Summary
The Swiss building accessibility standard includes hearing systems and distinguishes technical design from the laws that determine where it applies.
Key findings
- The preview states approval on 4 September 2008 and validity from 1 January 2009, replacing SN 521500:1988. Its printing history gives January 2009 for the first printing.
- The contents identify section 7.8 on hearing systems and Annex F on their characteristics.
- The foreword says federal, cantonal and municipal laws determine where accessible building is required, while this standard defines how to design it.
- The preview is from the September 2022 third printing, incorporating corrections C3 and C4; it also lists a June 2011 reprint incorporating C1 and C2.
Limits
Only the publisher preview was read. Sections 7.8 and Annex F are listed but their requirements are absent. No hearing-system change is inferred from the correction or printing dates. The record date is the explicitly stated validity date.
