Laboratory of Plastic pipeline Systems and Facilities

SCOPE OF LABORATORY ACTIVITIES:

	testing of pressure piping systems for the supply of potable water, hot and cold water for sanitary systems, floor and central heating (PE, PE-X, PP, PVC-U, PB, ABS, multilayer pipes etc.)
	testing of plastics piping systems for the supply of gaseous fuels
	sewerage systems for (gravitational, vacuum and pressure systems), manholes, covers, ancillary fittings
	glass reinforced piping systems
	pipes for drainage
	piping systems for soil and waste discharge (low and high temperature) within the building structure
	eaves gutters and fittings for roofs
	channels with covers for telecommunications
	couble throughes and cover plates
	plastic and rubber hoses
	covers, floor traps, siphons, toilet cisterns
	plastic and metal valves, sanitary tapware, single and mixer taps
	sealing components (sealands, teflon tapes, o-rings etc.)

TESTING - SURVEY OF CHOISEN CHARACTERISTICS

	long-term hydrostatic strength according to ISO 9080
	hydrostatic strength at constant pressure (EN 921, ISO 1167), valves, fittings and systems ( mechanical, welded, cemented, …. joints)
	tightness of pressure systems under pressure cycling, temperature cycling and vibration
	tightness of sewerage (video), waste and eaves systems
	resistance to slow crack growth (notch pipe test, cone test)
	abrasion tests of sewerage pipes (Darmstadt test)
	determination of long term creep and relaxation factors under wet and dry conditions, creep and relaxation behaviour of materials (tensile, flexural, …), long term welding factors etc.
	fatigue tests (toilette cisterns, mixer taps, fatigue strength of valves etc.), hydraulic properties
	resistance to elevated temperature cycling of floor traps, siphons and other ancillary fittings
