| Marking Test | Marking parameters like manufacturer's name, nominal sizes, country of manufacture, strength & standard mark are tested under this. Also a test for durability of marking is conducted. |
| Dimension Test | The attributes tested in this are Maximum and Minimum Outside and Inside Diameter, Length of conduit and uniformity of wall thickness. |
| Construction Test | The requirements specified under this test are that the inside and outside surface of conduit are reasonably smooth and free from burrs, flash and similar defects; and the edges over which the conductors or cables are likely to drawn does not damage the cable or conductor. |
| Mechanical Property | The tests conducted for mechanical properties are the bending test, compression test (during and after the load), Impact test and Collapse test. |
| Resistance to Heat | The diameter of impression should not exceed 2mm. |
| Resistance to Burning | Flame of the sample should have died out in less than 30 seconds after removal of the burner. |
| Electrical Characteristics Test | Electrical strength and Insulation Resistance are tested under this step. |
