Standard Test Methods for Physical Properties of Smooth-Wall, Coilable, Polyethylene (PE) Conduit (Duct) for Preassembled Wire and Cable (Withdrawn 2016)
SIGNIFICANCE AND USE
Environmental performance test values for smooth-wall, coilable, medium density and high density polyethylene (MDPE and HDPE) conduit (duct) for preassembled wire and cable may provide data for research and development, engineering design, quality control, and acceptance or rejection under specifications.
SCOPE
1.1 These test methods cover procedures for determining the environmental performance properties of smooth-wall, coilable, medium-density and high-density polyethylene (MDPE and HDPE) conduit (duct) for preassembled wire and cable.
1.2 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only.
1.3 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.
WITHDRAWN RATIONALE
These test methods cover procedures for determining the environmental performance properties of smooth-wall, coilable, medium-density and high-density polyethylene (MDPE and HDPE) conduit (duct) for preassembled wire and cable.
Formerly under the jurisdiction of Committee F17 on Plastic Piping Systems, these test methods were withdrawn in November 2016. This standard is being withdrawn without replacement due to its limited use by industry.
