適用范圍：1 This part of ISO 3672 establishes a data block system for the designation of unsaturated-polyester resins (UP-R). 2 The 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 processing, any specified properties and those of the specified properties used specifically for designation purposes (designatory properties). 3 This 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. 4 It is not intended to imply that materials having the same designation necessarily give the same performance. This part of ISO 3672 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. If 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. 5 To 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.
