This specification covers requirements and test methods for materials, dimensions, workmanship, ring stiffness, flattening, joint systems, and a form of marking for polyethylene (PE) pipe of profile wall construction and with bell and spigot, heat fusion, extrusion welded or electrofusion joints for use in gravity flow applications, such as for sewers and drains. The PE profile wall pipe products cover six standard ring stiffness constant (RSC) classifications, namely 40, 63, 100, and 160, 250 and 400. These are referred to as RSC 40, RSC 63, RSC 100, RSC 160, RSC 250 and RSC 400. Referee testing, ring stiffness constant testing, flattening test, and joint tightness test shall be performed to meet the requirements prescribed.This specification establishes nationally recognized performance requirements common to both kerosine and diesel portable containers for reuse by the consumer. Only color and marking are differentiated. The test medium specified for chemical resistance is kerosine due to the more aggressive nature of kerosine on elastomers and other materials of construction. Cautionary standards for handling and disposal of hazardous materials should be observed. Containers containing kerosene should not be opened in the presence of open flame or other sources of ignition. The stability test, handle strength test, drop strength test, hydrostatic pressure test, aging test, permeability test, immersion test, stress cracking test, corrosion resistance test, heat resistance test shall be performed on the container to meet the requirements prescribed.
