18、aphy9 CEN/TS 14758-3:20063 Foreword This Technical Specification (CEN/TS 14758-3:2006) has been prepared by Technical Committee CEN/TC 155 “Plastics piping systems and ducting systems”, the secretariat of which is held by NEN. This Technical Specification is a Part of a System Standard for plastics
19、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 In
20、ternational 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
21、. EN 14758 consists of the following Parts, under the general title Plastics piping systems for non-pressure underground drainage and sewerage Polypropylene with mineral modifier(s) (PP-MD) Part 1: Specifications for pipes, fittings and the system Part 2: Guidance for the assessment of conformity Pa
22、rt 3: Guidance for installation (this Technical Specification) According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finlan

CEN/TS 14758-3:20064 1 Scope This Technical Specification, together with ENV 1046 and
24、 EN 1610, provides a material-specific set of guidelines for the installation of piping systems made of polypropylene with mineral modifier(s) (PP-MD) in the field of non-pressure underground drainage and sewerage. outside the building structure (application area code “U“); both buried in ground wit
25、hin the building structure (application area code “D“) and outside the building. This is reflected in the marking of products by “U“ and “UD“. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cite
26、d applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

When loaded a flexible pi
28、pe deflects and presses into the surrounding material. This generates a reaction in the surrounding materials which controls deflection of the pipe. The amount of deflection, which occurs is limited by the care exercised in the selection and laying of the bedding and side fill materials. 3.2 Pipes 3
29、.2.1 Standard procedure The choice of the stiffness (SN) series may be made: when the same class of pipe has previously proved to be satisfactory in the same condition; or based on local practice (place of installation, usual installation procedure and experience); or based on local regulation; or b
30、ased on Tables 1 and 2 of ENV 1046:2001; or based on structural design. CEN/TS 14758-3:20065 3.2.2 Structural design If a static calculation is required, information on methods is given in EN 1295-1 and the following parameters apply: Flexural modulus: E(1min) 1600-3600 MPa determined in accordance
31、with EN ISO 178 depending on the compound; Creep ratio: 200 mm: R 500dn. Care may be necessary to avoid any extra stress on the socket joint itself. The greatest permitted angular deflection in the socket should be as follows: 2 for dn 315 mm; 1,5 for 315 mm 630 mm. Larger angular deflections are pe
32、rmitted in case of joints specifically designed for large angular deflections. In these cases the manufacturer shall declare the designed angular deflection. CEN/TS 14758-3:20067 NOTE Approximately h L2/2R and L/R ( in radians). Figure 1 Parameters of deviation from straightness 8 Connection to rigi
33、d structures Special fittings for this purpose are available. In such cases the manufacturers instructions should be followed. 9 Repairs Slip-couplers or purpose-designed special fittings are available from manufacturers for effecting repairs. Because designs vary, it is necessary to follow individu
34、al manufacturers instructions. However, in the absence of such instructions, it is recommended that the following instructions are used: a) full extent of the damaged or failed section shall be identified and removed; b) cut pipe ends shall be square and shall be prepared for push-fit jointing as de
35、scribed in 6c); c) repair, or slip-, couplings shall be placed in position. The replacement pipe length shall then be laid on the suitably prepared bed and the slip-couplings moved to their final positions (see Figure 2); d) embedment shall then be replaced to give compaction values approximately eq
36、ual to those immediately adjacent to the repair. Figure 2 Repairs using slip-couplers CEN/TS 14758-3:20068 10 Connection to existing pipes For PP-MD pipelines an additional connection can be made in a manner similar to that for making a repair when an appropriate fitting is used. Alternatively, a sa
37、ddle connection may be made, in which case the manufacturers instructions should be followed. 11 Testing on site PP-MD non-pressure pipelines shall be tested according to the procedures described in Clause 13 of EN 1610:1997. PP-MD pipes are not porous, therefore it is possible to use more stringent
38、 parameters and requirements. In this case, the following are proposed: a) testing with air: 1) testing method : LC; 2) test pressure : 100 mbar (10 kPa); 3) pressure drop : 5 mbar (0,5 kPa); 4) testing time : 3 min for dn 400 mm; 0,01dnmin for dn 400 mm. b) testing with water: 1) 0,04 l/m2during 30
39、 min for pipelines; 2) 0,05 l/m2during 30 min for manholes and inspection chambers.
