Asphalt Shingle Roof Fasteners

The 2001 Florida Building Code calls for attachment of Asphalt Shingles: [FONT=Times New Roman][size=2]
“where the basic wind speed per Figure 1606
is 110 mph (49 m/s) or greater, special methods of fastening
are required. Unless otherwise noted, attachment of
asphalt shingles shall conform with ASTM D 3161 (modified
to 110 mph) or M-DC PA 107-95.”
My question is: Prior to the adoption of the 2001 FBC what were the requirements for shingle attachments in the 110 mph areas? (And can this be found in the 1997 Standard Building Code?)

For those that may be curious - further research reveals that
the answer appears to be…

The 1997 Standard Building code called for 6 fasteners for each shingle for areas where the basic wind speed is 100 mph, but did not call for shingles meeting the ASTM D 3161 Class F standard.
