Describes a method of determining the sieve residue of polymer dispersions. Refers only to coagulum-type content, i.e. of particles much greater in diameter than the mean diameter of the other particles.

This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the renovation of underground non-pressure drainage and sewerage networks. It is applicable to pipes, fittings and assemblies, made from thermoplastic composite materials, as manufactured and as installed. It is not applicable to the existing pipeline. It is applicable to technique families for renovation: — lining with spirally-wound (SWO) pipes; — lining with a rigidly anchored plastic inner layer (RAPL). and intended to be used at an operating temperature of 20 °C as the reference temperature. In the case of lining with SWO pipes, where the pipes, are formed on site, to a fixed or variable diameter, by spirally winding and jointing a pre-manufactured profiled plastics strip, this document applies to, strips made of unplasticized poly(vinyl chloride) (PVC U), or of polyethylene (PE), with or without steel stiffening elements, and installed with or without integral locking mechanism. In the case of lining with RAPL, where a single rigid annulus of structural cementitious grout is formed behind a plastics inner layer serving as permanent formwork anchored to the grout. This document applies to integrally joined profiled plastics strips of PVC-U or PE or studded sheets of PE, and grout systems with or without steel reinforcement. It does not apply to the structural design of the lining system. NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this document.

This document specifies a test method for determining the long-term compression strength for a specified period on boxes made of thermoplastics materials for non-pressure underground conveyance and storage of non-potable water. The document is applicable for boxes which maintain their linear behaviour over the specified period.

This document specifies a test method for determining the compressive creep behaviour of boxes made of thermoplastic materials intended for use in a modular system for non-pressure underground conveyance and storage of surface water.

This document gives the definitions and specifies the minimum requirements for injection moulded, extruded and thermoformed thermoplastics cuboid shaped boxes, including integral components, used in underground systems for infiltration, attenuation and storage of surface water (e.g. storm water) and manufactured from polypropylene (PP) or unplasticized polyvinylchloride (PVC-U). Product properties are determined by a combination of material specifications, design and manufacturing process. These boxes are intended for buried underground use, e.g. in landscape, pedestrian or vehicular traffic areas. A box can either be factory assembled, or site assembled from different components. These boxes are intended to be used as elements in a modular system where the manufacturer states in the documentation how the components are assembled to create a complete infiltration, attenuation or storage system. NOTE Non load bearing component(s) can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, thermoforming and low-pressure injection moulding.
