Frequently Asked Questions about ONR CEN/TS 17685-2
When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
If you have an extensive portfolio of standards, we recommend using a professional standards management tool. With effects 2.0, you can manage your standards centrally and efficiently. You can optimise your procurement processes and benefit from an integrated information and subscription service. This ensures you are always up to date and never miss any relevant developments.
