BS EN 16506:2014

This standard BS EN 16506:2014 Systems for renovation of drains and sewers. Lining with a rigidly anchored plastics inner layer (RAPL) is classified in these ICS categories:

• 23.040.05 Pipelines and its parts for external sewage systems
• 23.040.45 Plastics fittings
• 93.030 External sewage systems
• 23.040.20 Plastics pipes
• 23.040.99 Other pipeline components

This European Standard specifies performance requirements and test methods for pipes and fittings for the renovation of underground drain and sewer systems by lining with a single rigid annulus of structural cementitious grout formed behind a plastics inner layer. This plastics layer serves as permanent formwork anchored to the grout. It is applicable to plastics inner layers and grout systems with or without steel reinforcement.

This European Standard does not apply to the structural design of the lining system.

NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this European Standard.
