ISO 19005-1 defines a file format based on PDF, known as PDF/A, which provides a mechanism for representing electronic documents in a manner that preserves their visual appearance over time, independent of the tools and systems used for creating, storing or rendering the files. (from ISO 19005-1). The Standard does not define an archiving strategy or the goals of an archiving system. It identifies a profile for electronic documents that ensures the documents can be reproduced in years to come.
This test suite comprises a set of files which can be used to check the conformance of software regarding the PDF/A-1 standard. More precisely, the Isartor test suite can be used to validate the validators: It deliberately violates the requirements of PDF/A-1 in a systematic way in order to check whether PDF/A-1 validation software actually finds the violations.
The Isartor test suite is available from www.pdfa.org free of charge. It can be used to check PDF validation software and software vendors can use it to “certify” that their products conform in full or in part to the Isartor test suite. A detailed list of test results must be made available as part of the declaration.
