What is BS EN 295-6 – VCP manholes and inspection chambers about?
Vitrified clay pipe (VCP) is a pipe constructed from a mixture of clay and shale that has been vitrified at a high temperature to produce a hard, inert ceramic. BS EN 295 is the European Standard that discusses vitrified clay pipe (VCP) systems for drains and sewers.
BS EN 295-6 is the sixth part of the multi-series, and applies to 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 the continuous low head of pressure.
Note 1: The specifiers/purchasers can select the components for vitrified clay manholes and inspection chambers according to their requirements.
Note 2: BS EN 295-6 does not apply to manhole tops and cover slabs.
Note 3: 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.
Who is BS EN 295-6 – VCP manholes and inspection chambers for?
BS EN 295-6 on VCP manholes and inspection chambers is useful for:
- Relevant government / municipal authorities
- Manufacturers and suppliers of vitrified clay pipes
- Product design / innovation teams
- Quality control / testing personnel
- The construction industry
- Builders / architects / real estate developers
- Contractors
- Civil engineers
Why should you use BS EN 295-6 – VCP manholes and inspection chambers?
VCP is commonly used in gravity sewer mains because of its long life and resistance to almost all domestic and industrial sewage.
BS EN 295-6 specifies details such as different strength classes and heights of sections. BS EN 295-6 also specifies the requirements for components used for joints, systems of joint dimensions, and the materials rubber, polyurethane, and polypropylene; used for joints.
BS EN 295-6 provides guidance on requirements for components for manholes and inspection chambers, crushing strength, dimensional tolerances, and durability of tightness.
In addition, durability, reaction to fire, dangerous substances, designation, marking, and evaluation of conformity are also discussed in BS EN 295-6.
Overall, BS EN 295-6 guides you with best practices for manufacturing high-quality sewage system components, which extends the life of a sewage system and reduces the need for costly dig-ups.
