ISO 11798 is a standard published by the International Organization for Standardization (ISO) that provides requirements and test methods for evaluating the permanence and durability of writing, printing and copying on paper. This standard is intended to assist those involved in the selection and use of paper for documents requiring long-term preservation.
ISO 11798 outlines several requirements for paper used for documents, including requirements for paper composition, pH and alkaline reserve. The standard also provides guidance on the use of paper additives and fillers, and the use of coatings and laminates for paper preservation.
The standard provides several test methods for evaluating the permanence and durability of paper, including accelerated aging, lightfastness and waterfastness tests. These tests are designed to simulate the effects of long-term exposure to environmental factors such as heat, light and humidity.
ISO 11798 also provides guidelines for the preparation and handling of test samples, including the size and shape of the sample and the test conditions. The standard also provides guidance on the selection of test equipment and procedures, including the type of equipment required for testing and the procedures for conducting the tests.
ISO 11798 also includes a section on the evaluation of test results, including guidance on how to interpret and report the various test results outlined in the standard. The standard emphasizes the importance of using statistical methods to analyze and compare data and provides guidance for the calculation and reporting of various parameters such as color change, fading and loss of strength.
The standard applies to a variety of applications, including selecting papers for archival and library collections, legal and financial documents, and other records requiring long-term preservation. It is also suitable for paper manufacturers, printers and other professionals involved in the production and handling of paper documents.
Overall, ISO 11798 provides a comprehensive set of guidelines and test methods for assessing the permanence and durability of paper and is an important resource for those involved in the preservation and archiving of printed materials. ISO 11798 is an important standard for those involved in the preservation of documents and other printed materials. By following the guidelines set forth in the standard, users can ensure that their paper documents are properly selected, processed and tested for long-term preservation.
