A typically includes detailed tables, test method references, and dimensional charts that are indispensable for quality control.
JIS K 6380 establishes a comprehensive classification system for the physical properties of rubber materials used in industrial packings. It serves as a benchmark for manufacturers and engineers to ensure material consistency and performance across various applications, ranging from simple buffers to complex chemical-resistant seals.
Indicates the minimum allowable tensile strength in Megapascals (MPa), validated via JIS K 6251 . jis k 6380 pdf
The current active edition significantly altered the naming syntax. It introduced a flexible coding structure based on basic performance, physical properties, and additional specialty designations to match evolving industrial demands. 2. Deciphering the JIS K 6380 Classification Code
. It specifies the requirements for rubber sheets and molded products used primarily for gaskets and seals. Tiger Asian Trading Key Features and Classifications Excellent for outdoor weathering
Utilizing a Type A durometer to ensure the sheet meets the specified stiffness.
Determining the breaking point under tension. A typically includes detailed tables
Follow these steps to legally acquire a :
Classified under high temperature and low oil-resistance codes. Excellent for outdoor weathering, steam, and automotive cooling systems.
: Maximum stress the rubber can withstand while being stretched. Compression Set
Determined using a 72-hour forced-air aging test matching JIS K 6257 protocols. It measures the maximum operational testing temperature at which tensile and hardness changes remain within strict thresholds: Base room temperature testing / unregulated B: 100°C C: 125°C D: 150°C E: 175°C F: 200°C 2.
