As with all standards, JIS K 6258 undergoes periodic review and revision. The current active version of the standard is , which was published on August 22, 2016. This is the version you should obtain for all current testing and compliance activities.

You cannot substitute ASTM D471 for JIS K 6258 if your customer explicitly requires the JIS standard. The slight differences in volume swelling calculation could lead to a failed approval. You need the exact JIS K 6258 English PDF.

The geometry, thickness, and preparation of the rubber specimens are strictly regulated. Typically, sheets of vulcanized rubber are cut into precise shapes (often rectangular or dumbbell-shaped) to ensure uniform liquid absorption. 3. Immersion Parameters

Measures how much fluid the rubber has absorbed, or how much soluble matter has extracted out of the rubber. jis k 6258 english pdf

Understanding JIS K 6258: The Standard for Testing Rubber Liquid Resistance

The standard provides a detailed methodology for evaluating how vulcanized and thermoplastic rubbers change when immersed in liquids. These liquids typically include: As with all standards, JIS K 6258 undergoes

: Tracks post-immersion changes in tensile strength, elongation, and hardness. 2. Key Differences Across Standard Revisions

Measuring the weight before and after immersion.

Only one surface of the test piece is exposed to the liquid (used for special applications like diaphragms or liners). B. Parameters Measured Change in Mass ( ): Increase or decrease in weight. Change in Volume ( ): Swelling or shrinkage. Change in Dimensions: Thickness, length, and width changes. You cannot substitute ASTM D471 for JIS K

Ensure the document is translated by an authoritative body to avoid errors in critical unit conversions or technical terms.

Evaluates how much mechanical structural integrity the rubber retains after chemical exposure.

The test measures changes in physical properties after immersion, such as:
