C Tables showing examples of basic stresses as a
function of the operating temperature TS, the time to
failure t and the chemical resistance factor fCR
D Examples of basic stress curves with water for
polyethylene pipes with a nominal stress sN = 8 MPa
E Examples of basic stress curves with water for
polybutene pipes with a nominal stress sN = 8 MPa
F Examples of basic stress curves with water for
propylene homopolymer pipes with a nominal stress sN
= 6.3 MPs
G Examples of basic stress curves with water for propylene
copolymer pipes with a nominal stress sN = 5MPa
Specifies the basic stress as reference value for determination of the series S of polyolefin pressure pipes and uses the classification of pipes in accordance with their nominal stress. ALSO NUMBERED AS BS ISO 8584/1
