This part of DIN EN ISO 3673 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of crosslinked epoxy resins. The properties to be determined have been selected from the general test methods in ISO 10350-1:2007. In order to obtain reproducible and comparable test results, it is necessary to use the test methods, sample preparation and conditioning, and specimen dimensions specified herein. Values determined will not necessarily be identical to those obtained using test specimens of different dimensions or prepared using different procedures. ISO 3673-2:2012 has been prepared by ISO/TC 61/SC 12/WG 5 "Unsaturated polyesters, epoxy resins and other resins" (secretariat: JISC, Japan). The committee responsible for the European Standard is CEN/TC 249 "Plastics", the secretariat of which is held by NBN (Belgium). The committee responsible for the standard on the national level is Working Committee NA 054-02-01 AA "Härtbare Harze" ("Thermosetting materials") of FNK at DIN.
