Hi William,
Thank you for contacting Hilti!
Different varieties of HUS3-H (carbon steel & Hot Dipped Galvanized versions) are approved for both C1 & C2. However, only sizes 8, 10, and 14mm are approved for seismic C2 when installed at the deepest tested embedment depth, hnom 3, as shown under Table C5 on page 26 of the approval document ETA-13/1038, which can be accessed through THIS LINK. Installation parameters for the sizes mentioned above are available under Table B2 on page 14 of ETA-13/1038.
I hope this helps. Please don't hesitate to reach out if you have any further questions.
Best regards,
Ask Hilti Team.
