NATIONAL BUTTON SOCIETY
SECTION 9-A SYNTHETIC POLYMERS HANDBOOK
NOW SECTION 12
Due to extensive revision and alphabetizing of the NBS
Classification, section and class numbers have changed. Old and new section and class numbers for
Synthetic Polymers are listed as follows:
Section 9-A = Section 12
Class 170 = Class 12-0
Minor numbering changes will continue as adjustments are made
so one should refer to the most recent NBS Classification Guide for up-to-date
class numbers.
