Specification

Test methods

1

Hardness of Outer Wall(Shore-D)

59

Sheath the 100mm length duct sample tightly around the metallic bar with a suitable outer diameter and put them just below the Hardness Meter of Shore-D. As per the method indicated in the GB/T 2411-1980 Standard, read the instant Hardness value is testing result. Totally read for 5 times, the average arithmetical value will be the final result.

2

Internal Co-efficient of Friction

0.12

Perform the testing according to the Appendix D of GB/T 24456-2009 Standard.

3

Tensile Strength at Yield

21MPa

Hold the sample on the tester respectively with the tensile speed of 100mm/min, till the 5 samples are broken off by the pulling force, make the note of the maximal tensile value as the testing results during the tensile process, the average arithmetical value of these 5 effective results will be the final result.

4

Elongation at break

380%

5

Max Pulling Load

12000N

Take the complete duct sample of 200mm length, both ends of sample should be cut neatly. Then use the special clamp to hold it onto the tester with  the tensile speed of  450mm/min till the sample yields, read the yield loading  as the testing result. Totally read for 3 times, the average arithmetical value will be the final result.

6

Bending Radius after cooling

1000mm

Place sample of 1.5m length at -20environment for more than 2 hours, and then take it out and put it onto the bending machine with 300mm radius within 1 minute to perform the testing of bending towards four directions, the surface of duct has no crack.

7

Ring Stiffness

30kN/m2

Perform the testing according to clause 6.5.2 of YD/T 841-1996 Standard.

8

Crush test

-

Crush the 200mm length sample at speed of 5mm/min till the deformation value of outer diameter is 50% of the original, remove the loading, the duct should not crack or layered.

9

Longitudinal Reversion

3.0%

As per the testing method B of GB/T 6671-2001 Standerd, the temperature of oven is 110.

10

Impact Strength

-

Place 10 sample of 150mm length at -30environment for more than 2 hours, and then take it out and drop a 15.3Kg hammer from 2.0 meters height to it within 30 seconds, the structure and size of hammer complies with the GB/T 24456-2009 Standard.

11

Air Pressure

1.6MPa
