4、evels.Guidance for installation offiberglass pipe in subaqueous conditions is not included.1.2 Product standards for fiberglass pipe encompass a widerange of product variables.Diameters range from 1 in.to 13 ft(25 mm to 4000 mm)and pipe stiffnesses range from 9 to over72 psi(60 to 500 kPa)with inter
5、nal pressure ratings up toseveral thousand pound force per square inch.This standarddoes not purport to consider all of the possible combinations ofpipe,soil types,and natural ground conditions that may occur.The recommendations in this practice may need to be modifiedor expanded to meet the needs o
6、f some installation conditions.In particular,fiberglass pipe with diameters of a few inches aregenerally so stiff that they are frequently installed in accor-dance with different guidelines.Consult with the pipe manu-facturer for guidance on which practices are applicable to theseparticular pipes.1.
7、3 Thescopeofthispracticeexcludesproduct-performance criteria such as a minimum pipe stiffness,maxi-mum service deflection,or long-term strength.Such param-eters may be contained in product standards or designspecifications,or both,for fiberglass pipe.It is incumbent uponthe specified product manufac
