This document specifies the procedure for evaluating the accuracy of quartz watches, individually and by lots (see Annex A which presents the methods for statistical evaluation of accuracy by lot), and the relationship between the accuracy tested and the accuracy classification given by the manufacturer.<\/p>\n
It applies to quartz watches having accompanying documents on which the accuracy classification is indicated.<\/p>\n
