This document specifies a procedure for evaluating the water resistance retention percentage, by comparing the sun protection factor (SPF) before water immersion (hereafter referred to as the \u201c static\u201d SPF) and after a fixed period of water immersion (hereafter referred to as the \u201cwet\u201d SPF).<\/p>\n
