CEN/TC 165/WG 2 - Vitrified clay pipes

This Technical Report gives guidance for the assessment of conformity of vitrified clay pipe systems for drains and sewers including pipes, fittings, manholes, perforated pipes, jacking pipes and associated products by the establishment of voluntary third-party certification procedures.
It is recommended that the quality management system conforms to or is no less stringent than the relevant requirements to EN ISO 9001.

This standard also specifies requirements for rubber, polyurethane and polypropylene materials and other components used for jointing clay pipes and fittings.
This standard specifies different strength classes, systems of joint dimensions, lengths and fittings.
NOTE 1   The specifiers/purchasers can select them according to their requirements.
This standard does not apply to special fittings, adaptors and compatible accessories, perforated pipes and fittings, manholes and inspection chambers and pipes and joints for pipe jacking, which are specified in other parts of the standard series EN 295.
NOTE 2   Corresponding provisions for the evaluation of conformity (ITT and FPC) and sampling and those for the test methods are further specified in EN 295-2 and EN 295-3, respectively.

This European Standard specifies requirements for the evaluation of conformity of products manufactured from vitrified clay and other materials (referred to as "products") specified in the following standards:

-   perforated pipes and fittings according to EN 295-5;
-   components of manholes and inspection chambers according to EN 295-6; and
-   pipes and joints for pipe jacking according to EN 295-7.

This European Standard applies for components for vitrified clay manholes and inspection chambers for buried drain and sewer systems for the conveyance of wastewater (including domestic wastewater, surface water and rainwater) under gravity and periodic hydraulic surcharge or under continuous low head of pressure.
It specifies different strength classes and heights of sections. It also specifies the requirements for components used for joints, systems of joint dimensions and the materials rubber, polyurethane and polypropylene used for joints.
NOTE 1   The specifiers/purchasers can select the components for vitrified clay manholes and inspection chambers according to their requirements.
This standard does not apply to manhole tops and cover slabs.
NOTE 2   Corresponding provisions for the evaluation of conformity (ITT and FPC) and sampling and those for the test methods are further specified in EN 295-2 and EN 295-3, respectively.

This European Standard specifies requirements for adaptors and connectors made from vitrified clay and/or other suitable materials for use with vitrified clay pipes and fittings for buried drain and sewer systems for the conveyance of wastewater (including domestic wastewater, surface water and rainwater) under gravity and periodic hydraulic surcharge or under continuous low head of pressure.
Adaptors and connectors include insertable fittings, sealing rings for cut pipes and heat-shrinkable sleeves.
This standard also applies for metal banded flexible couplings and adaptors and specifies requirements for rubber, polyurethane, stainless steel and other components used for them.
NOTE 1   The specifiers/purchasers can select adaptors, connectors and flexible couplings according to their requirements.
NOTE 2   Corresponding provisions for the evaluation of conformity (ITT and FPC) and sampling and those for the test methods are further specified in EN 295 2 and EN 295 3, respectively.

This European Standard specifies requirements for perforated pipes and compatible fittings made from vitrified clay with or without sockets for use in land drains and drainage of waste tips. They are also used for percolation into the ground.
This standard specifies different strength classes and areas of perforations.
NOTE 1   The specifiers/purchasers can select perforated pipes and compatible fittings according to their requirements.
NOTE 2   Corresponding provisions for the evaluation of conformity (ITT and FPC) and sampling and those for the test methods are further specified in EN 295-2 and EN 295-3, respectively.

This European Standard specifies requirements for vitrified clay pipes and joints for pipe jacking for buried drain and sewer systems for the conveyance of wastewater (including domestic wastewater, surface water and rainwater) under gravity and periodic hydraulic surcharge or under continuous low head of pressure. Pipe jacking techniques include micro-tunnelling, pipe-eating, pipe bursting and where appropriate lining with discrete pipes.
This standard also specifies requirements for rubber, polyurethane, polypropylene, stainless steel and other materials used for joints for pipe jacking.
NOTE   Corresponding provisions for the evaluation of conformity (ITT and FPC) and sampling and those for the test methods are further specified in EN 295-2 and EN 295-3, respectively.

This European Standard specifies requirements for testing of products manufactured from vitrified clay and other materials specified in the following standards:
   pipes, fittings and joints according to EN 295-1;
   adaptors, connectors and flexible couplings according to EN 295-4;
   perforated pipes and fittings according to EN 295-5;
   components of manholes and inspection chambers according to EN 295 6;
   pipes and joints for pipe jacking according to EN 295-7.

This standard specifies requirements for vitrified clay pipes, fittings and pipe joints for drains and sewers to be in conformance with the requirements of the Mandate M 118 "Waste Water Engineering Products" as well as the Mandate M 131 "Pipes, Tanks and Ancillaries not in contact with water for human consumption"
In this scope it applies to:
- vitrified clay pipes, fittings and pipe joints
- special fittings, adaptors and compatible accessories
- perforated vitrified clay pipes and fittings
- vitrified clay manholes and
- vitrified clay pipes and joints for pipe jacking
for drain or sewer systems for the conveyance of sewage and surface water (including rain water) under gravity or occasionally at low head of pressure.

Migrated from Progress Sheet (TC Comment) (2000-07-10): Amendment to the part 1

This standard specifies requirements for flexibly jointed vitrified clay pipes for the construction of pipelines by pipe jacking techniques including micro-tunnelling, pipe-eating, pipe bursting and where appropriate for slip-lining. Where this standard provides for different strength classes the specifiers/purchasers may select according to their requirments.

This Standard specifies the requirements for components for vitrified clay manholes and inspection shafts. These are for use with flexibly jointed vitrified clay pipes and fittings manufactured to EN 295-1. Where this standard provides different systems of jointing, different heights, different strength classes and different channels, the specifiers/purchasers may select according to their requirements. Note: Where reference is made to clauses in EN 295-1, EN 295-2 or EN 295-3 this is clearly stated.

This standard specifies the performance criteria for the internal pressure strength, the external pressure strength, the longitudinal bending strength, the crushing resistance, the tightness, the resistance to abrasion and the permeability to pollutants of pipes used for waste liquid (above all water) transport. This standard includes the corresponding test methods and the evalutation of conformity of the product to this standard.
