Elasticity / Resistance Deformation Testers

Home » Products » Elasticity / Resistance Deformation Testers

Elasticity and resistance to deformation are part of the key physical properties required in the coatings industry today. Essentially there are three different test methods which are used to determine a coating’s performance under different deformation conditions.

Bend Test
A coated metal sheet is bent over a cylindrical or conical mandrel and the coating observed for cracks and discolouration.

Impact Test
A coated metal sheet is placed beneath a falling weight and the resultant damage caused by the deformation is observed. The impact test method is used to identify how the coating performs under a rapid deformation process

Cupping Test
A coated metal sheet is subjected to a gradual deformation by a polished die. This deformation is caused by the die being pushed from beneath the coating – ie from the reverse side of the sheet. The end point is when the coating begins to crack.

Elcometer 1620 Cupping Tester

by Graham Duk | posted in: Elasticity / Resistance Deformation Testers, Physical Test Equipment, Products | 0

This robust and user-friendly tester is used for assessing the cupping ability of coatings applied to metal sheets up to 1.2mm thick. The Elcometer 1620 Cupping Tester has a 27mm diameter hardened steel die in a clamping device and a 20mm diameter punch. A hand-rotated crank and reduction drive moves the punch progressively into the sample. The Elcometer 1620 Cupping Tester has a digital gauge with an illuminated magnifier to accurately view the resultant damage and provides accurate readings of … Read More

Elcometer 1506 Cylindrical Mandrel Bend Tester

by Graham Duk | posted in: Elasticity / Resistance Deformation Testers, Products | 0

The Elcometer 1506 Cylindrical Mandrel is a robust bend tester used to determine the elasticity, adhesion and elongation properties of cured coatings on sheet metal. The frame has a bending lever with height-adjustable rollers and a sliding vice for clamping the sample which means the test pieces are bent perfectly and regularly on decreasing mandrels until the desired effect can be observed. The instrument can be adjusted to the diameter of the mandrel used and the mandrels are easily changed. … Read More

Elcometer 1500 Set of Cylindrical Mandrels on a stand

by Graham Duk | posted in: Elasticity / Resistance Deformation Testers, Physical Test Equipment, Products | 0

The Elcometer 1500 Cylindrical Mandrel is a simple instrument for determining the elasticity, adhesion and cracking of dry paint on flat specimens, consisting of a mandrel support which also serves as a test stand. Coated metal sheets, maximum 150mm in length x 100mm wide, are manually and successively bent around mandrels of decreasing diameter until cracks appear. The Elcometer 1500 Set of Cylindrical Mandrels on a stand can be used in accordance with: AS/NZS 1580.402.1 ASTM D 2485 ASTM D … Read More

Elcometer 1510 Conical Mandrel Bend Tester

by Graham Duk | posted in: Elasticity / Resistance Deformation Testers, Physical Test Equipment, Products | 0

The Elcometer 1510 Conical Mandrel Bend Tester is used to determine the effects of bending on the elasticity, adhesion and elongation properties of cured coatings on sheet metal. The frame has a bending lever with a roller which pivots on a steel conical mandrel with a diameter from 3.2 – 38.1mm. A graduation indicates the mandrel diameter in both mm and inches. The specimen can be bent on part of, or along, the entire length of the mandrel, and the … Read More
