Plastics rainwater piping systems for above ground external use - Unplasticized poly(vinyl chloride) (PVC-U) - Part 1: Specifications for pipes, fittings and the system
This standard specifies the requirements for pipes, fittings, brackets and the system of unplasticized poly(vinyl chloride) (PVC-U) intended for use as above-ground external rainwater downpipes.
It also specifies the requirements for metallic brackets.
It specifies both solid wall pipes and fittings, (i.e. product manufactured from a single layer), as well as solid wall multi-layer pipes.
Pipes can be used in conjunction with fittings and brackets of acrylic materials provided these polymers meet the performance requirements of this standard.
It also specifies the test parameters for the test methods referred to in this standard.
These products are usually used in conjunction with gutters conforming to EN 607[1]. They are not intended for use with products conforming to EN 612[2].
It is applicable to PVC-U rainwater systems of circular, square, rectangular or any other shape with sealed (rubber ring or solvent cement) or unsealed joints.

European foreword This document (EN 12200-1:2016) has been prepared by Technical Committee CEN/TC 155 “Plastics piping systems and ducting systems”, the secretariat of which is held by NEN. This document supersedes EN 12200-1:2000. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2016, and conflicting national standards shall be withdrawn at the latest by October 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This European Standard has been prepared in liaison with CEN/TC 128 “Roof covering products for discontinuous laying and products for wall cladding” taking into account EN 607 [1] and EN 1462 and CEN/TC 165 “Waste water engineering” taking into account the design guidance in EN 12056-3 [4]. This standard is a 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 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. EN 12200 consists of the following Parts, under the general title “Plastics rainwater piping systems for above ground external use — Unplasticized poly(vinyl chloride) (PVC-U)”: — Part 1: Requirements for pipes fittings and the system (the present standard); — Part 2: Guide for the assessment of conformity [3].

6.2.4.2 Wall thicknesses of pipes and sockets - non-circular The wall thickness of non-circular pipes and their sockets, including any outer layer, when measured at the location points as shown in Figure 3 shall be determined as follows: a) determine the internal cross-sectional area; b) round down to the next lower value in Table 1 and identify the corresponding circular nominal size; c) use the wall thickness values for pipes and sockets as defined in Table 2 for that nominal size, which apply only to the middle of the faces of the non-circular pipe and socket (see Figure 1). 6.2.5 Dimensions of sockets The dimensions of pipe sockets (see Figures 4
