Plastic and Composite Pipe - Physical and Mechanical Tests
Microbac Laboratories' Hauser Division performs hoop-tensile tests on both thermoplastic pipe and reinforced thermosetting pipe in accordance with ASTM D2290. Pipe sizes up to and including 33 inches in diameter can be tested with a total force of up to 60,000 lbf.
Hoop Tensile Stress Rupture
Hauser has unique facilities for conducting hoop-tensile stress-rupture tests on specimens of up to 33 inches in diameter and with sustained loads of up to 35,000 lbf.
Hauser determines pipe stiffness of virtually all sizes and types of pipe in accordance with ASTM D2412.
We perform room-temperature and low-temperature tup-type impact tests on most types and sizes of plastic and composite pipe in accordance with ASTM D2444.
Hauser runs a variety of chemical resistance procedures, including ASTM D3681 for fiberglass sewer pipe, ESCR tests, Green Book coupon tests, and simulated service tests.
Hauser has complete facilities for conducting standard plastics and resins tests, including those used for establishing cell class. Such tests include, in part, compression molding, specimen preparation, tensile, flex, izod impact, heat distortion, density, hardness, chemical resistance, flammability, and weathering.
Composition and Chemistry
We identify and quantify fillers, additives, unreacted components, and contaminants using a variety of analytical techniques. Reinforcement type, quantity, and orientation can be established using microscopy, pyrolysis, digestion, and dissection.
The Hauser Division is accredited to ISO 17025 by the American Association for Laboratory Accreditation (A2LA) in mechanical testing and chemistry, and by the Geosynthetic Accreditation Institute (GAI) for polyethylene materials (product specific). Hauser is a member of the Plastics Pipe Institute (PPI) and ASTM International.
