The maximum tensile stress recorded executed up to the point of rupture.
The standard prescribes using die-cut specimens shaped either as (the most common) or concentric rings . Dumb-bell specimens ensure that stress concentrates uniformly across the narrow central gauge section, preventing grip-face ruptures. 2. Environmental Conditioning

JIS K 6251 specifies two primary geometries for test samples:
The sample is placed in the grips of a tensile testing machine (instron). Stretching: The machine pulls the sample at a constant speed—usually for most rubber types—until it snaps. 5. Calculation Formula The Tensile Strength is calculated using the formula:
