Measuring how much a material swells or shrinks (volume change). jis k 6258 english pdf
: Testing tensile stress-strain properties and hardness after immersion.
The "English PDF" version of JIS K 6258 details several physical properties that are measured before and after immersion: Mass and Volume Change
To understand what you're looking for, it is helpful to know the exact scope of this standard. is the most recent version of this document, titled "Rubber, vulcanized or thermoplastic — Determination of the effect of liquids." Industrial standards are protected by copyright laws
A significant point of confusion arises from the standard's history. The code "JIS K 6258" has been in use for decades, but the document has undergone several revisions. It is vital to ensure you have the correct and most current version.

Testing technical rubber parts like conveyor belts and seals exposed to crude oil. GlobalSpec Core Testing Methods
Designed explicitly for modern multi-layered hoses, coated fabrics, or localized structural diaphragms. Specialized testing apparatuses isolate only a single surface area face to evaluate structural degradation and fluid migration performance under localized contact conditions. 3. Standard Test Liquids
JIS K 6258 standard is a critical document for engineers and manufacturers working with vulcanized or thermoplastic rubber. It specifies the testing methods used to determine the effects of liquids—such as oils, fuels, and chemicals—on rubber materials.
The standard is a critical framework published by the Japanese Standards Association (JSA) for evaluating how vulcanized or thermoplastic rubber behaves when exposed to liquids. Officially titled "Rubber, vulcanized or thermoplastic — Determination of the effect of liquids," this standard dictates the exact lab testing methodologies used to measure changes in mass, volume, dimensions, and mechanical properties of rubber materials before and after chemical immersion.
