All of the National Standards contained within this Volume are first editions. However, due to renumbering, CSA Standard CAN/CSA-Z349.38, Dental Alginate Impression Material, supersedes CSA Standard CAN3-Z349.6 originally published in 1982. This volume, in conjunction with Filling, Restorative, and Prosthodontic Materials for Dentistry— Volume 1, is intended to provide a complete collection of the ISO Standards for dental materials available at the time of publication. Future ISO documents in this area will be considered for adoption as National Standards of Canada for publication as Volume 3. This Volume is a component of the Series of CSA Standards on Dentistry which addresses subject areas including: (a) Filling, Restorative, and Prosthodontic Materials for Dentistry; (b) Dental Instruments and Equipment; and (c) Dental Vocabulary. The Standards within this Volume have been adopted without modification by the CSA Technical Committee on Dentistry (which is fully harmonized with the Canadian Advisory Committee to ISO Technical Committee on Dentistry) under the jurisdiction of the CSA Standards Steering Committee on Health Care Technology. The Standards have been approved as National Standards of Canada by the Standards Council of Canada March 1993 Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.
