Peel Fixture for Yoghurt Pot Foil Lids

This custom designed fixture consists of an angled platform that can slide along the base plate and be locked into position by thumb screws to enable the edge of the foil lid of the container to be positioned on the machine centre line. A fully adjustable clamping arm, which can move vertically and horizontally according to the sample size, secures the container at the predetermined angle on the testing platform.
A top fixture (Model GF-11), connected by a non-elastic cord to the upper boss on the testing machine, grips the container foil. The machine's crosshead is driven upwards to test the force needed to peel the foil from the container.

Spaghetti and Pasta Compression Fixture

This Spaghetti and Pasta Compression Fixture was custom designed for one of Italy's best-known manufacturers of traditionally made high quality 100% durum wheat pasta. The company wanted a test fixture to evaluate various textural properties of cooked spaghetti under compression, simulating human bite and mouth-feel.
Used in conjunction with a Lloyd Instruments test machine and data analysis/applications software, the fixture was designed to compress a small sample of pasta between two circular compression platens and to measure the thickness at two specified loads. The jig uses the compression plates as a load for compression. Thickness measurements are taken before and after the test to measure the recovery of the sample and to determine if it is a good or bad batch.

The fixture consists of a fixed lower compression platen and a top compression platen attached to the base of a vertical rod which is driven up or down by the system. The effective weight of the top plate assembly is reduced to 15 g using a counterweight, which is attached via a toothed belt. This belt is suspended over two pulleys, one of which is attached to a high resolution encoder. When the top compression plate moves, the encoder rotates to measure the postion of the top compression platen.

90° and 180° Credit Card Peel Jigs

90° Credit Card Peel Jig
The fixture comprises a mechanical self-adjusting sliding bed and an upper vice action grip for clamping the peeled card laminate.
Two razor cuts are scored at a predefined distance about the length of the card centre line. The card is clamped to the test plate on the sliding bed by two rebated bars, locked into position by thumb-screws. A small section of the centre laminate is lifted away from the card and fixed in the upper vice grip. The crosshead of the test machine is driven upwards and the test plate, which can move freely in a horizontal plane, maintains an angle of peel of 90o during the peeling operation.

180° Credit Card Peel Jig
To perform 180° peel tests, Lloyd Instruments has designed a second jig. This fixture comprises a vice action grip fitted to the lower anchor pin and an upper thin plate fitted with a bar and two thumbs screws for clamping the peeled laminate into place.

The razor cuts are scored about the centre line along the length of the card and a section of this laminate is manually lifted. This peeled laminate section is locked against the opposite face of the backing plate using the clamp bar. The card is then swung into a parallel position to the packing plate in the vice action grip.

The backing plate, fitted to the loadcell on the machine's moving crosshead, is driven up by the test machine to perform the 180° peel test on the sample.

Applicable Standards
ISO/IEC 7810 - Identification cards - Physical Characteristics. This standard sets out a range of physical characteristics including the mechanical robustness of the card.
ISO/IEC 10373 - Identification cards - Test Methods. This standard deals with the test methods employed to test credit cards. Flexural tests are applied along both horizontal and vertical axis. Cards are also twisted to see if damage occurs to the laminate.

3 Point Bend Jig for Polystyrene to EN 12089:1997 Method B

3 Point Bend Jig for Polystyrene to EN 12089:1997 Method B

This fixture is designed to perform three point bend tests on polystyrene samples measuring 300 x 150 x 50 mm (11.81 x 5.91 x 1.97 in) in accordance with the standard EN 12089: 1997 (Method B).
The jig consists of an extruded aluminium base with a fixed centre of 250 mm (9.84 in). Two circular supports 30 mm (1.18 in) in diameter, are fitted to the base. The sample is placed centrally on the two supports. An upper loading anvil with a 5/8 in eye end is fixed to the machine's load cell and driven donw onto the sample midway between the two supports.

Applicable Standards
Meets the requirements of EN 12089:1997 Method B

XY Table for Automated Testing to Evaluate the Performance of Rubber Stoppers on Multiple Glass Phials

This computer controlled XY table is designed for repeat automated testing applications.

The table illustrated has been configured to test the performance of rubber stoppers on multiple glass phials via penetration tests using hyopdermic needles. It is fitted to the base of a Lloyd Instruments single column materials testing machine and is fully controlled via a specially written program using NEXYGEN™ MT data analysis software and Ondio™ application builder software.

The XY table is divided into three sections consisting of a quick-change rack which can accommodate up to 40 syringe needles and another for holding up to 40 glass phials each fitted with a rubber stopper. A third section incorporates a removable bin in which used needles are deposited.

An upper pneumatically operated grip is programmed via the software to automatically pick up a hypodermic needle, removing it from its plastic cover. The table is then moved under computer control to correctly position the rubber stopper on the appropriate glass phial under the hypodermic needle to begin the penetration test. This process is repeated using the next needle and the next phial until the tests are completed.

Using NEXYGEN software, there is also the facility for pumping distilled water through the body of the hypodermic needle into the glass phial to enable any rubber residue to be flushed out and measured.

Bollard Grips for Fibre Optic Testing

This pair of bollard grips specifically designed for tensile testing of fibre optic cable up to 5 mm (0.196 in) in diameter.
The cable is wrapped around the bollard and the free end of the sample is clamped firmly in place. This configuration allows grip stresses in the sample to be distributed uniformly around the circumference of the bollard.

Adhesion Test Jig for Torque Testing of Super-Glued Nuts and Bolts

Steel jig for testing the torque of super-glued nuts and bolts.

The glued nut/bolt assembly is clamped into position whilst a lever arm is driven down, applying torque force to the nut. Failure in the adhesive is indicated when the nut moves on the bolt thread (drop in force in the Lloyd Instruments NEXYGENPlus software).

The jig comprises a swivel plate, which can be moved to allow the sample bolt head to be inserted into a slide block. The sample is secured into position by an adjusting screw. A spanner lever, 150 mm (5.9 in) in length and 12.7 mm (0.5 in) wide, is located into the assembly at an angle of approx 45°. The nut is engaged into a special socket mechanism permitting extreme ease of use. The slide block is locked into position using a thumbscrew located under the base plate. A dome-ended probe fitted to the crosshead of the test machine is then driven down onto the lever to apply force to the super-glued bolt assembly, causing the adhesive bond to break.

Peel Fixture for Heat Sealed Plastic Film Covers on Food Containers

This fixture consists of a small upper spring loaded wedge grip to clamp the film container cover, and a horizontal sliding bed fitted with a "dish holder".
A mains operated vacuum pump with associated piping and vacuum control valve is used to apply vacuum to the "dish holder" to retain the food container securely in position during the test. The wedge grip is fitted to the supplied threaded adapter and connected to the upper anchor pin on the loadcell.

The sliding bed fixture is connected to the lower anchor pin. Once the pump is switched on, the food container sample may be positioned in the holder and the vacuum control valve adjusted so that there is sufficient force to restrain the dish when the plastic cover is peeled off. The sliding bed is positioned so that the loose part of the cover is located below the upper wedge grip. By lowering the moving crosshead, so that the wedge grip is just together to open the jaws, allowing the edge of the cover to be positioned into the jaws. The levers may then be released and the test carried out.
