SCITEQ SIGMA pressure solution determines the resistance (both long term and short term) to internal pressure on thermoplastic pipes, fittings and assemblies for conveyance of fluids,
complying with following test standards and equivalent:

  • ISO 1167 and ASTM D1598 long term hydrostatic test. Max. flow rate per station is 2 l/min.
  • ISO 1167 and ASTM D1599 short term testing”Standard Test Method for Time-to-Failure of Plastic Pipe Under Constant Internal Pressure”. Max. allowed pressuring time is 70 seconds Max. flow rate in a burst station is 15 l/min.

SIGMA PowerPack module         

Pressure source feed to all  SUB (pressure) modules with 5 or 10 pressure outlets. The pressure outlets  are seamlessly performing static, step and burst testing used for both R&D purpose and batch release testing. Various models available incl./excl. output for optional BURST modules. With built-in high pressure pump and 10 micron inlet filter.

  • Max. 100 or 160 bar regulated pressure output.
  • Max. 200bar unregulated output (optional)
  • Max. flow: 17 l/min.


SIGMA SUB module         

Provides 5 or 10 independently operating pressure stations up to max. 100 or 160 bar. Semi-automatic individual pressure transmitter calibration through integrated main transmitter is optional. Built-in fast reacting valves for precise pressure control.

  • Max. 100 or 160 bar regulated pressure  output
  • Max. flow per station: 2 l/min.



Provides one linear burst pressure station up to max. 200bar within 60-70 seconds. Built-in fast reacting high flow and pressure valves for fast and precise pressure control. Requires PowerPack module with output for BURST module.

  • Max. 200bar regulated pressure output
  • Max. flow: 15l/min.


SIGMA HCP3 module

Provides three independently high volume operating pressure stations up to max. 100bar regulated pressure output. Built-in fast reacting valves for precise pressure control.

  • 3 individual stations
  • Max. 100bar
  • Max. flow: 15 l/min


    DPCS – Dynamic Pressure Control System

    SCITEQ’s intelligent Dynamic Pressure Control System ensures that test pressures are maintained with unparalleled accuracy no matter what size sample is connected to the system. Static, burst and step testing can all be accommodated.

    Flow per station: max. flow 2 l/min (max. flow 15 l/min for burst). For other valve flow and power pack flow configurations, refer to the SCITEQ HCP solutions.


    The built-in alarm light instantly alerts the operator visually in case of irregularities in the ongoing test.


    The browser-based SIGMA software is accessible from any device – any time, anywhere. The advantages are among others:

      • 4 different user levels
      • Easy recipe set-up
      • Dynamically adjusted real-time finish time
      • Multiple simultaneous users
      • Multiple specimen test per station
      • SQL database compatible with all server types
      • PS UA enabled

      The fast and extremely easy to use interface enables easy operation and control of few as well as many simultaneous pressures tests with features such as dynamically adjusted finish time, full station overview and click less maneuvering.

      Recipes are quickly set-up, saving time when starting up a new test (diameter) as well as repeating saved test parameters. Up to four different user-levels from Basic to Advanced, ensuring not only easy operation, but also offering simultaneous ‘view-only’ access for your interested partners and clients.
