4、 8308: 1966-03, 1973-10, 1981-02 DIN ISO 1413:2017-07 3 ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees.
5、 Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Interna
6、tional Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the differ
7、ent types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall

10、ee the following URL: Foreword Supplementary information .The committee responsible for this document is ISO/TC 114, Horology, Subcommittee SC 1, Shock resistant watches.This third edition cancels and replaces the second edition (ISO 1413:1984), which has been technically revised with the following
11、changes:a) added a third shock on the watch head (on the crown);b) added two free-fall shocks, including the bracelet.DIN ISO 1413:2017-07 4 IntroductionThis International Standard is intended to allow the homologation test of watches rather than the individual control of all watches of a production
12、 batch. Indeed, assuming that each watch could comply with the minimum requirements without apparent damage, readjustment could still be made necessary because the test can lead to an alteration of the initial functions and rate of a complete watch.DIN ISO 1413:2017-07 5 1 ScopeThis International St
13、andard specifies the minimum requirements for shock-resistant wrist watches and describes the corresponding test method.It is based on the simulation of the shock received by a wrist watch while falling from a height of 1 m onto a horizontal wooden floor (an equivalent surface is described in B.1.1)
