Standards catalogue

ISO has developed over 21000 International Standards and all are included in the ISO Standards catalogue.

There are three ways to find the standard you are looking for:

  1. You can browse by ICS (International Classification for Standards). ICS is a way of classifying standards into fields such as electrical engineering or paper technology.
  2. You can browse by TC (technical committees). ISO standards are developed by experts from TCs focusing on all kinds of different subjects from screw threads to shipping technology. By clicking on the TC you can see all the standards published by this group of experts.
  3. You can search the standards catalogue using a key word or the number of the standard (all ISO standards are numbered) for example ‘quality management’ or ‘9001’ to find ISO 9001.


The Online Browsing Platform (OBP) lets you search and preview ISO Standards.
