Flexible Packaging Testing Equipments. Composite Films Testing Instruments. Wood d2974-93 Laminates Testing Instruments. If no cracks are evident, repeat the procedure at a greater height, increasing 1 in. Be sure the panel is? Ceramics and Glass Testing Equipments. We also built a six-foot tall tester for custom testing. The indentation can be either an intrusion or an extrusion. 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.

In its use over many years, this test wstm 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. Plastic Barrel Testing Equipments.

An impact test which is useful for testing paint and coating adhesion is ASTM D, the drop test performed on a universal impact tester see top photo. Raise the weight up the tube to a height where it is expected that no failure will occur.


A superscript epsilon e indicates an editorial change since the x2794-93 revision or reapproval.

Moisten the probe sponge with tap water and slowly draw the probe over the impact area. Heat Sealing Testing Instruments. Food and Beverages Testing Equipments.

Marble Floor Tiles Testing Instruments. Interlaboratory agreement is improved when ranking is used in place of numerical values.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

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. 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.

Film and Foil Testing Instruments. The head rests on the test panel and the punch is held vertically by a guide ring. Interlaboratory agreement is improved when ranking is used in place of numerical values. Density and Specific Gravity Testing Instruments.
