  of the long-term crushing strength (50 years evaluation
  point) of a chamber ring or a shaft ring, including the
  effects of media attack
Bibliography

Describes units made from polyester resin concrete (PRC), and their joints, for the construction of inspection chambers with inverts not exceeding 2 m deep and for manholes, intended to be used within a drain or sewer system operating without pressure.
