This document specifies materials and the general aspects of polyethylene (PE) piping systems in the field of the supply of gaseous fuels. NOTE For the purpose of this document, the term gaseous fuels includes, for example, natural gas, methane, butane, propane, hydrogen, manufactured gas, biogas, and mixtures of these gases. This document also specifies the test parameters for the test methods referred to in this document. In conjunction with ISO 4437-2, ISO 4437-3, ISO 4437-4 and ISO 4437-5, this document is applicable to PE pipes, fittings and valves, their joints, and joints with components of PE and other materials intended to be used under the following conditions: a) a maximum operating pressure (MOP) up to and including 10 bar11 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2., at a design reference temperature of 20 °C; b) an operating temperature between -20 °C and 40 °C. For operating temperatures between 20 °C and 40 °C, derating coefficients are specified in ISO 4437-5. The ISO 4437 series covers a range of MOPs and gives requirements concerning colours. It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes.

 

This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the rehabilitation of underground non-pressure and pressure drainage and sewerage networks, and of water supply networks which transport water intended for human consumption, including raw water intake pipelines. It is applicable to the renovation technique family: — lining with cured-in-place pipes (CIPP). It applies to the use of thermoset composite materials with various thermosetting resin systems, in combination with compatible fibrous carrier materials, reinforcement, and other process-related plastics components (see 5.1). It is applicable to pipes and fittings, as manufactured, as well as to the installed system, with service temperatures up to 50 °C for drainage and sewerage networks and up to 25°C for water supply networks. For pressurised networks, this document applies to independent (fully structural, class A) and interactive (semi structural, class B) pressure pipe liners, as defined in ISO 11295, which do not rely on adhesion to the existing pipeline. It does not include requirements or test methods for resistance to abrasion, cyclic loading or impact, which are outside the scope of this document.

 

This document gives guidance and requirements for the assessment of conformity of compounds, products, joints and assemblies in accordance with the applicable part of EN 12666, intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of certification procedures. NOTE 1 A test matrix provides an overview of the testing scheme in Annex A, Table A.1. NOTE 2 If certification is involved, the certification bodies and inspection bodies operating in accordance with EN ISO/IEC 17065 [1] and EN ISO/IEC 17020 [2] are considered to be competent. In conjunction with FprEN 12666-1 this document is applicable to Plastics piping systems for non-pressure underground drains and sewers - Polyethylene (PE). The application area code used in the marking of pipes and fittings indicates which application area(s) the products are intended: U: for the area more than 1 m from the building to which the buried piping system is connected, and UD: for application area U and the area under and within 1 m from the building where the pipes and the fittings are buried in ground and are connected to the soil and waste discharge system of the building.

 

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 methods for determining the change of appearance and stability of a textile floor coverings or any damage caused by detachment of layers, opening of joints, cracks, or crazing of a resilient, laminate or modular mechanical locked floor coverings under the movement of a swivel castor chair.
