Product Testing

Tests included in the Standard are:

  • Test proof load testing
  • Ultimate load testing
  • Water tightness (formerly known as hydrostatic testing)
  • Specified and ultimate pressure tests
  • Water absorption
  • Flexible joint assembly
  • Measurement of concrete cover to reinforcement
  • Measurement of dimensions other than concrete cover

Added to this, concrete pipe manufacturers have strict quality control procedures that are implemented to ensure the whole manufacturing process is accounted for. In particular this includes the mixing and batching of concrete, with appropriate aggregates, admixtures and binders, using:

  • Computer controlled weighing and proportioning systems
  • Computer controlled mixing systems
  • Automated recording systems.

The quality systems are also required to ensure that the welding of steel reinforcement into cages is carefully monitored and tested to ensure compliance.
