If you are looking for specific, in-depth technical data on specimen preparation, can you tell me: Which specimen type (1, 2, or 3) are you using? Is your material thermoplastic or vulcanized? | Feature | | ISO 37 | ASTM

The standard allows both. are more common and are preferred for measuring tensile strength, as they ensure breakage occurs in the narrow, parallel part of the sample. Ring specimens are sometimes used for high elongation materials or to avoid the edge effects that can occur with dumbbell samples, but they are generally less common. There are differences in specimen shapes (Dies) and
