A proposal has been made for a new standard practice: "Accelerated Light Aging of Printing and Writing Paper by Xenon-Arc Exposure Apparatus."

The scope of the method is: This standard practice describes a laboratory procedure for the exposure of printing and writing paper to xenon-arc light at elevated levels of light flux to permit accelerated aging of that type of paper. This practice specifies the sample preparation and conditions of exposure required to obtain information on the relative stability of paper with regard to changes in optical properties brought about by exposure of such paper to light. This practice provides qualitative guidelines regarding paper stability and does not define the life expectancy for a given paper to reach a specified set of optical properties. The practice uses high-intensity broadband light sources that may not be suitable for the evaluation of light stability of paper that contain peroxide bleached mechanical pulps.

A Standard-Specific Interest Group (SSIG) must be formed for this proposal. Any individuals who are interested in this Standard may join the SSIG to receive ballots when this method is ready for vote. If you would like to join the SSIG for this project, please notify the Standards Department at standards@tappi.org or by fax at +1-770-446-6947 no later than September 27, 2010.
