Description of the test |
|
Determination of Dimensions |
TS EN ISO 3126 |
Measuring and assesment the geometric properties of pipes for compliance with the relevant pipe production standards and customer technical specification requirements. |
|
Determination of Longitudinal Reversion |
TS EN ISO 2505 |
This is a testing method which shows the level of deformation the plastic pipes have been subjected to under changes of temperature. The rate at which the pipes, which have been subjected to the effects of heat for certain periods, are able to regain their former shape in full, is determined. |
|
Determination of Tensile Properties |
TS EN ISO 6259-1
TS EN ISO 6259-3 |
The traction test is a test which is carried out with the purpose of applying a tensile stress to the test sample of polymer, metallic and composite materials, on a single axis, at a certain speed and at a fixed temperature, in order to obtain information concerning the mechanical properties under this stress. Mechanical properties such as % elongation, tensile strength, yield strength of the material is determined as a result of this test. |
|
Determination of Resistance to Internal Pressure (Fittings) |
TS EN ISO 1167-1
TS EN ISO 1167-2 |
The hydro-static pressure test is an indicator of whether the pipes and piping joinery parts adhere to their expected lifespan. The test samples are subjected to hydro-static internal
pressure at pre-determined temperatures and levels of pressure and for pre-determined periods of time, and the samples are expected to complete the determined testing times in accordance with the standards. |
|
Determination of Carbon Black Content |
TS ISO 6964 |
Solar rays both change the appearance of plastic materials and reduce their mechanical properties. With this test, it is ensured that the rate of the carbon black filling material added to the plastic materials to protect against the impact of UV, can be determined. |
|
Determination of Pigment or Carbon Black Dispersion |
TS ISO 18553 |
This is a testing method implemented in order to determine the size and distribution of the pigments or carbon black and agglomerates within polyolefin pipes, their joining parts and granules. The samples which have been prepared are examined underneath the microscope and the homogeneity of the sizes and distributions of the granules and agglomerates are measured and categorised according to the classification system given in the relevant standard. |
|
Determination of Melt Mass Flow Rate (MFR) |
TS EN ISO 1133-1
(Metot A) |
The melting flow index is the measure of the amount of the flow of the material flowing from a mould of a certain length and size, at a specific volume and temperature, during the required period. The MFR value varies according to the chain length and density values of the material. It plays an important role in the determination of the parameters in the processing and welding processes of the materials. |
|
Determination of Oxidation Induction Time (OIT) |
TS EN ISO 11357-1
TS EN ISO 11357-6 |
This is a test which is conducted in order to determine the thermal stability of the plastic material at high temperatures and concentrated levels of oxygen. The test samples are kept within a flow of oxygen, at a specific temperature, and the time which passes until oxidation begins in the material which is present together with antioxidants, stabilisers
and the supplement system which contains the other materials. |
|
Determination of Density |
TS EN ISO 1183-1
(Metot A) |
The density value in plastic materials varies according to the chain structure of the material. Density provides information concerning the class and degree of crystallinity of a material. As the crystallinity rate increases, the density and resistance values of the material also display an increase in general. |
|
Determination of Volatile Content |
TS EN 12099 |
This ensures that the contents of the volatile substances applied to the components used in the casting and extrusion materials and the polyethylene pipe systems, and which are contained within the materials, are determined. |
|

|
Determination of Tensile Strength and Failure Mode |
TS ISO 13953 |
This is a testing method used in order to determine the tension resistance of butt welded pipe systems, the determination of the type of tension damage and the evaluation of the quality of the butt welded connections. |
|
Crushing Decohesion Test for PE Electrofusion |
TS ISO 13955 |
The resistance to separation of the polyethylene (PE) electro-fusion of the pipe sockets and saddles, are used in the distribution of liquids and which have a nominal diameter of between 16 mm – 225 mm, are determined. It is defined with the damage structure on the plane of the molten material of the separation resistant test sample and the percentage rate of separation. The appearance and location of the damage is taken into consideration in the evaluation of the resistance to separation of the test sample. |
|
Peel Decohesion Test of PE Electrofusion |
TS ISO 13954 |
The resistance to separation of the polyethylene (PE) electro-fusion couplings and bearing caps, which are used in the distribution of liquids and which have a nominal diameter of 90 mm or more, are determined. It shows the compliance of the quality of the welding of the pipes and piping joinery parts, which have been bonded by welding, in the welded areas. It is an important test which shows the compliance of the welding parameters of the electro-fusion type fittings. |
|
Decohesion Test of Polyethylene (PE) Saddle Fusion Joints |
TS ISO 13956 |
As with the Resistance to Separation Test, this test also shows whether the endurance of the welded areas of the pipes and piping joinery parts, which have been bonded through electro-fusion welding, is sufficient. It is an important test which shows the compliance of the welding parameters of the electro-fusion type fittings. |
|
Polyethylene (PE) Tapping Tees |
TS EN 1716 |
This is a method used in order to determine the resistance of Ts with a PE Perforator to an impact. Impact is applied in opposite directions, parallel to the main axis of the pipe and it is checked to see whether there is any damage on the Ts, and whether any air has seeped out. |
