AAT ICAS 3130 ✧ mainChron term set

document note: this document is part of the Integrated Chronological Applications System (ICAS). Alliance for the Advancement of Technology (AAT) provides ICAS standards documents subject to terms of use described in document AAT ICAS 9010. please refer to other key AAT ICAS standards documents accessible via the AAT ICAS web site at https://www.aatideas.org/icas for important information about ICAS.

this document designates the AAT ICAS mainChron term set. AAT ICAS Inter-Dial Clock (IDC) chron-unit derived terms and notation are appropriate for fixed implementations of IDC main unit. special note: IDC prefixes are derived from two schemes each possessing certain schematic usage conventions: metric prefixes (SI prefixes) and the derived clock unit prefixes (tiko and toko). please see AAT ICAS 2023 for additional information.
