"Alkaline reserve" means the presence of a compound (e.g. calcium carbonate) put in paper at a level sufficient to neutralize acid that might, in the future, be generated from aging of the paper or from atmospheric pollution.
"Groundwood" means pulp produced by mechanically defibering wood without chemical cooking; such pulp contains many substances deleterious to the permanence of paper.
"pH" means the negative logarithm of the hydrogen ion activity in an aqueous solution or the logarithm of the reciprocal of the hydrogen ion activity. Numerically expressed, pH 7 is neutral, lower numbers are acidic. Higher numbers are alkaline. The concentration of the free hydrogen ions is expressed as an exponent, so the pH 4 is 10 times more acidic than pH 5 and 100 times more acidic than pH 6.
"Permanence," for the purpose of this standard when referring to paper, means paper that will last at least several hundred years without significant deterioration under normal use and storage conditions.
"Uncoated," for the purpose of this standard when referring to paper, means paper that is composed of fiber plus fillers, sizing, dyes, etc., but with no surface coating in excess of 2.5 pounds per side for every 500 sheets measuring 25 inches by 38 inches.
