Impact Test

This simple to use gauge is ideal for evaluating the resistance of a coating to impact (elongation, cracking or peeling

Standards

ASTM G-14,D2794,IS, DIN,ISO
Specimen Size :0.025 in. or 0.63mm
Indentor size:0.5 in. or 12.7mm
Weight of Tub:1.361 Kg.
Drop range: 0.61 to 1.22m [2 to 4 ft.]
Specimen Size:0.025 in. or 0.63mm

If no cracks are evident, repeat the procedure at a greater height, increasing 1 in. (25mm) at a time.

Pencil Hardness Test

Simple & effective technique to evaluate the hardness and resistance to cratching of coatings

Standards

ASTM D 3363
The Pencil Hardness Tester is a simple and affective technique to evaluate the hardness and resistance to scratching of coatings.
The test method allows the used of pencils which have a known hardness grade to be moved over the surface to be tested at a fixed angle and pressure.
Allows the use of pencils which have a known hardness grade to be moved over the surface to be tested at a fixed angle and pressure

Flexibility Test

Also known as conical mandrel testis a mechanical testerused to determine the effects of bending on the elasticity, adhesion and elongation properties of cured coatings on sheet metal

Standards

ASTM D 522
BS 3900-E11

Cross Hatch Adhesion Test

The Cross Hatch Cutter allows an assessment to be made of the adhesion resistance of coatings to separation from substrates when a right-angled lattice pattern is cut into the coating and penetrates through to the substrate.

Stormer viscometers-(ASTM D 562)

ASTM D 3359
The 1mm Cutter is suitable for coatings under 60 microns.
The 2mm Cutter is suitable for coatings over 60 microns.
Multiple coatings can be tested for the assessment of the resistance to separation of individual layers of the coating from each other.

Scratch Hardness Test

Defined as resistance to indentation or scratching

Standards

ASTM D 2197
BF 3900
D2197
ISO 1518
Range 50 gm to 10 kg
The scratching needle is a hardened steel hemispherical tip of 1 mm dia.
Clam the panel on the DC circuit panel
Place weight on the holder above the needle
Start the motor to make a scratch on the coting
Observed the scratch for penetration upto the substrate
Failure of the coting is the indicated by deflaction in the current needle due to completion of the circuit
A Voltmeter indicates the contact, when the needle touches the base metal. The automatic systems disengage the needle from the panel when returning to home
position. Failure of the coating is indicated by deflection in the current needle due to completion of circuit

SHORE Hardness A & D

Measures the hardness of the surface of the coating.

Standards

ASTM D 2240 ASTM D 2240 Fiberglass, Aluminum,Soft Metals,Plastics,Painted Surface
Take the measurement at last 12 mm form the edge of the material
the material must be at last 6 mm thick
Required pressure must be applied for 15 seconds
This force should be max 4.55 kg for a type D durometer
Meaning of a durometer reading no indent sign :100 If indentation upto:2.5 mm :0
Measurements taken at 12mm from the edge of material
Material must be at least 6mm thick.

Holiday Detector Test

The Holiday Dete ctor is a DC Holiday Tester that tests and detects pinholes and flaws in insulated coatings on conductive substrates.

Standards

ASTM D 4787
ASTM G 62
ISO 2746
BS 1344-11

Significance

Pinholes in coatings invisible to naked eyes./li>
Detector counts pinholes and sounds alarm.
Allows instant repair of pinholes.
Especially suitable for large diameters and enables reliable testing of the complete tube in one or two operations only.

Taber Abrasion Test

Designed to perform accelerated wear tests on a variety of specimens.

Standards

ASTM D 4060

Significance

Wheels shall be 12.7mm thick and have an external diameter of 51.9mm and in no case less than 44.4mm.
Wheels CS-17,10 H-10, 18, 22 & OTHERS

Pull off Adhesion Test

Measures the adhesion bond strength of applied coatings with ease, and precision

Standards

ASTM D 4060
The adhesion is measured by the tensile pull on a Dolly glued to the coating surface.
The force is applied through the
centre of the Dolly by a hydraulically loaded pin.
This ensures an exactly central point-loading of the force.

UTM Machine

also known as auniversal tester,materials testing machineormaterials test frame, is used totestthetensile strength and compressive ,Peel , flexural strength of materials.
