Pars Sanjeh laboratory
Established in 1980, the Yazd Poolica’s laboratory was rehabilitated by purchase of the most advances equipment from well-known European producers during the implementation of Company’s development project in 2008. In 2013, the laboratory was named “Pars Sanjesh” and continued its activities as an independent body, having its own personnel. Since then, it is responsible for providing research and lab services, improving science and technology in polymer industry and relevant industries. Having a wealth of highly professional and experienced staff as well as unique research equipment, Pars Sanjesh is now recognized as one of the most advanced professional laboratories in pipes and fittings industry, which provides services in accordance with national and international standards.
The Laboratory is able to implement any physical, mechanical, chemical and plastic product analysis tests, particularly in polymer pipe and fitting areas. Pars Sanjesh laboratory has a high capacity for implementing all tests on a wide range of U-PVC pipes and fittings with an application in water supply, drainage and sewage pipes, rainwater transport pipes, electrical and telecommunications conduits, and pipes and fittings used in agriculture sector (for wells, under pressure and normal irrigation, and drainage).

example of tests conducted on pipes an fittings and their raw materials in the laboratory
Impact resistance test:
This test is performed according to the test method with ISIRI number 11438 and DIN EN 744. This device is capable of performing tests for pipes with a nominal outer diameter of 25 to 650 mm and with weights from 0.5 to 6.300 kg and a height of 2 meters. It is also possible to set the samples to minus 20 degrees Celsius at different times before performing the test.
Pendulum Impact Test:
Pendulum impact test is to obtain the refractive energy of a material due to dynamic stress. It is basically to determine the impact resistance. This device is suitable for quality control of raw materials and parts and research. Impact testing is a good criterion for determining and classifying the tendency of different plastics for brittle behavior.
Ring stiffness test:
This test is performed according to the test method numbered INSO 11436 and ISO 9969. Which indicates the amount of additional external loads on the pipe. On the sample, the device applies a force of 3% of the deformation of the outer diameter to the pipe and shows the force in terms of deformation in different axes of the sample. The unit of ring stiffness is declared in KN / M2.
Tensile strength test:
This test is performed according to the test method numbered INSO 17140 and ISO 6259. This equipment can be stress, strain, elongation, tear, peel, shear, yield point, elastic modulus, Bending modulus and…. To measure. First, the sample is made by CNC machine according to its thickness in three different types; It is machined with special care and then the sample is tested by the machine and finally the stress-strain diagram, which shows the physical and mechanical properties of the product.
Hydrostatic pressure test:
This test is performed according to the test method with ISIRI number 12181 and ISO 1167. The hydrostatic pressure testing device of this laboratory has the ability to perform 5 tests simultaneously and up to 100 bar pressure. Testing can be done at temperatures of 20 and 60 degrees Celsius and strengths for a long time of 1000 hours, and also after the end of the test, the device will give us the graphs related to the relevant pressure and time.
Longitudinal reversal test:
This test is performed according to the test method numbered INSO 17614 and ISO 2505 using an oven. Up to a temperature of 250 ° C and dimensions of 60 × 100 ۰۰ 100 cm.
This device is made with the German brand RAYRAN and in accordance with the test method number ISIRI 6982. Which determines the temperature of the softening point and thermal bending of polymer products. This test is used to measure the ability of polymers to maintain mechanical properties (surface properties) at high temperatures. Because polymeric materials are being replaced by other materials in all fields, the importance of performing this test is increasing rapidly and rapidly.
Ash percentage test:
According to the test method, INSO numbers 10237 are performed using an electric oven with a temperature capability of 1200 ° C. The percentage of minerals and organic matter in the final product is determined. Which is tested at a temperature of 950 degrees Celsius.
This test is performed according to the test method to INSO 7090 numbers, which determine the density of the polymer product part.
Determination of polymer viscosity:
This test is performed according to the standard number ISIRI 13249 and ISO 1628 and is determined by K-VALUE device, which is one of the most unique devices in this series with the German IPT brand. This device uses capillary viscometers to determine the grade of PVC powder and determine the viscosity of polymers.
Powder shedding speed:
This test is performed under test number ASTM D 1895. This test determines how the PVC powder and compound fall off, and the result of this test for the compounds shows the desirability of the mixing process for PVC.
This device has the ability to simulate the production process. Which is to optimize the formulation of various polymer samples and research projects. Using the samples taken, the physical and mechanical properties of various polymeric materials can be investigated.
Using this device, we can study the formulation and blending on a laboratory scale.
To determine the opacity of polymer products.
Particle size determination:
Using this device, we can measure the particle size of materials such as calcium carbonate.
