Plastics piping and ducting systems - Systems outside building structures for the conveyance of water or sewage - Practices for installation above and below ground ENV 1046:2001

Publication date:   Jun 30, 2004

Scope

This prestandard is applicable to the installation of plastics piping systems to be used for the conveyance of water or sewage under gravity and pressure conditions above and below ground. It is intended to be used for pipes of nominal size up to and including DN 3000.
Where in this prestandard the term "pipe" is used then it serves also to cover any "fittings", "ancillary" products and "components".
NOTE 1 It is assumed that additional recommendations and/or requirements are detailed in the individual materials System Standards. Instances where this is expected to apply include those indicated in this prestandard as follows:
a) any special transportation requirements (see 4.2.6);
b) maximum storage height (see 4.4.3 and 4.4.4);
c) maximum storage period in direct sunlight (see 4.4.6);
d) any climatic conditions requiring special storage (see 4.4.7);
e) limiting initial and/or long-term deflections (see 5.1.1 and 5.1.2);
f) information on mole ploughing and boring (see and 5.2), if applicable;
g) longitudinal tensile modulus and strength (see 5.3.1.2);
h) coefficient of thermal linear expansion (see 5.3.2.2 and Annex B);
i) suitability for use in areas exposed to sunlight (see 5.3.3);
j) selection of appropriate jointing system (see clause 6);
k) recommended radii of curvature for cold bending (see 7.1);
l) permitted rates of loss of water under test (see 8.2.1);
m) if applicable the relationship between SDR and stiffness.
NOTE 2 Guidance and instructions concerning commissioning of systems can be found in the standards prepared by CEN/TC 164 and by CEN/TC 165 and the relevant national and/or local regulations.
NOTE 3 Concerning the character of this document see Foreword and Introduction.
