Quality Assurance

Pipes are manufactured and tested in accordance with the standard SIST EN 1401-1: 2019 and SIST EN 13476-1, which requires continuous inspection of pipes.

Regular testing / own laboratory:

  • dimension control (outside diameter, wall thickness, headboard dimensions)

  • pipe layout control (color, pipe inscription)
    impact resistance

  • circumferential stiffness of the pipe

  • softening point temperature (according to Vicat)

  • tightness of pipe joints and shaped pieces

  • pipe creep module

Periodic testing / external laboratory:

  • toughness of the pipe

  • dimensional stability of the pipe

  • sulphate ash content

  • dichloromethane resistance

  • resistance of the pipe to internal hydrostatic pressure

In parallel with internal testing, PVC pipes for street sewerage are regularly tested at external independent institutions (ZAG – Civil Engineering Institute of Slovenia), as evidenced by the issued test reports.

ST – CS d.o.o. has an established and properly maintained management system that meets the requirements of the ISO 9001 standard, which ensures high quality products and services.
