Measurement of coating thickness on the applied substrate

Standards

• ASTM D 6132, ISO 2808 - Ultrasonic Technique.Measuring range - 0.5 to 150 mils
• ASTM E 376 - Magnetic adhesion property through eddy currents

Significance:

• Ferrous models will measure all non-ferromagnetic coatings on steel and iron.
• Non-Ferrous models will measure all non-conductive, non-Non-Ferrous substrates.

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

Standards

• ASTM 2794,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.

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

Standards

• ASTM,BS.
• 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.

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

Standards

• ASTM D 552
• BS 3900-E11
• SO 6860

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.

Defined as resistance to indentation or scratching

Standards

• ASTM D5178,
• D2197
• BS 3900
• ISO 1518

• The scratching needle is a harderned 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.

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.
