This document describes a method for storing data in a PDF file that correspond to the processing steps of printed products. This method has three parts: metadata identifying processing steps; limitations on the interaction between PDF graphics objects that are part of a processing step and other PDF graphics objects; limitations on PDF graphics objects in processing steps. This method is intended to be generic, i.e. not specific to packaging and labels. In addition, this document defines the following packaging- and label-specific groups of processing steps data: data corresponding to finishing steps, such as cutting, folding or glueing; braille; information panels; indications of physical dimensions; indications of intended positions of graphical elements; printed white, for example on transparent or metallic surfaces; printed varnish; primer; printing plate making.

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.

This document is published as a dual logo standard and is applicable for the explosion protection requirements for the construction, testing and marking for Group I Ex Equipment that can be an individual item, or be an assembly of multiple items of Ex Equipment and Ex Components forming mining machinery. The standard atmospheric conditions (relating to the explosion characteristics of the atmosphere) under which it can be assumed that Ex Equipment can be operated are: - temperature −20 °C to +60 °C; - pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and - air with normal oxygen content, typically a volume fraction of 21 %. This part of ISO/IEC 80079 applies for Ex Equipment and Ex Components with Explosion Protection Levels (EPLs) Ma and Mb. This document supplements and modifies the general requirements of IEC 60079‑0. Where a requirement of this document conflicts with a requirement of IEC 60079-0, the requirement of this document takes precedence. This document can be used for guidance on underground applications where firedamp or coal dust can be present, but which are not Group I mines, for example tunnels. This second edition cancels and replaces the first edition, published in 2016. This edition constitutes a technical revision. Refer to the Foreword of the document for a complete listing of the technical changes between edition 2.0 and the previous edition of the document.
