The Online Browsing Platform is a platform created by ISO that allows you to search and access our standards online. On the OBP you can freely preview parts of the standards (Foreword, Introduction, Scope, Normative references or Terms & definitions). This can help you decide whether it is the right standard you are looking for. The OBP is also used to access and purchase Graphical Symbols & Symbol Collections, Country Codes, Terms & Definitions.
