Scope:

This non-destructive test may be used to measure the hydrogen ion concentration (pH) on the surface of the paper in books and documents that constitute the collections of libraries and government archives.

This method serves as an alternative to TAPPI T 509 "Hydrogen Ion Concentration (pH) of Paper Extracts - Cold Extraction Method," and TAPPI T 435 "Hydrogen Ion Concentration (pH) of Paper Extracts - Hot Extraction Method," because it avoids the destruction of printed material in the determination of the permanence expected for paper.

pH values obtained through the application of this method to sized materials such as writing, printing, and industrial papers reflect only the pH of the surface of these materials and should not be construed as pH values which may be determined by the cold water extraction method of the same material (1).
