The Photographic Activity Test
The Photographic Activity Test, or PAT, is a worldwide standard (ISO Standard 18916) for archival quality in photographic enclosures. Developed by IPI, this test predicts possible interactions between photographic images and the enclosures in which they are stored.

pH and Alkaline Reserve Tests
IPI tests photo storage products for pH levels using the standardized test, TAPPI T 509 Hydrogen Ion Concentration (pH) of paper extracts (cold extraction method). This determines if a material is acidic, basic, or neutral with respect to pH. The test involves soaking a sample in distilled water and then comparing the sample’s pH to the initial pH of the water.
IPI tests for alkaline reserve of paper by soaking a sample in water, in a manner similar to that for the pH test, and then measuring the amount of acid necessary to neutralize the alkaline buffering. This test determines the percent alkaline reserve of the paper. Alkaline reserves are added to paper and paperboards to neutralize acids that are created or absorbed as the paper deteriorates over time.
For questions on the amount of sample required for testing please call IPI at 585-475-5931. Materials should be shipped to:

It should be noted that pH and alkaline reserve testing are destructive tests; sample materials cannot be returned. We ask that you name or code your samples so that we have a reference by which to communicate the test results. This is important; our test reports will refer only to your specific label. All test results are confidential. You alone will receive a copy of the reports. You may, if you wish, make the information in the reports available to the public. Some of our customers do this.
Price list for tests and servicesLight-Stability Testing
IPI determines the effects of light on photos, ink jet prints, and other imaging media by exposing samples to high-intensity xenon arc or fluorescent illumination. IPI's light-fading lab is equipped with a 50-kilolux Weatherometer, a 50-kilolux fluorescent unit, and a 10-kilolux fluorescent unit. IPI can custom-design light-stability studies for specific needs.
IPI has done light-stability testing for Eastman Kodak Company; Hewlett-Packard; Ilford USA; E. I. duPont deNemours and Company; Fuji Photo Film, Ltd.; Agfa Division, Bayer Corporation; 3M Company; and Konica Corporation, among others.

Pollution Testing
The contribution of air pollution to the fading of images is not easy to measure or observe in the storage environment; its effects are subtle and occur slowly, combining with the effects of age, light, heat, and humidity. It is impossible to say , for example, what percentage of the fading of a color print is due to air pollution.
IPI is equipped to test materials commonly used in still photography, cinema, microforms, and computer color hard copies for the optical, chemical, and physical changes that occur when they are exposed to gaseous pollutants at different concentrations, temperatures, and humidities. Enclosure materials can be tested as well. IPI's pollution lab houses two custom-built, 21-cubic-foot chambers for studying the effects of such air pollutants as sulfur dioxide, nitrogen dioxide, hydrogen sulfide, and ozone. For more information about pollution testing, please contact us at ipiwww@rit.edu.

IPI has extensive experience in designing accelerated-aging tests in order to observe the effects of heat and humidity on the stability of organic materials. Temperature and humidity are the two most influential factors involved in the decay of organic materials. Testing is done by setting and maintaining controlled conditions and exposing sample materials for specific periods of time. For more information about accelerated-aging testing, please contact us at ipiwww@rit.edu.
Price list for tests and servicesPhysical Testing
Materials commonly found in collections include those used as image supports as well as those used in the construction of archival enclosures. Because they are physically diverse and are used in many different ways, a variety of tests is required to determine their physical properties. Often, after accelerated aging, a material is put through a series of tests to measure any degradation of its physical integrity. IPI has facilities for testing typical collection media for abrasion and tear resistance, blocking, fold endurance, and optical properties. For more information about physical testing, please contact us at ipiwww@rit.edu.
