EN 13980 is an EU (European Union) standard for companies that are looking to produce ATEX (EU Directive 94/9/EC and 99/92/EC) rated equipment. It’s based off ISO 9001, with specifics to components and products in explosives atmospheres. It is not a free standard but the cost is small and can be purchase at many different website, usally depending on the language (BSI for English).
For a company, such as Otis Instruments, that is looking to produce ATEX rated equipment two certifications are needed; and they are the Quality Assurance Notification (QAN) and the EC Type Examination Certificate. The Quality Assurance Notification is issued to a company that has had an assement audit for compliance to EN 13980. A EC Type Examination Certificate is a certificate issued for specific hardware that has passed testing from the ATEX standard (usually based of EN 16079, among others).
