1. introductions
This rubber tensile stress-strain testing machine is to measure and
determine tensile strength, elongation at break, stress at a given
elongation, elongation at a given stress, stress at yield and
elongation at yield for vulcanized and thermoplastic rubber.
2. test specimen
Dumb-bells or rings specimen can be used to determine the above
properties and dumb-bells are preferable.
Dumb-bell test specimen have the following outline:
Standard thickness of the narrow portion shall be 2±0.2mm for types
1, 2,3 and 1±0.1mm for type 4.
Test length of the specimen see following table:
| Type of test piece | Type 1 | Type 2 | Type 3 | Type 4 |
| Test length(mm) | 25±0.5 | 20±0.5 | 10±0.5 | 10±0.5 |
3. test speed
100mm/min, 200mm/min and 500mm/min. This test machine can set test
speed from 0.01mm/min to 500mm/min freely.
