Universal Impact Testing – ASTM D2794
Compound Resin Testing Equipments. Moisten the probe sponge with tap water and slowly draw the probe over the impact area. Pipes Industry Testing Equipments. NOTE 3—The copper sulfate solution will not perform properly on zinc-phosphate-treated metal unless the conversion coating cracks.
Injection Molding Testing Equipments. Food and Beverages Testing Equipments. The indentation can be either an intrusion or an extrusion. Last previous edition approved in as D — 93 e1. 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. Composite Films Testing Instruments. Be sure the panel is? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Footwear Industry Testing Equipments.
Graduations are marked in inch-pounds along the slot. Conduct the test in the same environment or immediately on removal therefrom. Ceramics and Glass Testing Equipments. Test in a random fashion so that all impacts from one height are not made in succession or on one panel. Rigid Plastic Testing Equipments. Plastic Barrel Testing Equipments.
Composites Material Testing Equipments. Heat Sealing Testing Instruments. After the coatings have cured, a standard weight is dropped a distance to strike an indenter that deforms the coating and the substrate. Foam And Gaskets Testing Equipments. Filling Line Testing Equipments. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefax d279-93, or service astm. Tearing Resistance Testing Instruments.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Paper and Tissue Testing Instruments. Prepare a minimum of four coated panels for the material. Summary of Test Method 4. Non-metal Materials Testing Instruments.
Coatings attached to substrates are subjected to damaging impacts during the manufacture of articles and their use in service.
Components Material Testing Equipments. NOTE 4—Because of the poor reproducibility of this method, the reporting of inch-pounds kilogram-metres in comparing coatings for impact resistance should be restricted to one laboratory. Impact Resistance Tester For Paint: Thickness Measurement Testing Instruments.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Once visible cracks have d279493 identified, the test is repeated five times at that level, as well as five times above and below that level.
The head rests on the test panel and the punch is held vertically by a guide ring. As coatings such as atsm, varnish, conversion coatings, and related coating products are subjected to impact damage during their manufacturing and useful life, d279493 test method for impact resistance has been found to be useful in predicting coating resistance to impact.
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.
