Bulletin numbers are derived by assigning
a sequential number and then appending a dash and the year
of original issue. For example, bulletin “3-2000”
is the third bulletin published in calendar year 2000. The
date indicates the current version of the bulletin. Some gaps
exist in the list because certain Engineering Bulletins have
been withdrawn due to obsolescence as designs and regulations
change.
