This document specifies the characteristics and the requirements of unrestricted air gap Family A, Type A for nominal flow velocity not exceeding 3 m/s. Air gaps are devices for protection of potable water in water installations from pollution by backflow. This document applies to air gaps in factory-assembled products and to constructed air gaps in situ and specifies requirements and methods to verify and ensure compliance with this document during normal working use. The fluid in the receiving vessel is assumed to have similar properties to the water supply. Where this is not the case, additional care or tests could be required to verify the efficacy of the solution in practical use. The AA device is intended to be used in potable water installations according to EN 806 (series). Sanitary tapware when installed onto a receiving vessel (e.g. washbasin etc.) might have some restriction of its overflow. This will not compromise the water supply as the tapware might have an air gap, as detailed for example in EN 200 (dimension E), that provides an air gap disconnection. If this is the case, then backflow protection will be assumed to be adequate, and no further testing/verification will be needed.

This document specifies a classification of the main types of automatic steam traps according to the mode of actuation of their obturation device and disregarding their details of conception and construction.

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.
