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.
You can find the English PDF version of JIS K 6258 through various sources, including:
The primary purpose of this standard is to establish a systematic method to evaluate the resistance of rubber materials when they are exposed to various liquids. This is achieved by immersing rubber test pieces in designated liquids under specific temperature and duration conditions, then measuring changes in their physical and mechanical properties before and after immersion. These changes typically include alterations in mass, dimensions (volume and area), and mechanical properties like tensile strength or hardness.
This is the international equivalent. JIS K 6258 is highly harmonized with ISO 1817, meaning a test run under the JIS standard will yield nearly identical data to the ISO equivalent, provided the same reference oils are used. jis k 6258 english pdf

Unverified downloads frequently bundle malware or distribute outdated, superseded versions of the document (such as the 1993 or 2003 iterations).
Understanding how rubber materials interact with liquids is critical for engineering reliable automotive parts, industrial seals, and chemical hoses. is the Japanese Industrial Standard that defines the testing methods used to determine the effects of liquids on vulcanized or thermoplastic rubber.
cubes for volume tests or "dumbbell" shapes for tensile strength. Revision History You cannot substitute ASTM D471 for JIS K
Updated to align as a modified version () of ISO 1817:2015 . Includes thermoplastic elastomers. 3. Summarized Test Methodology
The standard helps manufacturers, suppliers, and users of rubber products to ensure that the materials meet the required specifications and performance standards. By following JIS K 6258, companies can:
JIS K 6258:2016 outlines standardized methods for testing the effect of liquids on vulcanized and thermoplastic rubber, evaluating changes in volume, mass, and mechanical properties. It is a critical standard for measuring material stability against oils and fuels, closely related to ISO 1817.

"The material isn't the problem," Kenji said confidently. "The gasket is compliant with JIS K 6258. Our acceleration parameters were flawed. If we test according to the standard—specifically section 7.3—we will see the material holds."
Measures the loss of structural rigidity after chemical saturation using durometer scales defined in JIS K 6253 .
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
The standard measures variations in critical physical properties, including: To quantify swelling or shrinkage.
