This test method covers the determination of loaddeflection
characteristics of plastic pipe under parallel-plate loading.
This test method covers thermoplastic resin pipe, reinforced
thermosetting resin pipe (RTRP), and reinforced polymer mortar pipe
The characteristics determined by this test method are pipe
stiffness, stiffness factor, and load at specific deflections.
The values stated in inch-pound units are to be regarded as
standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and
are not considered standard.
NOTE 1—While this test method can be used in measuring the pipe
stiffness of corrugated plastic pipe or tubing, special conditions
and procedures are used. These details are included in the product
standards, for example, Specification F405.
The text of this test method references notes and footnotes that
provide explanatory material. These notes and footnotes (excluding
those in tables and figures) shall not be considered as
requirements of the test method.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. 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.
