16、commonly known as the ISO equation,6is used in thisspecification to relate standard dimension ratio, hydrostaticdesign stress, and pressure rating:2S/P 5 R 1 1or2S/P 5 Di/t! 1 1 (1)where:S = hydrostatic design stress, MPa (or psi),P = pressure rating, MPa (or psi),Di= average inside diameter, mm (or
17、 in.),t = minimum wall thickness, mm (or in.), andR = standard thermoplastic pipe dimension ratio (Di/t forPE pipe), also known as SIDR.3.2.4 standard thermoplastic pipe dimension ratio (SIDR)the ratio of pipe diameter to wall thickness. For PE pipe it iscalculated by dividing the average inside dia
