ANSI/ADA Specification No. 32-2000
Orthodontic Wires
This specification pertains to all metallic wires as components of fixed, intra-oral, orthodontic appliances with exception of (metallic) ligatures. In 1999, ANSI/ADA Specification No. 32 - 1977 for Orthodontic Wires Not Containing Precious Metals was withdrawn from the ASC MD156 work program as an outdated specification. The Working Group 1.7 Orthodontic Materials of Subcommittee 1 of ADA SCDP reviewed ANSI/ADA Specification No. 32, DIN 13970 and AS 1964-1977. The majority of the working group could not accept either the DIN or the AS as presently constituted and developed this new revised specification.
