ASTM D522 BS3900 E11 ISO6860 Tapered Shaft Bend Testing Machine Conical Shaft Bending Tester
Instroduction
The conical shaft bending tester. The changing conical diameter of the instrument enables the dry coating film of the metal sheet material to be stretched under different diameters. The length of the conical shaft is 200mm, the major end diameter is 37mm, and the minor end diameter is 3mm. When testing the sample, the coated metal sheet material sample is placed under the conical shaft for bending, and the ductility and adhesion of the paint film under the bending stress are qualitatively determined.
Compliant with standards
(1) Test methods for BS3900 E11 coating. Part E: Mechanical tests on coating films. Part 11: Bending test (cone mandrel)
(2) ISO6860 Paints and varnishes. Bending test (cone mandrel)
(3) ASTM D522 Standard test method for bending test of coated core rods
Technical Features
(1) The design is reasonable and the operation is simple. It can be directly placed on the workbench for use.
(2) It is wear-resistant and highly corrosion-resistant, meeting the requirements for repeated use.
(3) The design features three clamps, securely fixing the test samples.
(4) It is small in size, lightweight, convenient to carry, with stable performance and accurate results.
Main application
The conical shaft bending tester is suitable for measuring the flexibility and adhesion performance of coatings (especially metal coatings) when subjected to bending stress.
Operation method
(1) Place the test plate at the appropriate position and clamp it;
(2) By the rotational action of the rolls, cause the test plate to bend around the conical shaft;
(3) Bend the sample by 180 degrees within a certain rotational time and with uniform force;
(4) Remove the plate and check the cracking condition of the paint film;
(5) Record the location of the cracking, measure the distance from the conical end to the smallest segment of the cracking to the bending axis.
