For global manufacturers, automotive engineers, and procurement teams working with Japanese specifications, securing a is essential for maintaining strict compliance and ensuring component longevity. What is JIS K 6258? | | Apparatus | Ovens
In the automotive, aerospace, and general industrial sectors, rubber components are frequently exposed to liquids such as oils, fuels, solvents, and lubricants. Understanding how these materials degrade—swelling, hardening, or losing strength—is crucial for product reliability. is the Japanese Industrial Standard designed to evaluate this exact performance characteristic.
This standard is a foundational reference for any industry where rubber components come into contact with oils, fuels, chemicals, or water.
| | 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. |
