The IOSA Standards Manual (ISM) is published in order to provide the IOSA standards, recommended practices (ISARPs), associated guidance material and other supporting information necessary for an operator to successfully prepare for an audit.
The ISM may also be used as a guide for any operator desiring to structure its operational management and control systems in conformity with the latest industry operational practices.
The ISM is the sole source of assessment criteria to be utilized by auditors when conducting an audit
against the ISARPs.
