We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. By means of our plastic testing expertise and modular product design, we will help find the testing atsm that is right for you.

This test method also is applicable to extruded and molded thermoplastic pipe. These effects are discussed in References 3 and 4.

Reinforced thermosetting resin pipe may be tested by this standard regardless of fabrication method. Rather than testing a complete ring, two 4″ long segments of the ring are tested together in a special fixture fully defined in ASTM D 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.

The version of ASTM D has added a Procedure D, for testing polyethylene pipe with a nominal diameter of 14″ and greater and preferably having a wall astmm 1″ and greater. This potential error is analyzed and discussed in detail in References 2 and 3.

Details of the now obsolete fixture and specimen for testing filament-wound rings can be found can be found in and earlier versions of ASTM D Historical Version s – view previous versions of standard.


The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

The test cannot be considered significant for applications xstm widely from the load-time scale of the standard test.


Procedure D is used for polyethylene pipe with a nominal diameter of 14 in. Data from this test are useful for research and development, quality control specification and design. Wyoming Test Fixtures Inc. However, this now deleted original Procedure A fixture, while no longer an ASTM standard, is still used for testing filament-wound composite rings, and the fixture is available from Wyoming Test Fixtures, Inc.

ASTM D Plastic Pipe Hoop Tensile Strength Testing – ADMET

These former Procedure A specimens are hoop-wound rings of controlled diameter, width, and thickness, viz. One criticism is that some bending is induced in the ring specimen at the split. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

This test method is applicable to reinforced-thermosetting resin pipe regardless of fabrication method. These various specimen configurations and test procedures are fully defined in the version of ASTM D Reference 1. Extruded and molded thermoplastic piping is also covered by this test. In general, this test method is still generally considered an acceptable test for unidirectional hoop-wound composite rings.

Work Item s – proposed revisions of this standard. Procedure E is used for polyvinyl chloride PVC pipe with a nominal diameter of 14 in.

Procedure C has been used astk polyethylene and polybutylene pipe to produce results equivalent to Quick Burst results Test Method D for 4 in. Although this original Procedure A test method was an ASTM standard from toits popularity has varied over the years. The original Procedure B and C specimens, extruded and molded unreinforced plastic specimens and larger diameter extruded plastic pipe, respectively, utilized fixtures of the general type shown at the right side of Fig.


Friction between the split disk fixture and the ring specimen is also a concern. Have a question about conducting the test for this standard? All of these revised procedures use the same general fixture configuration the configuration shown on the right side of Fig. Procedure A is now used for testing reinforced-thermosetting resin pipe, Procedure B for thermoplastic pipe of any size, and Procedure C for thermoplastic pipe with nominal diameters of 4.

Within limits, specimens of varying sizes can be tested using the same holders, by using interchangeable pairs of split disks. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D Link to Active This link will always route to the current Active version of the standard.

The original fixture for testing Procedure A specimens, i. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.

The ASTM D standard determines aetm comparative apparent tensile strength of most plastic products using a split disk test fixture tested under defined conditions and test machine speed. Sources of Additional Information: We are confident that we have what you are looking for.
