ASTM D – Plastic Pipe Compression Test

The pipe is compressed between two platens in order to gather load-deflection data. Compression platens are used for D While this test method can be used in measuring the pipe stiffness of corrugated plastic pipe or tubing, special conditions and procedures are used.

ASTM D is used d242 determine pipe stiffness and to characterize the material behavior of plastics in pipe form. These details are included in the product standards, for example, Specification F A compression cage can be use for tension only testing machines in order to convert the tensile force into a compressive force.

This is a function of the pipe dimensions and the physical properties of the material of which the pipe is made. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Pipes tested under ASTM D must be smaller than the envelope of the two compression platens by at least a half an inch. A spherically seated compression platen can be used in order to normalize the vector of compression.

These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the test method. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Care must be taken to account for the mid-section of the pipe which will expand slightly as the pipe is compressed. The platen has a spherically seated joint that astj slightly and lines up the load force on the pipe specimen. Square or circular platens can be used, with most customers choosing a square platen.

Calculations for ASTM D include percentage load deflection, pipe stiffness, and the stiffness factor. Historical Version s – view previous versions of standard.
