Water Vapor Absorption Tester
Water Vapor Absorption Tester Model HV-EXP5832
Water Vapor Absorption Tester - The weight of water vapours absorbed by a sample of leather is determined by fixing a circular piece of leather over a cylindrical cavity in a metal container having distilled water inside it. The test specimen is held firmly against the lip of the cavity and allowed to come in contact with the vapours left off by the water for a specified period of time. The gain in weight of the test specimen because of absorption of vapours by it is determined, from which the value of Water Vapour Absorption is calculated. &civil lab equipments manufacturers.

Vamp Flex Tester Low Temperature Model Model HV-EXP5801
Vamp Flex Tester Low Temperature Model - The Vamp Flex Tester is used for assessing the tendency of shoe uppers and lining materials to crack or fail at the flexing creases formed in the upper during walking. & In this test, square shaped test specimens are held at their opposite edges in two inverted V-shaped clamps having their holding faces in the same plane. One of the clamps is kept fixed while the other is made to move towards it and back repeatedly, producing cracks similar to those formed in the vamp of the shoe. This process is repeated continuously and the condition of the test specimens checked after different specified number of flexing cycles till failure occurs. For conducting resistance to hydrolysis the test specimens are conditioned in saturated water vapour atmosphere by keeping them in a dessicator above water for seven days at 70°C, followed by conditioning under a standard temperature for 24 hours before conducting the flexing test at -5°C. civil lab equipments manufacturers.

Vicat Softening Point Apparatus High Temperature Model HV-EXP4395
Vicat Softening Point Apparatus High Temperature - Vicat softening temperature of plastics is the temperature at which a standard flat-ended indentor penetrates 1 mm into the surface of the material under test under a specified load. The test is conducted by placing a test specimen taken from the sample under test on a flat platform inside a liquid bath and applying compression load over its upper face through a flat-ended indentor. The load is applied by placing dead weights on the upper end of the indentor. After the test specimen attains the temperature of the bath, the bath temperature is increased gradually till the indentor penetrates by exactly 1 mm into the test specimen. The bath temperature in degrees centigrade at which this happens is reported as the Vicat Softening Temperature of the sample under test. & The& Vicat Softening Temperature Apparatus for plastics consists of a hinged metallic frame which serves as support for the test specimen. The frame is fitted with a bush for guiding a rod with a hardened indenting tip at its lower end and a loading platform near its top to place the weights on. A dial gauge is fitted at the upper end of the frame to measure the movement of the rod. The parts that are immersed in the bath during the test are made from brass. The indentor is made from high speed steel. civil lab equipments manufacturers &. Plastic Films Testing Lab equipment manufacturers,exporters and Plastic Films Testing Lab suppliers

Pilling Tester
Pilling Tester Model HV-EXP4382
Pilling Tester - Pilling Tester is a fabric surface fault characterized by little pills of entangled fibres clinging to the surface. These are formed during wearing or washing by the entanglement of the loose fibres, which protrude from the fabric surface, and development of these into spherical bundles anchored to the fabric by a few unbroken fibers. These give a very unsightly look to the garments. & To determine the tendency to form pills, test specimens taken from the fabric sample are rubbed against each other under controlled conditions and the appearance of the test specimen after rubbing for the specified period is compared against standard rating photographs for grading the fabric under test. & Technical Data Inside dimensions of wooden boxes : 225 x 225 x 225 mm & Thickness of cork lining :3 mm & Speed of rotation of boxes : 60 rpm & Dimensions of rubber tubes : 32 outer diameter 25.5 inside diameter 140 mm length & Motor :frac14; HP, single-phase, 230 volts AC & Counter : 5 digit pre-set type electronic counter.
