3、rtment of Defense.1. Scope*1.1 This specification covers water well casing pipe andcouplings made from thermoplastic materials in standarddimension ratios (SDR), SCH 40 and SCH 80.1.2 Specifications are provided for the application of thesematerials to water well and ground water monitoring applica-
4、tions. Flush threaded joint systems are included for screen andcasing used primarily in the construction of ground watermonitoring wells (see Practice D5092).1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI uni
5、ts that are provided for information onlyand are not considered standard. (See IEEE/ASTM SI 10.)NOTE 1Certain field conditions may require alternative materials toensure safe long-term use. The user should consult federal, state, and localcodes governing the use of thermoplastic materials for well c
6、asing ormonitor pipe.NOTE 2This standard specifies dimensional, performance and testrequirements for plumbing and fluid handling applications, but does notaddress venting of combustion gases.1.4 Although the pipe sizes and SDR values listed in thisspecification are generally available, numerous othe
7、r plasticpipes in Schedule 40 and 80 wall, other SDR values andvarious outside diameters have been used for well casing. Suchproducts are often selected because they fulfill certain needsand Annex A1 includes a list of these Plastic Pipe Well CasingSpecials.1.5 The following safety hazards caveat pe
