Plastics piping systems - Glass-reinforced thermosetting plastics (GRP) pipes and fittings - Methods for regression analysis and their use

This document specifies procedures suitable for the analysis of data which, when converted into logarithms of the values, have either a normal or a skewed distribution. It is intended for use with test methods and referring standards for glass-reinforced thermosetting plastics (GRP) pipes or fittings for the analysis of properties as a function of time. However, it can also be used for the analysis of other data. Two methods are specified, which are used depending on the nature of the data. Extrapolation using these techniques typically extends a trend from data gathered over a period of approximately 10 000 h to a prediction of the property at 50 years, which is the typical maximum extrapolation time. This document only addresses the analysis of data. The test procedures for collecting the data, the number of samples required and the time period over which data are collected are covered by the referring standards and/or test methods. Clause 6 discusses how the data analysis methods are applied to product testing and design.

Plastics piping systems for non-pressure underground conveyance and storage of non-potable water - Arch-shaped, corrugated wall chambers made of PE or PP used for retention, detention, storage and transportation of storm water systems - Product specifications and performance criteria

This document gives the definitions and specifies the minimum requirements for injection moulded and thermoformed thermoplastics corrugated arch-shaped chambers, including integral components, used in underground systems for retention, detention, transportation and storage of non-potable water (e.g. storm water) and manufactured from polyethylene (PE) or polypropylene (PP). These chambers are intended for buried underground use in one horizontal layer, e.g. in landscape, pedestrian or vehicular traffic areas. In the case of retention and detention systems, the main purpose of the chambers is to retain water, for later infiltration in the ground or for later use in non-potable applications (irrigation, cleaning, sanitary facilities, etc.) or to detain water during a storm, transferring it in a controlled way to the public storm water network. Applications include commercial, residential, agricultural and highway drainage, including installation under parking lots and roadways. Product performance is determined by a combination of material specification, product design and manufacturing process. These chambers are intended to be used as elements in a modular system where the manufacturer has provided a clearly documented method specifying how the components are assembled to create a complete retention, detention, storage or transportation system.
