Abstract: This paper discusses current specifications, including materials for plastic pipe as compared to other pipe specifications, including rigid pipe materials. It discusses the ambiguities in these plastic pipe specifications as well as the inanitions in these specifications, which can lead the specification user astray, and allow conditions that may result in failure. More particularly, the issues discussed herein are not only the lack of information, but in fact the existence of disinformation in those specifications as they relate to deflection limitations, and any corrective action that may be or is taken to overcome overdeflections. Also discussed is the absence of limitations as to the materials used in these pipes, including the absence of any specification as to fillers, impurities and geometric requirements.
