Many Print File products say they have passed the PAT. What is the PAT?
The Photographic Activity Test (PAT) is a worldwide standard (ISO Standard 14523) for archival quality in photographic enclosures. Developed by Image Permanence Institute in Rochester NY, this test predicts possible interactions between photographic images and the enclosures in which they are stored. The PAT is also used to test the components of enclosures, such as adhesives, inks, paints, labels, and tapes. The test involves incubating materials in temperature- and humidity-controlled chambers to simulate aging and takes from four to six weeks. After incubation and sample evaluation, a final report is provided.
