("Rubber, vulcanized or thermoplastic - Determination of the effect of liquids") specifies methods for assessing the resistance of vulcanized or thermoplastic rubber materials to the action of liquids.
: Calculating the percentage change (swelling or shrinkage).

Using swelling tests (often in toluene) to estimate rubber crosslinking density via the Flory-Rehner equation. Test Parameters and Specimens
: Calculated via analytical balances accurate to 1 mg.
Tracks changes in length, width, thickness, and total surface area.
After the specified duration, the specimens are removed. Technicians rapidly cool them (if tested at high temperatures), rinse or blot away excess surface liquid, and immediately measure the changes in mass, volume, physical dimensions, and tensile properties against their baseline pre-test values. JIS K 6258 vs. ISO 1817
JIS K 6258, titled "Rubber, vulcanized or thermoplastic — Determination of the effect of liquids," specifies methods for measuring changes in the properties of rubber before and after immersion in test liquids. It is largely aligned with the international standard .
