Use guidelines:

ISO's logo and short name

For anyone who is not an ISO member or a member of an ISO technical committee, here are some general guidelines to help you avoid misusing ISO's trademarks. (ISO members and ISO TCs should refer to ISO policies for specific guidance.)

ISO logo

  • Don't use or copy the ISO logo.

  • Don't modify or change the ISO logo.

  • Don't use a modified or changed ISO logo.

ISO short name

  • Don't register "ISO" as, or in, your domain name, website, or company name, e.g. www.isodatabase.com.

  • Don't use "ISO" as, or in, your product or service name.

  • Don't say that you, your products or your services are endorsed, approved or certified by ISO. (Remember, ISO doesn't perform certifications.)

  • Do refer to ISO or the International Organization for Standardization in a fair and appropriate way.

  • Do refer to ISO standards with their full reference, e.g., "ISO 9001:2015".
