The test method defined in the ASTM D2412 standard developed by the American Society for Testing and Materials (ASTM) covers the determination of the load-deflection properties of plastic pipe under parallel plate loading. This test method covers thermoplastic resin pipe, reinforced thermoset resin pipe and reinforced polymer mortar pipe.
In this standard, whose full name is "ASTM D2412-21 Standard test method for determining the external loading properties of plastic pipes with parallel plate loading", the properties determined by the test method are pipe stiffness, hardness factor and load in certain deviations.
Special conditions and procedures apply when this test method is used to measure the pipe hardness of corrugated plastic pipe or pipes, other profile wall designs, and products made from polyethylene, PVC or polypropylene. These details are included in the product standards.
The ASTM D2412-21 standard is used to determine pipe stiffness and characterize the material behavior of tubular plastics. There are many different materials used to make pipes, so it is important to define this test as only thermoplastic resin pipe, reinforced thermoset resin pipe, and reinforced polymer mortar pipe. Other pipe types, such as PVC, are not specifically covered under this test, but the ASTM D2412 standard is used as a backup procedure and is referenced in many similar ASTM tests for hollow pipes and tubing.
During testing, the pipe is clamped between two plates to collect load deviation data. Load measurements are taken at fixed intervals.
Pipe tested under ASTM D2412 should be at least half 13 mm smaller than the envelope of the two compression plates. Square or circular platens are available, with most customers choosing a square platen. Care is taken to consider the middle section of the pipe, which will expand slightly when the pipe is compressed. Compression plates are used in the tests. A compression cage can only be used for tensile testing machines to convert tensile force into a compression force.
