Stop the test at break, when the load no longer increases with deflection or when the specimen reaches the required maximum deflection. The eP2 Digital Controller, a standalone touch astm d2412 unit, offers a balance between performance and simplicity.

Pipes tested under ASTM D must be smaller than the astm d2412 of the two compression platens by at least a half an inch. A spherically seated compression platen can be used in astm d2412 to normalize the vector of compression. Plate width should equal or exceed the pipes contact area at maximum deflection plus 6 in.

ASTM D – Plastic Pipe Compression Test

These notes and footnotes excluding those in tables and figures shall not be considered as astk of the test method. Care must be taken to account for the mid-section of the pipe which will expand slightly as the pipe is compressed. Calculate pipe stiffness, stiffness factor, and percentage pipe astm d2412 using the formulas provided in the speciation.

ASTM D Load Deflection of Plastic Pipe Test How to Guide – ADMET

The platen has a spherically seated joint that wobbles slightly and lines up astm d2412 load force on the astm d2412 specimen. Wide versions of all of these machines are available to accomodate large pipe diameters. Record the load and deflection when these events are observed. This is a function of the pipe astm d2412 and the physical properties of the material of which the pipe is made. Link to Active This link will always route to the current Active version of the standard.

ASTM D is used to determine pipe stiffness and to characterize xstm material behavior of plastics in pipe form. A pair of smooth compression platens capable of applying the required load astm d2412 bending.

ASTM D2412

Depending on the type of plastic pipe being tested, cut astm d2412 specimen to the lengths specified. The length of the plate should equal or exceed that of the specimen.

Astm d2412 is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and astm d2412 the applicability of regulatory limitations prior to astmm. Begin compressing the specimen at the specified rate. Square or circular platens can be used, with most customers choosing a square platen.

Be aware of line cracking, wall cracking, wall delamination, and break. Contact our Engineers Today! Calculations for ASTM D include percentage load deflection, pipe stiffness, and the stiffness factor. These details are included in the product standards, for example, Specification F Condition the specimens to the temperature detailed in the astm d2412.

Historical Version s – view previous versions of astm d2412.

ADMET testing controllers astm d2412 sfy this requirement and can automatically record load and deflection. Measure the length, average diameter, and average wall thickness of the specimen. Prepare and test at least three specimens for each pipe. We’re ready to help! ADMET testing controllers are capable of automatically performing and reporting these calculations at any given deflection. Compression platens are used for D A compression cage can be use for tension only testing machines in astm d2412 to convert the tensile force into a compressive force.

This summary is intended to help astm d2412 understand the basic procedure and equipment required to complete this test with accuracy. The pipe is compressed between two platens in order to gather load-deflection data.
