1.1 ,This test method covers the procedure for determining the chemical-resistant properties of fiberglass pipe in a deflected condition for diameters 4 in. (102 mm) and larger. Both glass–,fiber–,reinforced thermosetting resin pipe (RTRP) and glass–,fiber–,reinforced polymer mortar pipe (RPMP) are fiberglass pipes.
Note 1: ,For the purposes for this standard, polymer does not include natural polymers.
