Tensile Strength Tester

Tensile strength testers are equipment used to test the tensile strength of specimen of different semi-products and products. The test can be on a conducted on a variety of materials including metals, plastics, elastomer's, paper, composites, rubbers, fabrics, adhesives, films, etc. A particular tensile strength tester can be chosen depending on the material requirement and need of test. The equipment comes complete with arrangement for motorized loading and come in mechanical as well as digital models.

Tensile strength testing is done to test and evaluate the behavior of a sample while an axial stretching load is applied. Tensile strength tests can be executed under the conditions of ambient or controlled temperature to determine the tensile attributes of a material.

Testing Results
Tensile testing is generally used to determine the maximum load (tensile strength), which a material or a product can withstand. The test may be based on a elongation value or load value. Some of the common tensile testing results are -

• Maximum Load
• Deflection of Maximum Load
• Work at Maximum Load
• Stiffness
• Load at Break
• Deflection at Break
• Work at Break
• Chord Slope
• Stress
• Strain
• Young's Modulus

Advantages
By determining the tensile strength of a filter media, the expected life of a HEPA can be estimated. The operational life can be determined on the basis of observed decrease in the tensile strength of dry filter media with age and any further reduction in strength due to exposure to water. Although the life of a filter cannot be directly estimated using the data, there is a substantial decrease in the tensile strength with age for unfolded as well as folded media.
