ASTM D() Standard Testing Instruments
NOTE 3—The copper sulfate solution will not perform properly on zinc-phosphate-treated metal unless the conversion coating cracks. Graduations are marked in inch-pounds along the slot. Current edition approved June 1, The presence of cracks will be indicated by an audible alarm. Once visible cracks have been identified, the test is repeated five times at that level, as well as five times above and below that level.
Raise the weight up the tube to a height where it is expected that no failure will occur. Be sure the panel is?

Test in a random fashion so that all impacts from one height are not made in succession or on one panel. Food and Beverages Testing Equipments. Pipes Industry Testing Equipments.

The head rests on the test panel and the punch is held vertically by a guide ring. Water Vapor Permeability Testing Instruments. In its use over many years, this test method for impact resistance has been found to be useful in predicting the performance of organic coatings for their ability to resist cracking caused by impacts.
An impact test which is useful for testing paint and coating adhesion is ASTM D, the drop d2794-9 performed on a universal impact tester see top photo.
Select from list below: Thickness Measurement Testing Instruments. Composite Films Testing Instruments. Plastic Bottles Testing Instruments. Of course, these confirmation tests are conducted in a random order so successive tests are not conducted at the same height or on the same panel.
We also built a six-foot tall tester for custom testing. Other gage steel panels may be used if agreed upon between the producer and the user.
By gradually increasing the distance the weight drops, generally 1 inch 25 mm at a time, the point at which failure usually occurs can be determined.
