically, plays a pivotal role in ensuring consistency and reliability.

The standard requires traceable calibration at two points:

The instrument must be capable of measuring indentation depth with a resolution of 0.001 mm.
