The purpose of ISO/IEC 24789 is to provide guidance on methods and their use to simulate a card's service life. In order to achieve this purpose, two parameters of card service life are defined: age and usage. This can be represented as a two‑dimensional matrix in which each age/usage combination corresponds to a card service life class. The two parts of ISO/IEC 24789 together describe the evaluation methods to be used and their criteria.
ISO/IEC 24789 was originally developed for ID-1 cards conforming to ISO/IEC 7810, but might be found useful in whole or in part for other types and form factors.
References are given to the corresponding methods of evaluation in ISO/IEC 24789-2 and elsewhere.
