Tensile strength (11 videos)

This video is an overview of Mecmesin's tensile testers: MultiTest-i and MultiTest-xt. The top-of-the range MultiTest-i PC-controlled force measurement systems are an ideal solution for tensile testing in QC and R&D laboratories, while the MultiTest-xt tensile testers controlled by a built-in touch-screen console, requiring only minimal operator training are ideally suited to making routine quality control measurements in production areas.

The Mecmesin CrimpTest-1 is a horizontal, motorised wire terminal tester, designed for ease of use, rapid throughput and high duty cycle operation. Rugged construction, simple controls and a clear display make this compact, benchtop unit an ideal quality checking instrument for wire terminal manufacturing equipment, right at the point of production.


A Mytik Combi Cork Tester is used to measure the release torque and extraction force to test standard ISO 9727 of corks and bottle stoppers.   A versatile fixture enables a range of bottle sizes to be fitted to the tester.

A tensile test is conducted using a touch screen controlled MultiTest 25-xt force testing stand on samples to establish elongation under load and breaking strain. Plane grips are used to clamp the sample which is then stretched at 100 mm per minute. The force applied and the elongation of the sample are recorded at up to 1000 times per second. A graph of elongation vs. applied force is viewed to see the test as it is happening. 

A tensile test is performed to test the integrity of beverage basket carriers and cardboard box packaging.  The test ensures optimimum production line efficiency and that consistent standards of packaging quality are maintained. The tests are conducted on a Mecmesin motorised tensile tester combined with a custom-designed vacuum test fixture, to ensure the tests are performed at a consistent speed to gain better accuracy. 

This video shows how testing safety-belts to find their breaking point can be performed using Mecmesin's MultiTest 50-i force testing system. The MultiTest 50-i, is particularly suited to high force testing and can also produce compressive loads. It is capable of producing a tension of 50,000 Newtons while recording up to 1000 measurements per second. 

Tensile testing of surgical glove material is conducted on a MultiTest-i PC-controlled force tester, measuring the maximum tensile strength and elongation at break.  Emperor software controls the test stand, captures the force measurement and plots force and displacement in real time.

Test-to-failure (TTF) testing of embellishments, buttons, ribbons, sequins, diamante etc. that have been attached to textiles is conducted to check that they have been safely affixed so they will not become choking hazards for infants. Mecmesin's test systems and force gauges are used to measure the force needed to pull the embellishments off from the textiles (TTF) to ensure they comply with BS 7907:2007. 

This video shows a car steering rack being tested to see how much force is needed to operate it over its full working range of movement. The average force recorded shows how smooth the rack is when moved from one end of travel to the other. The test is conducted on a Mecmesin 25-i PC-controlled twin column test system, driven by Emperor force testing software. The software records the peak and average force as the steering rack is moved backwards and forwards.

This video shows a MultiTest 2.5-xt measuring the insertion and withdrawal force of electrical connectors.  A custom made fixture holds the male and female connectors while Emperor software controls the movement of the test stand, and records the forces at the requisite points in accordance with test standard BS 5057.
