Double Columns Tensile Testing Machine is computer-controlled and widely used for mechanical performance testing of non-metal materials such as rubber, plastic, wire and cable, textiles, waterproof materials, nonwoven fabrics, as well as metal wires, metal foils, metal sheets and metal bars. It can also be used for various finished product testing, including tensile, compression, peeling, shearing, tearing, and bending (folding) tests, with the help of special fixtures.

It can automatically calculate parameters such as tensile strength, yield strength, elongation, constant elongation stress, constant stress elongation, and modulus of elasticity according to standards such as GB, JIS, ASTM, DIN, etc.

Standard:
DIN EN ISO 7500-1 “Metallic materials – Verification of static uniaxial testing machines – Part 1: Tensile testing machines”
DIN EN ISO 527-1 “Plastics – Determination of tensile properties – Part 1: General principles”
ASTM D3811 “Standard Test Method for Unwind Force of Pressure-Sensitive Tapes”
ISO 1924-2 “Paper and board -Determination of tensile properties-Part 2: Constant rate of elongation method”
ISO 5893 “Rubber and plastics test equipment — Tensile, flexural and compression types (constant rate of traverse)-Specification”

Specifica:
• Force units: N, KN, Kgf, and Lbf can be freely converted.
• Length units: mm, cm, and inch can be freely converted.
• Control modes: Various control modes such as software-set speed, running time, load rupture (fracture), etc, are available.
• Automatic detection of material rupture, compression crush, etc. and automatic shutdown. Automatic return can be set.
• Types of curves: Load-displacement, load-time, displacement-time. Stress-strain, strain-time, stress-time. The coordinates of the curves can be set arbitrarily.
• Standard fixture can measure parameters such as maximum force, minimum force, rupture value, and tensile strength.
• Customized fixtures/extensometers can measure parameters such as compression strength, upper and lower yield strength, elastic modulus, elongation, maximum, minimum, and average.
• Equipped with multiple protections such as overload, overcurrent, overvoltage, undervoltage, overspeed, and stroke.
• It already includes one set of PC which already installed the control software, the software has Chinese, English, Russian and Spanish version.
