Photographic Activity Test - PAT Tested

Photographic Activity Test (PAT)
The Photographic Activity Test, or PAT, is an international standard test (ISO18916) for evaluating photo-storage and display products. Developed by IPI, this test explores interactions between photographic images and the enclosures in which they are stored. The PAT is routinely used to test papers, adhesives, inks, glass and framing components, sleeving materials, labels, photo albums, scrapbooking supplies and embellishments, as well as other materials upon request.  This test can be performed on products in development as well as on materials already in use in collections. 

We encourage producers of photo-storage and display products to purchase and review ISO 18916 describing the Photographic Activity Test. After reviewing the standard, contact us with any questions that may arise. ISO 18916 can be purchased at
