JIS K 6258 is a Japanese Industrial Standard titled "Rubber, vulcanized or thermoplastic – Determination of the effect of liquids." It is technically identical to the international standard (formerly ISO 1817:2015, with periodic updates). The standard specifies methods for measuring the change in physical properties of rubber after immersion in test liquids—such as oils, fuels, acids, and chemical solvents.
One of the primary tests in this standard is the determination of solvent-extractable matter.

The rubber absorbs the test liquid, causing physical swelling, softening, and reduced tensile strength.

The standard dictates strict protocols for how a rubber sample must be prepared before chemical analysis. This usually involves grinding the rubber to a specific particle size to ensure that solvents can effectively penetrate the material during extraction processes. JIS K 6258 references the preparation methods often found in related standards (like JIS K 6250) to ensure uniformity.
