This National Standard of Canada is based on International Standard CEI/IEC 335-2-20:1984. 1. Scope This clause of Part 1 is applicable except as follows: 1.1 Replacement: This standard applies to rechargeable battery-powered motor-operated tooth-brushes for household and similar purposes, and to their charging and battery assemblies where recharging is accomplished by connecting the charging assembly to the supply mains. This standard does not take into account the special hazards which exist in nurseries and other places where there are young children or aged or infirm persons without supervision; in such cases, additional requirements may be necessary. This standard does not apply to: - tooth-brushes intended to be operated directly from the supply mains; - tooth-brushes for medical purposes. For tooth-brushes intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary. For tooth-brushes intended to be used in tropical countries, special requirements may be necessary. Attention is drawn to the fact that in many countries additional requirements are specified by the national health authorities.
