The final digit indicates the material's resistance to permanent deformation under a constant compressive load at elevated temperatures. A lower compression set value implies a higher-quality sealing material. Common JIS K 6380 Material Callouts
It ensures that a rubber sheet purchased from different suppliers meets identical physical performance thresholds.
It helps engineers select the exact elastomer needed based on environmental factors like oil resistance, heat exposure, and mechanical stress. Understanding the JIS K 6380 Classification System
Severe oil resistance (low volume swell, typical of Nitrile or Fluoroelastomers). 3. Hardness and Tensile Strength
The standard breaks materials into types: jis k 6380 pdf
The most reliable way to purchase the standard is through the official sales platforms of the JSA or its authorized partners:
Pulling dumbbell-shaped specimens to measure ultimate tensile strength and stretch limits.
The standard specifies the requirements for materials used to prevent leakage between static mating surfaces. It classifies gasket sheets based on their composition (e.g., asbestos-free, synthetic rubber, or fiber-reinforced) and defines their physical properties, including:
To fine-tune a specification, JIS K 6380 utilizes suffix letters and numbers to dictate specialized testing requirements: Heat aging resistance B: Compression set resistance E: Fluid/Oil resistance F: Low-temperature resistance J: Ozone or weather resistance The final digit indicates the material's resistance to
If your product touches any of these sectors, purchasing the PDF is a non-negotiable step.
Baking the rubber in an oven to evaluate how hardness, tensile strength, and elongation degrade over time under thermal stress.
The standard specifically targets vulcanized and thermoplastic rubber compounds engineered for structural sealing, gaskets, and industrial protective sheeting.
Testing methods for these materials are defined by related standards such as JIS K 6251 (tensile stress-strain) and JIS K 6253 (hardness). Classification System It helps engineers select the exact elastomer needed
The Jis K 6380 pdf standard is crucial in ensuring the quality and safety of acrylic rubber products. Acrylic rubber is widely used in various industries, including automotive, aerospace, and construction, due to its excellent heat resistance, oil resistance, and flexibility. However, the presence of residual monomers in acrylic rubber can affect its performance, durability, and environmental sustainability.
Offers detailed standard histories and documentation for industrial users. JIS K 6380:1999 Rubber packing material - Intertek Inform
Following the hardness designation, the code specifies the minimum tensile strength (measured in MPa or kgf/cm²) and the minimum elongation at break (expressed as a percentage). This ensures the rubber sheet can withstand physical stretching and mechanical stress without tearing. 4. Suffix Requirements (Environmental Testing)
: General purpose, often used for water service and waterproof seals. Chloroprene (CR) : Offers balanced chemical, weather, and heat resistance. Nitrile (NBR) : Especially excellent for oil resistance. EPDM (EPT) : Known for superior weather and ozone resistance. Functional Property Codes
