These materials are categorized into types and classes based on the specific physical properties mentioned above, allowing designers to select the right material for their operating environment. Importance of JIS K 6380 Testing Methods
This structured approach allows any supplier or engineer to immediately understand the material's capabilities without ambiguity.
: Materials are often tested and coded for specific high-performance features: : Heat aging resistance test. : Compression set resistance test. : Oil resistance test. : Ozone resistance test. : Electrical insulation test. : Low temperature test. Constructional Specifications jis k 6380 pdf
First and foremost, it's essential to clarify what JIS K 6380 actually regulates. The standard officially titled "Rubber vulcanizates for packing and gasket — Classification of physical properties," applies to the rubber materials used in a wide array of industrial products.
| JIS Symbol / Applicable Number | Material Type | Key Properties | Source | | :--- | :--- | :--- | :--- | | BFC60584 | | Excellent oil resistance, designed for applications requiring high resistance to various oils. | | | BC7453 | (耐候用 / Weather-resistant) | A weather-resistant material with a hardness of 70±5, a minimum tensile strength of 10 MPa, and a minimum elongation of 250%. | | These materials are categorized into types and classes
is a standard published by the Japanese Standards Association (JSA). It specifies the classification system and physical properties of non-reinforced rubber sheets. Why Use JIS K 6380?
The standard dictates specific test methods to ensure consistency and reliability. Key testing methodologies include: : Compression set resistance test
70 Shore A hardness, high tensile strength, and excellent elongation.
The JIS K 6380 standard is available in PDF format from various sources, including:
The materials classified under JIS K 6380 are essential components in a vast range of industrial products and machinery. Their primary role is to prevent leaks, maintain pressure, and block contaminants. Common applications include:
It typically does not cover sponge (cellular) rubber, ebonite, or O-rings.
