TG112/LR 01/3277/LR $1,535
Coefficient of Sliding Friction Fixtures
These fixtures consist of a horizontal flat bed incorporating a suitable clamping device and a sled. The
underside of the sled has a layer of smooth-faced foam rubber.

Capacity
100 N, 22.5 lbf
Packaging
Includes test bed, sled, sample fixture and drive cord attachment.
Applications
Used to determine the static and kinetic coefficients of friction of plastic film or paper when sliding the specimen over itself under controlled test conditions. A sheet of the specimen is clamped securely to the horizontal bed and another sample of the specimen is clamped to the underside of the sled. This measures the force required to overcome the frictional resistance between the two imposed surfaces, when one surface is moved relative to the other along their plane of contact. The static coefficient of friction is determined by the force required to overcome the initial resistance between the two surfaces. The kinetic coefficient of friction is determined from the subsequent force when continuously sliding at a constant rate.
Shouldered Grip for Adhesive Test (5 kN, 1124 lbf)
This fixture consists of two bobbin holders with a slot in the shoulder to allow the bobbins to be easily inserted. The adhesive to be tested, is applied to the square surface of each bobbin, then the bobbins are held together until the adhesive is set. The assembly is then slid into the slots of each holder and the tensile test performed. The grip is supplied complete with six bobbins so three tests can be performed in a batch. After each test, the adhesive is removed ready for the next test. Bobbins are also suitable for testing sealants and mastics.
Capacity
5 kN, 1124 lbf
Packaging
Includes upper and lower bobbin holders and six bobbins.
Applications
Used to determine the adhesion properties of adhesives, sealants and mastics by measuring the minimum tensile stress neccessary to detach or rupture the coating.
90° Peel Strength Fixture (200 N, 45 lbf)
This fixture features a self-adjusting sliding bed for 90° peel tests. The test plate moves freely in a horizontal position when the pressure sensitive material is removed in order to maintain a 90° peel angle.
Note: The test plate must be supplied by the customer. The FINAT standard states that plate glass should be used. If stainless steel or aluminium is used as a substitute, it should be stated with the recorded results.
Packaging
Includes upper fixture and lower sliding bed. Does not include test plate. Upper fixture is available separately.
Applications
Used for peel tests on a wide rang eof materials including sealing tape, labels, laminated coatings etc.
Climbing Drum Peel Test Fixture (2.5 kN, 562 lbf)
This peel test fixture consists of a flanged drum and flexible loading straps or cables. A drum clamp is used to securely hold the adherent against the drum face. The drum is balanced about axis using counter weights placed diametrically opposed to the drum clamp to compensate for the clamp mass.
Packaging
Includes fixture and loading straps.
Applications
Used to determine the resistance of joints to perpendicular peel stresses on an adhesive layer. Applicable to the testing of joints between an outer metal sheet and the core of sandwiched assemblies, eg. honeycomb or other forms of composites. The adherents are separated steadily by the action of a revolving drum, which rotates by the application of a tensile force from the associated testing machine.
