Plastics piping systems for non-pressure underground drains and sewers - Unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) - Part 1: Specifications for ancillary fittings and shallow chambers

This document is part of a System Standard for plastics piping systems of a particular material for a specified application. There are a number of such System Standards. System Standards are based on the results of the work being undertaken in ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids”, which is a Technical Committee of the International Organization for Standardization (ISO). They are supported by separate standards on test methods, to which references are made throughout the System Standard. The System Standards are consistent with general standards on functional requirements and on recommended practice for installation. This document specifies the definitions and requirements for unplasticized polyvinyl chloride (PVC-U), polypropylene (PP) and polyethylene (PE) ancillary fittings and shallow chambers intended for use in non-pressure underground drains and sewers for wastewater. This document is applicable to: a) ancillary fittings and shallow chambers, intended for use buried underground outside the building structure; reflected in the marking of products by "U"; b) ancillary fittings and shallow chambers, intended for use buried underground both outside (application area code “U”) and within the building structure, reflected in the marking of products by "UD". This document also covers the jointing of the ancillary fittings and shallow chambers to the piping system. The document is applicable to the following ancillary fittings: - sealed access fittings; - rodding point covers; - rodding tees; - mechanical saddles. Ancillary fittings according to this document are intended for use in pedestrian areas, except rodding tees and mechanical saddles which can also be used in vehicular trafficked areas. Ancillary fittings can be installed to a maximum depth of 6,0 m from ground level, with the exception of rodding point covers with a maximum depth of 2,0 m. Shallow chambers according to this document are intended for use in private drains located in pedestrian areas above the ground water table, to a maximum depth of 2,0 m from ground level to the invert of the main flow channel. This document covers shallow chambers having a base with a flow channel and their joints to the piping system. Ancillary fittings and shallow chambers can be manufactured by various methods e.g. injection moulding, rotational moulding, spiral winding or fabricated. NOTE 1 Products complying with this document can be used with pipes, fittings and other components conforming to any of the plastics products standards listed in Annex E, providing their dimensions are compatible. NOTE 2 Products complying with this document can be installed in underground applications without additional static calculation. prEN 13598-1:2025 (E) 6 NOTE 3 Ancillary fittings and shallow chambers can be subject to national regulations and / or local provisions.

This document specifies business requirements for processes intended to preserve digital data. NOTE Data are stored and maintained for the purpose of retrievability and usability during the required archiving period. In addition, for the purpose of some business requirements, data are authentically preserved and accessed. This document is intended to allow for different implementations based on a company’s specific business environment. This document is not intended to incorporate company specific requirements and does not dictate specific organizational structures within a company. This document does not specify a design or an implementation of an archive system. Actual implementations can distribute responsibilities or break out functionality differently. This document assumes that all requirements for configuration management of the product data are in place and therefore are not specifically described in this document.

Testing of hardened concrete - Part 12: Determination of the carbonation resistance of concrete - Accelerated carbonation method

This document describes a method for evaluating the carbonation resistance of concrete using test conditions that accelerate carbonation. After a defined period of curing and a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide. NOTE The test performed under reference conditions takes a minimum of 112 days comprising a minimum age of the specimen prior to curing under water of 28 days, a minimum preconditioning period of 14 days and an exposure period to increased carbon dioxide level of 70 days. This procedure is not a method for the determination of carbonation depths in existing concrete structures.

Earthworks - Geotechnical laboratory tests - Part 5: Test method for measurement of one-dimensional swelling of soils under oedometric condition

This document describes the reference methods for the determination of swelling, swelling pressure, magnitude or potential of one-dimensional swelling of a soil when subjected, in the presence of water, to vertical stresses under oedometric conditions. It is used to assess the behaviour of earthwork platform that may be affected by the presence of swelling soils. These methods are used to determine three parameters related with the swelling of a soil: the swelling pressure, the swelling index and the constrained swelling pressure. These test methods specify the technique for specimen preparation, apparatus and procedure for quantifying the amount of height change associated with swelling and procedures for reporting test results. The procedures given in these test methods are applicable to undisturbed, remoulded, recompacted or reconstituted specimens.
