This document specifies requirements and test methods for straight lengths of factory made thermally insulated bonded single pipe assemblies for hot water networks in accordance with EN 13941-1, comprising a steel service pipe, polyurethane foam thermal insulation and a casing of polyethylene.The pipe assembly can also include the following additional elements: measuring wires, spacers and diffusion barriers.

This document specifies the values or options chosen for the test parameters, i.e. the impact energy for unnotched specimens, specimen dimensions, shape and span of the specimen supports, and type of specimen for both unnotched and notched specimens, for testing the impact resistance (pendulum method) of thermoplastics pipes of the following materials, when the test method shall conform to ISO 9854-1. It applies to pipes made of unplasticized poly(vinyl chloride) (PVC-U), high-impact poly(vinyl chloride) (PVC-HI), oriented unplasticized poly(vinyl chloride) (PVC-O), chlorinated poly(vinyl chloride)(PVC-C), acrylonitrile/butadiene/styrene (ABS), acrylonitrile /styrene/acrylate (ASA), propylene homopolymer (PP-H), propylene impact polymer (PP-B), propylene random copolymer (PP-R), propylene random copolymer with modified crystallinity (PP-RCT), and polyethylene(PE).

This document specifies the general test method to be used for the determination of the impact properties of unnotched and notched specimens cut from thermoplastics pipes for the transport of fluids. It is not intended to be a reference test method for the determination of the impact strength of pipes. This document may be applied to either isolated batches or continuous production of pipe and the test can be carried out at – 20 °C, 0 °C or 23 °C, depending on the pipe material and/or size. For the test parameters, i.e. impact energy, specimen dimensions, type and span of the specimen supports and type of specimen, to be used to determine the pendulum impact strength of pipes, the specifications for specific materials are given in ISO/DIS 9854-2, as appropriate.

This document specifies classification, general requirements and test methods for flexible, factory made, buried district heating pipe systems.This document is intended to be used in conjunction with part 2 or 3, as applicable.This document is applicable to a maximum continuous media temperature of 80 °C (part 2 and 3) and design pressures of 0,6 MPa to 1 MPa.The pipe systems are designed for a service life of at least 50 years. For pipe systems with plastic service pipes, the respective temperature profiles are defined in EN XXXX-2 and EN XXXX-3.NOTE For the transport of other liquids, for example potable water, additional requirements can be applicable.

This document specifies requirements and test methods for flexible, factory made, buried district heating pipes systems with plastic service pipes and no bonding between the layers of the pipe assemblies.It is only applicable in conjunction with part 1.This document is applicable to a maximum continuous media temperature of 80 °C and maximum operating design pressures up to 1,0 MPa for a design service life of at least 50 years.This document does not apply to cover surveillance systems.In conjunction with the other parts of EN XXXXX, this document is applicable to pipes, fittings, their joints and to joints with components made of non-plastics materials intended to be used for district heating installations.

This document specifies the requirements for cork floor coverings made from agglomerated composition cork, with or without a decorative surface layer, with or without applied colours, supplied in tile form which are designed to be used with a factory finish and/or an in situ finish.The cork floor decorative surface layer can be made of cork or other bio-based decorative materials, e.g. wood or bamboo veneers, linoleum, leather or natural fibres.This document includes a classification system based on intensity of use which shows where cork floor tiles with a factory finish can give satisfactory service (see EN ISO 10874). It also specifies requirements for marking, labelling and packing.

This document specifies methods for determining the ring creep properties for glass-reinforced thermosetting plastics (GRP) pipes. Properties include the creep factor and the long-term creep stiffness. Testing is performed under either wet (total immersion in water) or dry conditions. Dry creep testing is typically performed for the assessment and control of raw material consistency. Wet creep testing is typically undertaken to determine the long-term creep performance in simulated use conditions.

This document specifies test methods for flexible non-thrust resistant socket-and-spigot joints with elastomeric sealing elements for buried and above ground glass-reinforced thermosetting plastics (GRP) pipeline applications. It covers methods of test for the leaktightness and resistance to damage of the joint only, when subject to specified combinations of longitudinal extension (draw), angular movement (angular deflection), compression (deformation) perpendicular to the pipe axis and internal pressure. This document is applicable to joints for either pressure or non-pressure applications. These test procedures are applicable to joints for pipes and fittings of all nominal sizes. The tests are suitable for the evaluation of joints intended for applications in which the liquids are conveyed at temperatures specified in the referring standards. The test procedures in this document are damaging to the test piece which will not be suitable for reuse after these tests. The test procedure shall be applied for type testing purposes.
