<P>PROBLEM TO BE SOLVED: To provide a thermal history evaluation method for a molded product capable of making an accurate evaluation of a thermal load temperature or a thermal load time of the molded product influenced by thermal history as well as of facilitating a test with samples in small amounts. <P>SOLUTION: A thermal history evaluation of a molded product comprises the steps of: conducting a quantitative analysis of a predetermined index component for a molded product that is thermally pretreated with the predetermined index component; measuring the relationship between a thermal treatment time and an amount of the index component for a plurality of thermal treatment temperatures; forming a master curve indicating the relationship between the amount of the index component and the thermal treatment time with a prescribed thermal treatment temperature used as a reference temperature; collecting a sample from the molded product influenced by thermal history to conduct the quantitative analysis of the index component to measure the amount of the index component; calculating a reference thermal load time as a thermal load time converted into the reference temperature by using the amount of index component and the master curve. <P>COPYRIGHT: (C)2012,JPO&INPIT |
