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 the standard. The values given in parentheses are provided for information only ). Note 1—Certain field conditions may require alternative materials to ensure safe long-term use. The user should consult federal, state, and local codes governing the use of thermoplastic materials for well casing or monitor pipe. Note 2—This standard specifies dimensional, performance and test requirements for plumbing and fluid handling applications, but does not address venting of combustion gases. 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 Annex A1 includes a list of these Plastic Pipe Well Casing Specials. 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. |
