In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by EN 12201 (all parts): a) this European Standard provides no information as to whether the products may be used without restriction in any of the Member States of the EU or EFTA; b) products intended for use in water supply systems must comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water. NOTE On April 2006, EC Commission set up a revised mandate (M/136) asking CEN to propose harmonised product standards and support standards for test methods which could be used for assessing the fitness for contact with drinking water. In parallel, EC Commission has launched processes for a regulation of construction products (CPR) to be substituted to CP directive (89/106/EEC) and for the revision of drinking water directive (98/83/EC). If relevant, when the ouputs of these processes will be known, European Product Standards will be amended by the addition of an Annex Z under Mandate M136 which will contain formal references to the applicable requirements. Until such amendments, the current national regulations remain applicable. Requirements and test methods for material and components, other than fittings, are specified in EN 12201-1, EN 12201-2 and prEN 12201-4:2011. Characteristics for fitness of purpose are covered in EN 12201-5. CEN/TS 12201-7 [2] gives guidance for the assessment of conformity. This Part of EN 12201 covers the characteristics of fittings.

Any melt exudation shall not cause wire movement in electrofusion fittings such that it leads to short-circuiting, when jointed in accordance with the manufacturer’s instructions. There shall be no excessive creasing of the internal surfaces of the adjoining pipes. 5.6 Effect on water quality For fittings intended for the conveyance of water for human consumption attention is drawn to the requirements of national regulations (see Introduction). 6 Geometrical characteristics 6.1 Measurement of dimensions The dimensions of the fittings shall be measured in accordance with EN ISO 3126.

a D1 is measured in any plane parallel to the plane of the entrance face at a distance not greater than L2 (tubular length) from the plane of the entrance face. b This diameter does not include the fusion bead, if any. c It comprises the thickness measured at any point of the wall of the fitting. d It is measured at any point at a maximum distance of L1 (cut back length) from the entrance face and shall be equal to the pipe wall thickness and tolerance to which it is intended to be butt fused, as specified in EN 12201-2:2011, Table 2. E1 for small dimensions is at least 3 mm. e It comprises the initial depth of the spigot end necessary for butt fusion or re-weld and may be obtained by joining a length of pipe to the spigot end of the fitting provided the wall thickness of the pipe is equal to E1 for its entire length. f It comprises the initial length of the fusion end piece and shall allow the following (in any combination): the use of clamps required in the case of butt fusion; assembly with an electrofusion fitting; assembly with a socket fusion fitting; the use of a mechanical scraper.

20 20 a Tolerance grades A and B are in accordance with ISO 11922-1:1997 [8]. b The values of L2 (electrofusion) are based on the following equations:
for dn ≤ 90, L2 = 0,6dn + 25 mm;
for dn ≥ 110, L2 = dn/3 + 45 mm. c Used by preference. d Used for fittings fabricated in the factory.
6.4 Dimensions of socket fusion fittings For the description and dimensions of these types of fittings, see Annex A. 6.5 Dimensions of electrofusion saddle fittings Outlets from tapping tees and branch saddles shall have spigots in accordance with 6.3 or an electrofusion socket in accordance with 6.2. The manufacturer shall specify the overall characteristic dimension of the fitting in the technical file. These dimensions shall include the maximum height of the saddle, H, and the height of the service pipe measured from the top of the main, h, as shown in Figure 3. NOTE For technical and design reasons the minimum bore diameter D2 may be different from the one of spigot fittings as given in 6.3. SIST EN 12201-3:2011
Key H is the height of the saddle, i.e. the distance from the top of the main to the top of the tapping tee; h is the "height of service pipe", i.e. the distance between the top of the main pipe and the axis of the service pipe; L is the "width of the tapping tee", i.e. the distance between the axis of the pipe and the plane of the mouth of the service tee. Figure 3 — Dimensions of electrofusion saddle fittings 6.6 Dimensions of mechanical fittings Mechanical fittings manufactured substantially from PE and intended for part fusion to PE pipe and part mechanical jointing to other pipe components, e.g. adapters, shall in at least one joint conform to the geometrical characteristics of the PE jointing system to be used. NOTE Mechanical fittings not manufactured substantially from PE should conform to the requirements specified in the relevant standard(s). 6.7 Dimensions of loose backing flanges and flange adapters Dimensions of loose backing flanges and flange adapters shall be in accordance with ISO 9624. 6.8 Dimensions of fabricated fittings When the description and dimensions of fittings of this type are required, Annex B applies. 7 Mechanical characteristics 7.1 General A fitting shall be tested and assembled with pipe or as a part of an assembly of more than one fitting fused to pipe conforming to EN 12201-2.
