Abstract

This specification covers bond and ledger papers used in the preparation of permanent records and documents that are expected to have maximum, or substantial, life expectancy. Three types of bond and ledger papers are described, according to life expectancy level: type I - maximum life expectancy, type II - high life expectancy, and type III - medium life expectancy. These life expectancy levels are differentiated by pH and type of filler or sizing, or both. Fiber analysis, hydrogen ion concentration cold extraction, and filler shall be tested to meet the requirements prescribed. The grammage, thickness, internal tearing resistance, directional reflectance, opacity, and color shall be tested to meet the requirements prescribed.

Scope

1.1 This specification covers bond and ledger papers used in the preparation of records and documents that are expected to have maximum, or substantial, life expectancy.

1.2 It has been shown (, , , , ) that life expectancy is at least an approximate function of the pH of an aqueous extract of the paper. Three pH levels, reflecting three levels of life expectancy, are specified.

1.3 The following would be expected to contribute significantly to the life expectancy of books and documents: the use of papers with controlled acidity, or of papers manufactured under neutral or alkaline conditions, especially papers with a calcium carbonate filler that absorbs acidic gases from the atmosphere and can neutralize acidic materials formed in the aging of paper.

1.4 This specification is based on fiber sources used in the production of paper that contains no more than 1 % lignin, for papers used in archives, libraries, and other permanent records. However, under proper conditions, (see ), paper containing more than 1 % lignin may be employed for other end uses in paper for records that are required to have a substantial life expectancy.

1.5 As indicated in Appendix and , this specification may be used as a guide.
