PRS-ZE1500 Pinhole Test Apparatus
PRS-ZE1502 PVC Tubing Ã? 10x8 mm 10 m Coil
STANDARDS : BS 1377:5; ASTM D4647
Water flowing through fine-grained soils with high sodium content makes them highly erodible.
The PRS-ZE1500 Pinhole Test Apparatus is used for evaluating the erodibility of clay soils by flowing water through a small hole that is drilled through the compacted specimen.
The apparatus consists of a cylindrical metal container fitted one end with a water inlet and the other end with an outlet connection, a standpipe tube with scale and a stand to support the apparatus.
Dimensions 150x200x1200 mm
Weight (approx.) 3.5 kg
It is used to evaluate the resistance tracking performance of solid insulating material surface under the combined influence of electric field and humid or contaminate medium. Sum up,it is used to measure the compare tracking index (CTI) and electrical resistance index (PTI).
METHOD OF APPICATION: * Mastic compound application consist of two coats of. Primer ,Primer and followed by Mastic compound in recommended thickness, ranging from min. 12mm to 25mm in one or two layers to achieve desired thickness without any pin hole and crack. 1). Surface preparation and application of Primer: Refer application method of Primer. 2). After doing necessary surface preparation and application of primer coating, area to be installed with Mastic compound should be divided in to equal no. bays. To maintain even thickness required, place wooden or aluminum batten. Mastic compound is then broken in small pieces and put it in heating pan. While heating, keep material moving to avoid burning. It is heated until it comes in a uniform consistency and then applied on the surface and works it with wooden float, to achieve uniform thickness and smooth surface free from any pinholes. CHEMICAL RESISTANCE PROPERTIES: * Mastic compound has good resistance to weak, diluted acids, alkalis salts etc. It is not recommended to use against strong acids, oxidizing acid solvents, oil and fats STORAGE & PACKING: * Keep Mastic compound away from direct sunlight, heat solvents etc. Under this condition, its shelf life is unlimited. It is supplied in cake form and approx. wt. is 10 kgs. HEALTH & SAFETY: * Handle melted Mastic compound compound very carefully . Avoid contact with skin. It is advisable to wear protective wears at the time of use of Mastic compound and all other our products. This information, given in good faith, is based on results gained from experience and tests. However, all recommendations or suggestions are made without guarantee since the conditions of use are beyond our control.

Conforms to is: 10050-1981, & astm d 4644 This apparatus is used to assess the resistance offered by a rock sample to weakening and disintegration when Subjected to drying and wetting in a slaking fluid, usually water. The equipment meets the essential Requirements of is:10050 -1981 & astm d 4644 and comprises the following: A motor drive with reduction gear mounted on a base board and capable of rotating four drum assemblies at a Constant speed of 20 rev/min approximately. The motor drive is totally enclosed in a hinged cover for quick Accessibility. An operating switch is provided in the cover. Two / four test drums made of brass wire mesh, with one end closed and having a removable cover on the other End. They have suitable couplings for mounting in the perplex water troughs. The drums are 140 mm in diameter And have an unobstructed length of 100 mm. Two / four perplex water troughs, accommodate one test drum each. These drums carry quick couplings on either End which are in turn coupled with couplings of the motor drive. The troughs allow 40 mm unobstructed clearance Below the test drum. A water level mark is provided in each water trough 20 mm below the axis of rotation of the Drum. Suitable for operation on 220 volts, 50 hz, single phase ac supply.

Brazilian test apparatus It is also called rock tension testing machine. Brazilian test is a test for indirect measurement of tensile strength of rocks. The instrument is useful for testing specimen from 50 mm dia to 100 mm dia and of thickness of half the diameter. The specimen is held in circular jaws, this is primarily similar to a compression machine and consists of a small load frame having sturdy base with two vertical threaded rods and an adjustable cross head. The hydraulic jack is fitted at the centre of the base of the load frame. The jack of the load frame is self retracting and two plain plates are supplied. A pressure gauge capacity 0-200kn x 2 kn is fixed at the base of jack. A maximum pointer is also provided on the gauge, a pair of semi circular platen for 50 mm dia samples also provided. This instrument can be used in field also. Supplied complete with the steel balls. Order code Product Lisc-563 Brazilian test apparatus with 50 mm dia jaws
This method is used for determining the ductility of bituminous / asphaltic materials by measuring the elongation before breaking when two ends of a briquette specimen are pulled apart at a speed of 50mm/min ±25mm per mount at a temperature of 25c ± 0.50c. Specifications: The apparatus consists of a water bath with a digital temp. Controller cum indicator, and a circulating pump to maintain uniform water temperature. One half of the briquette moulds is fixed on a fixed plate in the water bath, the other half of the briquette mould is fixed to a carrier which slides over a rotating threaded shaft with a clutch. The motor and gears to rotate the shaft are housed in a cabinet fixed above the other end of the bath. A Pointer fixed to the carrier moves over a scale graduated from 0-110 cm x 1mm fixed on the bath with “0” (zero) of the scale towards the fixed plate side. The rotating shaft has 2 speeds of travel for the bracket, 5cm/min and 1 cm/min. Selected by a clutch. Water bath inside is stainless steel with an insulation and a water drain. A heater with digital temp. Controller cum indicator is fixed inside the water bath. Control switches for motor, stirrer, heater and indicator lamps are fixed at a convenient place on the water bath. Supplied complete with three ductility moulds and one base plate. Operates on 230 volts a.C. Single phase.
The plugs are subjected to a compression test at the apparatus, the temperature of the pressure plate, of the base and of the specimens being (23 2) c and the force applied being 300 n. Plywood 60kg 400mmx300mmx600mm
SCR Electroniks make, Shutter Socket Test Apparatus is designed to carry out Socket Shutter Test¦. The apparatus is designed & manufactured exactly as per the IEC & IS Specifications Test Apparatus consists of following parts : 1) Motor to achieve 20 cycles / minutes speed D.C. Motor of suitable is used. 2) Mechanical Assembly : Consists of following parts : Test Plate & Test Plate Mounting Block : On Test Plate socket under test is mounted. Test Plate is in turn mounted on two Mounting Plates with provision for lateral position adjustment. to take care pf different thickness sockets.
