5. TEST
The seal shall be tested at the manufacturer’s works for the following tests:

1 Visual Check:
l. e. workmanship and other features as mentioned above.

2 Dimensional Check:
as per Drawing.

3 Boiling water test:
The seal shall be emerged in the boiling water for more than one hour and there shall not be any affect on the seal and the seal shall remain in tact condition. Even, with the help of any sharp instrument, pulling with puller i.e. by applying mechanical force, the seal shall not come out from the female part.

6 Temperature withstand test:
The seal withstand 147 o C for one hour without any damage of deformation.

7 Specific Gravity:  Specific Gravity at 27 o C is 1.20.

8 Melting temperature: 
Melting temperature of the material is 280o C to 295o C.
