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. |
