4、ction of polyethylene (PE) pipe for gravityflow applications.NOTE 1Non-pressure applications pertain principally to any munici-pal or private facilities for storm drainage, storm sewer, culvert andsanitary sewer applications. The products utilizing the criteria under thispractice are not intended fo

Significance and Use4.1 The utilization of recycled materials in non-pressurethermoplastic pipe presents a potentially large outlet for thiswhat is typically classified “was
20、te” material. The proper useand qualification of this material is critical in assuring itslong-term performance from both a structural and durabilitystandpoint.4.2 This practice defines minimum requirements and testingprotocols and frequencies for these recycled materials withrespect to their utiliz
21、ation in final thermoplastic pipe products.Each specific pipe standard has unique criteria that must be metin addition to the items described in this practice.4.3 The purpose of this specification is for characterizationof recycled plastics only and does not establish performanceguidelines for such
22、materials. Product specifications may beused in conjunction with this specification to establish perfor-mance specifications for a defined end-use and specific mate-rial type.5.
