6253-3: Jis K

For engineers, QC professionals, and procurement specialists working with Japanese automotive parts, electronic components, or industrial seals, understanding JIS K 6253-3 is not optional—it is a contractual necessity. This standard, titled "Rubber, vulcanized or thermoplastic – Determination of hardness – Part 3: Durometer method," dictates exactly how to measure indentation hardness using Type A and Type D durometers.

Because Japan is a global leader in automotive, electronics, and precision machinery, JIS K 6253-3 appears in thousands of material specifications. jis k 6253-3

The IRH method measures the of a spherical indentor under a specified contact and indentation force. The hardness value is derived from the difference in penetration depth between a small initial force and a larger total force. The IRH method measures the of a spherical
