International Standard ISO 3672-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 12, Thermosetting materials. This second edition cancels and replaces the first edition (IsO 3672:1979), which has been technically revised. Part1:Designationsystem Part2:Preparation of test specimens and determination ofproperties @ ISO 2000 - All rights reserved INTERNATIONAL STANDARD ISO3672-1:2000(E) Plastics Unsaturated-polyester resins (UP-R) - Part 1: Designation system 1 Scope 1.1 This part of isO 3672 establishes a data block system for the designation of unsaturated-polyester resins (UP-R). 1.2The various types of UP-R are differentiated from each other by a classification system based on information about the basic polymer parameters, the possible fillers/reinforcements (type and content), the intended method of purposes (designatory properties). 1.3This part of IsO 3672 is applicable to all types of unsaturated-polyester resin for normal use in a liquid state and in a solid state. 1.4 It is not intended to imply that materials having the same designation necessarily give the same such additional properties are required, they shall be determined in accordance with the test methods specified in part 2 of this International Standard, if suitable. 1.5To ensure that code-letters and code-numbers remain unambiguous and to avoid conflicts within the system, any new code-letters or code-numbers for use in data block 1, 2 or 3 shall be approved before use by the secretariats of ISO/TC 61/SC 1, SC 12 and SC 13. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of thispartofisO3672.Fordatedreferences,subsequentamendmentsto,orrevisionsof,anyofthesepublications donotapply.However.partiestoagreementsbasedonthispartofisO3672
