1. Scope | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1.1 This specification covers water well casing pipe and couplings made from thermoplastic materials in standard dimension ratios (SDR), SCH 40 and SCH 80. 1.2 Specifications are provided for the application of these materials to water well and ground water monitoring applications. Flush threaded joint systems are included for screen and casing used primarily in the construction of ground water monitoring wells (see Practice D5092). 1.3 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. (See IEEE/ASTM SI 10.) 1.4 Although the pipe sizes and SDR
values listed in this specification are generally available,
numerous other plastic pipes in Schedule 40 and 80 wall, other SDR
values and various outside diameters have been used for well
casing. Such products are often selected because they fulfill
certain needs and 1.5 The following safety
hazards caveat pertains only to the test method portion, Section 6,
of this specification: 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.
