ISO/TC 114/SC 12 - Antimagnetism

This document specifies the minimum requirements and test methods for magnetic resistant watches. This document applies to magnetic resistant watches designed to withstand daily magnetic fields. Moreover, it indicates the marking which the manufacturer is authorized to apply to them.

ISO 764 specifies the minimum requirements and test methods for magnetic resistant watches. It is based on the simulation of an accidental exposure of a watch to a direct current magnetic field of 4 800 A/m. Annex A deals with watches designated as magnetic resistant with an additional indication of intensity of a magnetic field exceeding 4 800 A/m.

Specifies the minimum requirements and describes the corresponding method of test. It based on the simulation of the accidental exposure of a watch to a macnetic field of 4800 A/m.
