2、 in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers requirements and test methodsfor materials, dimension
3、s, workmanship, impact resistance,pipe stiffness, flattening, buckling, tensile strength of seam,joint systems, perforations, and markings for steel reinforcedthermoplastic pipe and fittings of nominal sizes 8 in. 200 mmthrough 120 in. 3000 mm. The steel reinforced, spirallyformed thermoplastic pipe
4、s governed by this standard areintended for use in underground applications where soil pro-vides support for their flexible walls. These pipes will be usedfor gravity flow and non-pressure applications, such as stormsewers, sanitary sewers, industrial waste applications anddrainage pipes.1.2 UnitsTh
5、e values stated in either inch-pound units orSI units are to be regarded separately as standard. Within thetext the SI units are shown in brackets. The values stated ineach system may not be exact equivalents: therefore, eachsystem shall be used independently of the other. Combiningvalues from the t
6、wo systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bil
7、ity of regulatory limitations prior to use.1.4 There is no similar or equivalent ISO standard.2.

20、 and Use4.1 Steel reinforced thermoplastic pipes are used for under-ground applications where soil provides support to theirflexible walls. Their main use is for gravity flow and non-pressure drainage of surface water, sanitary sewage and indus-trial waste.NOTE 1Industrial waste disposal lines shoul
