Zusammenfassung:An environmental exposure indicator includes a substrate and an environmental exposure indicator ("EEI") material provided on the substrate that is configured to change an optical property between a creation state and an end state. The environmental exposure indicator material has a deployment state, between the creation state and the end state, at a deployment time. The environmental exposure indicator also includes calibration data based on the deployment state.
