how we can select PVC material for PVC insulation and PVC sheath if we need properties a)all at a time or b)in combinations such as for particular cable,
fire retardant
fire resistant
oil resistant
anti termite
anti rodent
low smoke
low helogen
Is there any particular criteria for selection???
iec 540 standard clause 8: value of force can be calculated by formula F = k * Sqrt(2* D * sigma - sigma square)
Where D = mean value of outer diameter of test piece.
