Test density( Unit for Determination of Density) Measure the density of the raw material, under the standard DIN 53 479 ASTM D 792 , BS 2782 , ISO 1183 and ISIRI 7175-2 done . The density of the products also in addition raw materials have to be measured . The method to do the same, measuring the density of the raw material . This test daily or in the event of a change in the conditions of the production line is done. Test pressure hydrostatic ( Hydrostatic Pressure tester ) Pressure test hydro-static pipes and fittings is one of the most testing products can be one of the essentials of standards, ASTM F 2389 , ISO 15874 , mature, ISIRI 6314 , DIN 8078 . To do this test the samples in accordance with the standards preparation . Then in the compartment that is water with a temperature of specified fill is placed . In continue, etc. set by the device pressure hydro-static pressure is specified . The method to do this test in accordance with the standards EN 921 , ISIRI 7175 and ISO 1167 . In this method, the tubes according to the table below under the test pressure placed. In each case, 3 samples should be tested in connection with recent events . If all the samples after the test time, without a bust, and failure. this test is acceptable . Test pressure bust ( Burst ) : Hydrostatic/Burst Tester ISO 1167 | ASTM D 1598 | ASTM D 1599
Measure the dimensions of Circometer Dial Caliper Guage/ Due to the importance of the dimensions (قطرخارجی, thickness, etc. circle واربودن sections. تلرانسها)steadily, according to the standards, ISIRI 7175-1 ,ASTM D 2122 , ISO 3126 by the caliper, the gauge, thickness gauge, by technicians, to be measured.If any departure from the range مجازمحصولات of-the-line packing, removal, and part waste of data transfer.These measurements are the maximum at intervals of one hour is done.
Test back Flex longitudinal : Oven
Measure the amount of back flexibility, longitudinal to the tubes, polypropylene, one other requirements of the standard DIN 8078 . The method to do this testing in accordance with IRISI 7175-3 ISO 3126 , ASTM D 2122 .In this test, the samples at a temperature of 135 degrees Celsius due to the thickness for the given time duration fall . After cooling. the amount of length change, so remain measurement the pipe should be 2% less . This test is conducted daily .
