DIN EN ISO 28399:2011-05

This standard specifies requirements and test methods for external tooth bleaching products. These products are intended for use in the oral cavity, either by professional application (in-office tooth bleaching products) or consumer application (professional or non professional home use of tooth bleaching products). It also specifies requirements for their packaging, labelling and instructions for use. This standard is not applicable to tooth bleaching products: - specified in ISO 1169; - those intended to change colour perception of natural teeth by mechanical methods (e. g. stain removal) or using restorative approaches, such as veneers or crowns; - auxilliary or supplementary materials (e. g. tray materials) and instruments or devices (e. g. lights) that are used in conjunction with the bleaching products.
