The National Aerospace Standards (NAS) committee, overseen by the Aerospace Industries Association (AIA), published NAS523 to harmonize sampling procedures with MIL-STD-105 (the defunct military standard) while adding aerospace-specific modifiers.

The NAS523 specification is the aerospace standard for . Specifically, it dictates the head markings and codes used to identify blind rivets and solid rivets in aircraft construction. Because structural integrity is paramount in aviation, knowing how to interpret these markings is a critical skill.

When working with these standard practices, structural mechanics must cross-reference the symbol with standard aircraft calculations:
