The test method involves preparing a test specimen consisting of a vulcanized rubber layer bonded to a substrate material. The test specimen is then subjected to a tensile test, where the rubber layer is pulled away from the substrate at a specified angle. The force required to separate the rubber layer from the substrate is measured, and the adhesion strength is calculated.
: JIS K 6258 frequently references other standards for specific measurement procedures, such as JIS K 6251 for tensile testing and JIS K 6253 for hardness testing.
Practical tip: Search the JISC catalog using the standard number; if an English translation exists it will be indicated. If you have a standards subscription at work (IHS, Techstreet, SAI Global), use it.
