This part of EN 1852 specifies definitions and requirements for solid wall pipes with smooth internal and external surfaces extruded from the same compound throughout the wall, fittings and the system of polypropylene (PP) piping systems in the field of non-pressure underground drains and sewers for wastewater. NOTE 1 Products complying with this document can also be used in non-pressure underground drains and sewers for surface water. This document is applicable to: — solid wall pipes and fittings which are intended to be used buried underground outside the building structure reflected in the marking of the products by "U", and — solid wall pipes and fittings which are intended to be used buried underground both outside (application area code “U”) and within the building structure reflected in the marking of products by "UD". This document specifies the test parameters for the test methods referred to in this document. NOTE 2 Multilayer pipes with different compounds throughout the wall are covered by EN 13476 2 [1] (see also CEN ISO/TR 27165 [2]). NOTE 3 Plastics piping systems made of PP with mineral modifiers (PP-MD) are covered by EN 14758-1 [3]. This document covers a range of nominal sizes, and pipe series and gives recommendations concerning colours. NOTE 4 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. This document is applicable to PP pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure underground drains and sewers. Fittings can be manufactured by injection-moulding or be fabricated from pipes, fittings and/or mouldings. NOTE 5 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex C can be connected to pipes and fittings conforming to this document, when they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 14.

This document specifies a test method to determine the suitability of a soil to be treated with lime and/or hydraulic binders, with regard to volumetric swelling and mechanical strength, within a period not exceeding two to three weeks.

This test can be integrated into the general method of a study of treatment of materials with lime and/or a hydraulic binder, in compliance with standard EN 16907-4.

It is applicable to soils and alternative (or anthropogenic) materials treated with lime and/or hydraulic binders for the construction of embankments and capping layers; in the areas of roads, railways and airports; industrial or commercial platforms; hydraulic works and road foundations.

The results of this test:

— are only valid for the configuration tested (soil, treatment product, dosage);

— are in no case usable for dimensioning a structure including treated materials.

The values currently accepted to define treatment suitability are indicated for information in Annex A.

This document describes a test method for the determination of the water content of samples of bituminous mixtures. The test method is suitable for checking conformity to a product specification, where required. Exposure levels are related to both handling procedures and ventilation provision and it is emphasized that adequate training should be given to staff employed in the usage of these substances.

This document specifies a framework of additional characteristics and associated test methods for bitumens and bituminous binders, which is complementary to other product standards for bitumens and bituminous binders. This document is applicable to bitumens and bituminous binders suitable for use in paving applications, but it is also applicable for other uses such as waterproofing membranes. With regard to paving applications, the following characteristics are addressed: - resistance to permanent deformation (rutting); - resistance to low-temperature cracking; - resistance to ravelling; - resistance to fatigue cracking; - temperature susceptibility; - equi-stiffness temperature and phase angle; - durability (evolution of equi-stiffness temperature and phase angle); - mixing and handling characteristics (paving and compaction) temperatures; - additional characteristics (e.g. solubility, elastic recovery and storage stability). Not all the properties and characteristics established in the framework are universally relevant to all binders. For example, elastic recovery is not relevant for unmodified binders.
