The Japanese Standards Association is gradually moving toward a "pay-per-view" digital model, similar to ISO. This means that in the near future, you may be able to rent access to the for a lower fee (e.g., $20 for 24 hours). However, as of today, permanent download remains the only legal option.

For international engineering teams and global supply chains, accessing and understanding the version is essential for cross-border compliance, material selection, and quality control. What is JIS K 6258? jis k 6258 english pdf

The standard provides a structured approach to evaluate how rubber reacts when exposed to industrial fluids like petroleum products, crude oil, and chemicals. Immersion Process: Immersion Process:

.

| | Details | |-------------|--------------| | Scope | Specifies methods to measure changes in physical properties (mass, volume, dimensions, tensile strength, elongation, hardness) after immersion in test liquids. | | Test liquids | Includes reference liquids (e.g., IRM 901, 902, 903 for oils), fuel liquids, and actual service fluids. | | Test pieces | Typically small, cut from rubber sheets using specific dies. | | Immersion conditions | Temperature and time specified (e.g., 70°C for 70 hours, or 100°C for 70 hours). | | Measurements | Mass change, volume swell, change in tensile properties, and hardness change. | | Apparatus | Ovens, immersion vessels (glass or stainless steel), balance, thickness gauge, tensile tester. | | Calculation formulas | Precisely defined equations for percent changes. | | Precision statement | Repeatability and reproducibility values. | | | Apparatus | Ovens
