DEEP DRAWING, ELASTICITY AND ADHESIVE QUALITIES OF PAINTS, LAQUERS & OTHER PROTECTIVE COATINGS APPLIEDTO A METAL SUBSTRATE. 

The standards call for a hemispherical indenter of 20mm diameter made from hardened polished steel.

The indenter is applied under pressure to the uncoated side of the test panel; concentric with the indenter is a corresponding die. As the test panel is deformed the coated surface is kept under observation for any change in surface coating: i.e. cracking, loss of adhesion.

Features:

  • ◆ New improved ergonomic design for ease of use and viewing of test.
  • ◆ 0ne handed crank operation.
  • ◆ Precision gearbox providing linear force transmission 2mm ball travel.
  • ◆ Magnetically retained 20mm Chrome Steel Ball.
  • ◆ Reproducible results guaranteed irrespective of material coating thickness.
  • ◆ LCD displaying indent depth to 0.01mm resolution.
  • ◆ Pivotal integrated x 2.5 illuminated magnifier.
  • ◆ Measuring system range 0 – 12 mm.
  • ◆ Accepts standard 150mm x 100mm (6” x 4”) steel test panels up to 1.25mm thick.
  • ◆ Capable of cupping 3mm thick aluminium test panels.
  • ◆ Auto switch off.
  • ◆ Battery powered.

OPERATING PRINCIPLE:

Specimen is clamped between two precision machined and ground dies under a definite clamping pressure of 1000 kg. This is obtained by turning 2 levers clockwise till the plate-springs are fully flattened out.

Main load is given by turning a handle simply as in a domestic manual type sewing machine which transmits the load through a 'worm and wheel' mechanism on to the ball penetrator with the maximum mechanical advantage.

The machine has been designed in an inclined position so that the operator while comfortably seated can draw the specimen by turning the lever and also can keep looking at the specimen through FRESNEL LENS to detect the first appearance of the hair-line crack when he has to stop the test.

The depth of penetration can be read from the digital gauge attached to the tester

CONFORMS TO  BS 3900 E4, BS EN ISO 1520, DIN 53166, DIN 53232, JIS K5600-5-2 and JIS B7729, NBN T22-104 , NF T 30 019.
