•

This consists of a hydraulic cylinder motor with chain and sprocket drive and a table coupled with the

ram of the hydraulic cylinder, mounted on to a robust base. The cylinder and the ram are individually

lapped to eliminate friction. The upper cross-head is connected to two screwed columns which are

An elongation scale with a minimum graduation of 1 mm, is provided to measure the deformation

Tension test is conducted by gripping the test specimen between the upper and lower cross-heads,

Compression, transverse, bending, shear and hardness tests are conducted between the lower cross

The lower cross-head can be raised or lowered rapidly by operating the screwed columns thus

facilitating ease of fixing of the test specimen.

Principal of Operation :

Straining Unit

Load is applied by a hydrostatically lubricated ram. Main cylinder pressure is transmitted to the cylinder of the

pendulum dynamometer system housed in the control panel. The cylinder of the dynamometer is also of self-

lubricating design. The load transmitted to the cylinder of the dynamometer is transferred through a lever

system to a pendulum. Displacement of the pendulum actuates the rack and pinion mechanism which operates

the load indicator pointer and the autographic recorder. The deflection of the pendulum represent the absolute

load applied on the test specimen.

Return movement of the pendulum is effectively damped to absorb energy in the event of sudden

breakage of a specimen.

•

The control Panel consists of a power pack complete with drive motor and an oil tank, control valves a

pendulum dynamometer a load indicator system and an autographic recorder.



Control Panel :

Operation of the machines is by hydraulic transmission of load from the test specimen to a separately housed

load indicator. The hydraulic system is ideal since it replaces transmission of load through levers and knife

edges, which are prone to wear and damage due to shock on rupture of test pieces.

Machine consists of :


Power Pack :

•

Hydraulic Controls :

•

Load Indicator System :

• This system consists of a large dial and a pointer. A dummy pointer is provided to register the

maximum load reached during the test. Different measuring ranges can be selected by operating the

range selection knob. An overload trip switch is incorporated which automatically cuts out the pump

motor when the load range in use is exceeded.

Pendulum Dynamometer :

•

Autographic Continuous Roll Load-Elongation Recorder :

• This unit is of the pen and drum type and is supplied as standard. The horizontal motion of the pen

produces the load ordinate of the diagram and the drum rotation produces the extension ordinates

in the ration of either 1:5 or 1:10.

Accuracy & Calibration :

•

•



Hand operates wheels are used to control the flow to and from the hydraulic cylinder. The regulation of oil flow

is infinitely variable incorporated in the hydraulic system is a regulating valve which maintains a practically

constant rate of piston movement. Control by this valve allows extensometer readings to be taken.

This unit permits selection of favorable hydraulic ratios producing relatively small frictional forces. Pressurized

oil in the loading cylinder pushes up the measuring piston proportionately and actuates the special

dynamometer system. The piston is constantly rotated to eliminate friction. The dynamometer system is also

provided with an integral damper and ensures high reliability of operation. The load transmitted to the

dynamometer is transferred through a pendulum to the load indicator.

AII VERTEX Universal Testing Machines are closely controlled for sensitivity, accuracy and calibration during

every stage of manufacture. Every machine is then calibrated over each of its measuring ranges in accordance

with the procedure laid down in BS : 1610 : Part 1 :1992 and IS 1828 : (Part 1) : 1991.

VERTEX Universal Testing Machines comply with Grade "A" of BS : 1610 : Part 1:1992 and class 1 of IS 1828 :

(Part1) : 1991 An accuracy of + 1.0% is guaranteed from 20% from 20% of the load range selected to full load.

Below 20% of the selected range, the maximum permissible error is 0.2% of the full load reading.

The power pack generates the maximum pressure of 200 kgf/cm2 the hydraulic pump provides continuously

non-pulsating oil flow. Hence the load application is very smooth

• The pendulum Impact Tester Model IT 30 is designed for conducting izod, Charpy test.

• The test methods confirm to BS : 131 : part 4-1972 (amended 15 Aug. 1993)

BSEN : 10045-2 : 1993 & ASTM : E-23-94a.

• The Pendulum is mounted on antifriction bearings. It has two starting positions, the upper one for Charpy

& the lower one for izod testing.

• On release, the pendulum swings down to brake the specimen and the energy absorbed in doing so is

measured as the difference between the height of drop before rupture and the height of rise after rupture

of the test specimen and is read from the maximum pointer position on the dial scale.

• It is read on digital readout in case of electronic machines.

• There are two strikers and one combined support available for lifting in to the pendulum and on to

the base of the machine for Izod. Charpy test, Changing from one striker to another is achieved simply by

fixing the new striker into it's position.

Portable Barcol Hardness Tester VBH-2

OVERVIEW :

•The Barcol Hardness Tester is a convenient tool for testing the hardness of aluminum, aluminum

alloys, copper, brass and other materials including plastics, fiberglass & FRP having hardness

from 25 to 150 BHN (10 mm ball / 500 kg load).

•The

FEATURES :

TEST PROCEDURE :

• The specimen is placed under the indentor of the Barcol hardness tester and a uniform pressure

is applied to the specimen until the dial indication reaches a maximum.

• The depth of the penetration is converted into absolute Barcol numbers.

Can be used in accordance with:

BS – 2782

NFP 38 – 501



ASTM B 648

ASTM D 2583

• No experience required.

• can be used in any position and in any space that will allow for the operator's hand.

• The hardness reading is instantly indicated on the dial, which is divided into one

hundred graduations.

• No waiting, pre-loading or separate measurements.

PORTABLE HARDNESS TESTER

OVERVIEW :

• 'DT' Portable Rockwell Hardness Tester is developed to meet the demands of a light weight instrument

which can be used to carry out tests by a universally recognised method of Hardness testing.

ROCKWELL METHOD :

• This hardness tester can be used in variety of applications and is readialy adjustable to a wide

ange of sizes and shapes which are difficult to test in a standard table model hardness tester.

• he machine is designed for carrying out Rockwell tests comparable to table model hardness tester because,

the basic things, such as shape of penetrator, method of penetration, measurement and loads

are same in both systems.

• The photograph on the back side gives the general arrangement of the hardness tester.

• The system carries a weight bar (8) pivoted at central point.

• When the load is applied by the loading screw (9), at one end of this weigh bar, it is deflected and the other

end of this bar carrying penetrator forces down into the test specimen.

• Besides this loading dial indicator, here is one penetration measuring indicator (14) which measures the

actual penetration of the penterator into the test specimen is read directly on this indicator.

• The frame carries two adjusting screws and gear train. By rotating the knurled knob the distance between

the penetrator and the support-anvil can be adjusted

METHOD OF

1) Select proper penetrator

2) Take precaution so thet the penetrator does not project beyond the Upper clamp (1).

For this, the loading screw (9) should be sufficiently taken back.

3) Place the test specimen securely on suitable anvil (3).

4) Clamp test specimen firmly between upper clamp (1) and support anvil (3) by rotating the

knurled knob (5) on the lower clamp (2). DO NOT APPLY EXTRA PRESSURE.

5) Check zero setting load indicator(11). Rotate bezel to bring pointer over small black dot for zero load.

6) Apply 10 kgf (98.07 N). major load by rotating the load screw (9) in clockwise direction such that the pointer

on the load indentor (11) comes on set position.

7) Check zero setting of penetrator indicator (14). Rotate bezel to bring pointer to ‘O’ on the black scale.

8) For ‘C’ scale use diamond penetrator against load of 150 kgf (1471 N) and for ‘A’ scale use same

diamond penetrator against a load of 60 kgf (588.4 N).

For ‘B’ scale use 1/16 ball penetrator against a load of 100 kgf (980.7 N).

9) Take off major load by turning the loading screw in anticlockwise direction, such that only minor

load of 10 kgf. (98.07) remains in action – (pointer back to ‘set’ position).

10) Hardness value in Rockwell scale is directly indicated on the penetrator indicator (14).

Read of number on black scale is diamond penetrator.

Read off number on red scale is ball penetrator

• This deflection of weight bar which is proportional to the applied load is indicated on the loading dial
