ASTM D2444 Test

ASTM D2444, Standard Practice for Determining the Impact Strength of Thermoplastic Pipes and Fittings by Tube (Drop Weight) covers the determination of the impact resistance of thermoplastic pipe and fittings by means of a tube (falling weight) under certain impact conditions. Three interchangeable striker noses differing in geometric configuration are used on the tube. Two sample holders are defined.

ASTM D2444 Test

ASTM D2444 includes processes for determining the resistance of thermoplastic pipes and fittings to impact applied by impact tip (weight reduction) under certain conditions. The impact tip must have a mass of 6, 12, 20 or 30 lbs (2.7, 5.4, 9.1 or 13.6 kg) and be released from a minimum height of 2 ft (0.6 m) and a maximum of 10 ft (3.0 m). There are three interchangeable inserts for the impact tip. Type A has a round-tipped funnel, Type B has a cylinder with a relatively flat surface, and Type C has a 0.5'' diameter nail with a rounded tip. Two types of supports (either V-block or flat plate) are defined as standard. A combination of test variables should be used that allows the test to be easily administered with minimal or no harm to personnel, and yields reasonably reproducible results.

The impact resistance of thermoplastic pipes and fittings is related to the quality of the application and its suitability for operation. It can also provide a relative measure of the tested material's resistance to breakage during transportation and laying, and to breakage during use in non-buried applications. The results from this test can be used to lay the groundwork for establishing impact test requirements in product standards for measuring applications and changes in material on the product, and the effects of the environment on pipes and fittings.
