Filling Line Testing Equipments.
Footwear Industry Testing Equipments. Coatings attached to substrates are subjected to damaging impacts during the manufacture of articles and their use in service.
The head rests on the test panel and the punch is held vertically by a guide ring. Tearing Resistance Testing Instruments. Opaque Glasses Testing Instruments. Rigid Plastic Testing Equipments. Summary of Test Method 4. Conduct the test in the same environment or immediately on removal therefrom. After the coatings have cured, a standard weight is dropped a distance to strike an indenter that deforms the coating and the substrate.
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. Universal Impact Testing — ASTM D Touchstone offers various aatm of impact testing including Charpy and Izod impact testing and micro-scale impact tests performed inside a scanning electron microscope.

Air Permeability Testing Instruments. We also built a six-foot tall tester for custom testing. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Place the test panel in the apparatus with the coated side either up or down as speci? Once visible cracks are observed, repeat the test? This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Current edition approved June 1, Touchstone offers various kinds of impact testing including Charpy and Izod impact testing and micro-scale impact tests performed inside a scanning electron microscope. Test in qstm random fashion so that all impacts from one height are not made in succession or on one panel. The organic coatings under test are applied to four or more suitable thin metal panels.
Flexible Packaging Testing Equipments. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Your comments atm receive careful consideration at a meeting of the responsible technical committee, which you may attend.

The value where the results change from mainly passing to mainly failing is the impact failure end point.
ASTM D2794 – 93(2010)
Impact Atm Testing Instruments. A number in parentheses indicates the year of last reapproval. For tests on coatings for crack formation; breaking off; adhesion and elasticity. Compound Resin Testing Equipments. Link to Active This link will always route to the current Active version of the standard. Water Vapor Permeability Testing Instruments.
NOTE 1—The coatings should be applied in accordance with Practices Dor as 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. Precision and Bias ASTM D provides a procedure for rapidly deforming by impact a coating film and its substrate and for evaluating the effect of such a deformation.
