according to S.S.C. 244
Mechanical specifications 1.
Tensile strength not less than 150 bar.
Elongation on cut not less than 300%. 2.
length should not exceed 200 % for seals of not less than
50 Shore A.
This when the seals are exposed for 30 min tension. The
seals should not be enlongated more than 3% after 1 hour
of tension. 3.
If this test is carried out on seals which have been expesed
to temperature in an oven for 168 hours, the elongation
should not exceed 5% after tension. 4.
hardness: should not be less than 55 ± 3 Shore
A.
When measured on endurance gauge. 5.
dimension disparity:
Inner diameter: ± 3%.
Area of cross section ± 3%.
