Jis K 6380 Pdf
The JIS K 6380 standard covers the following aspects:
defines the performance classes, classification of physical properties, and test methods for rubber packing materials (e.g., sheets, gaskets, seals). It is important to note that this standard generally covers vulcanized rubber materials but often excludes specialized items like cellular sponge rubber, ebonite, or finished O-rings, focusing instead on the raw or semi-finished sheet material. Scope of the Standard
Classified by letters (A through K) based on how much the material swells when exposed to specific reference oils. Grade Numbers:
When purchasing or downloading the document, always check the revision year (e.g., JIS K 6380:2014) to ensure you are working with the most current addendums and test methodologies. jis k 6380 pdf
Under the active revision, rubber packing compounds are defined by a multi-part alphanumeric designation. This string provides immediate insight into the material's exact performance limits.
These digits specify the hardness and tensile strength requirements. Suffix Requirements:
Example Code: B C D │ │ │ │ │ └─── Cold Resistance (D) │ └───── Oil Resistance (C) └─────── Heat Resistance (B) I. Heat Resistance (First Character: A to K) The JIS K 6380 standard covers the following
When evaluating a material sheet against a , it is crucial to note the revision date.
Classified by letters (A through J) based on the material's ability to withstand sustained high temperatures. Class (Oil Resistance):
The first three alphabetic characters define the core environmental limits of the rubber sheet: Grade Numbers: When purchasing or downloading the document,
: The active version. It streamlined the alphanumeric classification system to focus more clearly on standalone performance characteristics. Additionally, following a legal revision in 2019, the overarching title of the system transitioned from "Japanese Industrial Standard" to "Japanese Industrial Standard" (日本産業規格) . 3. The Performance Classification System (3-Letter Code)
: Standards are periodically reviewed and updated. Ensure that you have the most current version of a standard, as outdated versions may contain requirements that have been superseded.
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
The standard provides a systematic way to categorize rubber materials based on their physical characteristics. Key elements found in the document include: GlobalSpec Scope and Exclusions
