What is BS EN 295-3 - VCP systems for drains and sewers test methods 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 295-3 is a European Standard that discusses VCP systems for drains and sewers.
BS EN 295-3 is the third part of the series, and specifies requirements for testing 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
Who is BS EN 295-3 - VCP systems for drains and sewers test methods for?
BS EN 295-3 on VCP systems for drains and sewers test methods is useful for:
- Manufacturers and suppliers of vitrified clay pipes
- Construction industries
- Civil engineers
- Product designers / innovation teams
- Building contractors
- Testing laboratories
- Manufacturers of construction products and building elements
Why should you use BS EN 295-3 - VCP systems for drains and sewers test methods?
VCP is commonly used in gravity sewer collection mains because of its long life and resistance to almost all domestic and industrial sewage, particularly the sulfuric acid that is generated by hydrogen sulfide, a common component of sewage.
BS EN 295-3 provides guidance on straightness, crushing strength, acceptance (proof), ultimate, bending tensile, and bending moment resistance (BMR) test.
VCP systems for drains and sewers test methods provided in BS EN 295-3 include:
- Tests for fatigue strength
- Tests for resistance to high pressure jetting
- Tests for material requirements of polypropylene sleeve couplings
- Chemical resistance
- Mechanical test methods for joint assemblies
In addition, durability, reaction to fire, dangerous substances, designation, marking, and evaluation of conformity are also discussed in BS EN 295-3.
Overall, BS EN 295-3 aids you in the creation of the main component by making its raw materials environmentally friendly. This enables more aggressive cleaning procedures, which extends the life of a sewage system and reduces the need for costly dig-ups.
What’s changed since the last update?
BS EN 295-3:2012 supersedes BS EN 295-3:1991, which is withdrawn. BS EN 295-3:2012 includes some technical and editorial changes with respect to BS EN 295-3:1991. These include:
- Test method for resistance to high-pressure water jetting added
- Test method for water absorption added
- Test methods from the previous parts 4, 5, 6, and 7 have been included in this European Standard
- Editorially revised
