Dentistry - External tooth bleaching products (ISO 28399:2026)
Scope:
This document specifies the 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) or both. It also specifies requirements for their packaging, labelling and manufacturer’s instructions for use.
This document is not applicable to tooth bleaching products:
- specified in ISO 11609;
- intended to change colour perception of natural teeth by mechanical methods (e.g. stain removal) or using restorative approaches, such as veneers or crowns;
- auxiliary or supplementary materials (e.g. tray materials) and instruments or devices (e.g. lights) that are used in conjunction with the bleaching products.
This document does not specify biological safety aspects of tooth bleaching products.
NOTE The maximum concentration of a bleaching agent for professional or non-professional use is subject to each country’s regulatory body.

Petroleum, petrochemical and natural gas industries -- Axial and centrifugal compressors and expander-compressors -- Part 1: General requirements
Scope:
ISO 10439 specifies minimum requirements and gives recommendations for axial compressors, single-shaft, and integrally geared process centrifugal compressors, and expander-compressors for special purpose applications that handle gas or process air in the petroleum, petrochemical, and natural gas industries. ISO 10439-1:2015 specifies general requirements applicable to all such machines.
ISO 10439-1:2015 does not apply to fans (these are covered by API 673) or blowers that develop less than 34 kPa (5 psi) pressure rise above atmospheric pressure. It also does not apply to packaged, integrally geared centrifugal plant, and instrument air compressors, which are covered by API 672. Hot gas expanders over 300 °C (570 °F) are not covered by ISO 10439-1:2015.
ISO 10439-1:2015 contains information pertinent to all equipment covered by the other parts of ISO 10439. It shall be used in conjunction with the following parts of ISO 10439, as applicable to the specific equipment covered: ISO 10439-2;
ISO 10439-3; ISO 10439-4
