The flexibility test is designed to check the resistance of three-layer polyolefin coatings applied on metal to bending at different angles. This test is performed on cut pipe samples. This device is designed in accordance with ISO 21809-1 (2014) and ISO 21809-2 (2014) standards, and it has the possibility of examining samples at different bending angles.
Device components:
The flexibility testing machine has a hydraulic system to apply force, a base and mandrel system to apply bending, and a digital protractor to observe the degree of bending of the sample.
Test sample:
Coated laboratory samples should be cut to dimensions of at least 200 mm in length and about 25 mm in width along the axis of the pipe, or a coated laboratory sample with dimensions of 6.4 x 25 mm and a length of at least 200 mm should be used.
