ASTM D6789-02(2007)

Withdrawn Rationale:

This test method 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.

Formerly under the jurisdiction of Committee D06 on Paper and Paper Products, this test method was withdrawn without replacement in 2011. Based on discussions beginning over three years ago, plus an administrative ballot within D06 regarding the future of D06, it became clear that member support for maintaining the D06 Committee is lacking. Withdrawal of this standard continues a program of orderly withdrawal of the Committee D06 standards. In many cases, they exist as standards in other standards bodies. The technical equivalent of this standard is in publication as TAPPI T578 Accelerated Light Aging of Printing and Writing Paper by Xenon-Arc Exposure Apparatus.

1.1 This test method 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.

1.2 This test method specifies the sample preparation and conditions of exposure required to obtain information on the relative stability of paper with regard to change in optical properties brought about by exposure of such paper to light.

1.3 This test method provides qualitative results regarding paper stability and does not define the life expectancy for a given paper to reach a specified set of optical properties.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
