, though it contains specific modifications tailored to Japanese industrial requirements. Intertek Inform Core Objectives & Measured Properties

Stress measured at specific elongation levels (e.g., 100% or 200% stress). Yield Point:

It defines standard methods to measure how rubber materials behave under tension until they reach their breaking point. Key Measured Properties jis k 6251 pdf

The test piece is mounted into the grips of a Universal Testing Machine (UTM). The machine separates the grips at a standardized, constant speed: Typically .

Dumbbell specimens are preferred for absolute tensile data, while ring specimens eliminate stress concentration at clamping points. Specimen Type Common Application Characteristics Universal standard testing , though it contains specific modifications tailored to

If you have landed on this page, you are likely searching for the term . This query is common among quality control managers, rubber product manufacturers, engineering students, and material testing professionals. You need the official document to determine the tensile properties of vulcanized rubber, but finding a legitimate, usable version can be frustrating.

): Often referred to as the "modulus," this is the stress required to stretch the test piece to a specific percentage (e.g., 100% or 300% elongation). Key Measured Properties The test piece is mounted

Insight: While JIS and ISO are nearly identical today, ASTM D412 die profiles (specifically Die C) are slightly different. This can result in slight variations in reported tensile strength due to stress concentration differences in the narrow section of the specimen.

Avoids gripping errors but creates non-uniform stress distribution across the ring width. The Testing Procedure

Ensure that tests conducted in different laboratories produce comparable, reproducible results. Where to Find JIS K 6251 PDF
