JIS K 6380 - Rubber Packing Material - Standards | GlobalSpec

The JIS K 6380 standard, titled "Rubber Packing Material", provides a classification system for the physical properties of rubber materials used for industrial packing.

While the standard itself outlines performance requirements, it relies on other specific JIS standards for the actual preparation of test pieces. To prepare a piece according to JIS K 6380 requirements, you must follow the general procedures for vulcanized rubber. Core Reference Standards for Piece Preparation

To prepare a test piece correctly, the following standards are typically cited within JIS K 6380:

JIS K 6250: The primary standard for general procedures for preparing and conditioning test pieces for physical test methods.

JIS K 6251: Specific guidelines for preparing pieces to determine tensile stress-strain properties (often using "dumb-bell" shaped cutters).

JIS K 6253: Procedures for preparing samples for hardness testing (IRHD or Durometer methods). General Preparation Steps

Based on industrial practices for these standards, here is how you generally prepare a piece:

Material Conditioning: Before cutting, the rubber sheet should be conditioned at a standard temperature (typically ) and humidity for at least 16 hours.

Cutting: Use a standardized cutter (die) to punch out the required shape from a flat rubber sheet. For tensile tests, this is usually a No. 3 or No. 5 dumb-bell shape.

Thickness Measurement: Measure the thickness of the prepared piece at multiple points using a calibrated micrometer to ensure it falls within the specified range (often for standard sheets).

Marking: For elongation tests, apply "bench marks" (reference lines) to the narrow section of the dumb-bell using an ink that does not damage the rubber.

Surface Inspection: Ensure the piece is free from visible flaws, air bubbles, or ragged edges from the cutting process, as these will lead to premature failure during testing. Standard Resources

Official copies of the standard can be purchased or previewed through the Japanese Standards Association (JSA) or Intertek Inform.

Technical excerpts for specific materials (like CNR or NBR sheets) are often provided by manufacturers such as Togawa Rubber or Tigers Polymer.
