1、Designation:D5634 01(Reapproved 2006)An American National StandardStandard Guide forSelection of Permanent and Durable Offset and BookPapers1This standard is issued under the fixed designation D5634;the number immediately following the designation indicates the year oforiginal adoption or,in the cas
2、e of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide covers offset and book papers,both coatedand uncoated,used in the preparation of perma
3、nent records.Permanent records usually are expected to last several hundredyears in a records repository,with little change in propertiesthat affect readibility or handling,although some records areexpected to have shorter lifetimes.1.2 Acidic materials incorporated in paper during manufac-ture(for
4、example,rosin-alum sizing)contribute to deteriora-tion.It has been shown(1,2,3,4,5)2that the life expectancyof uncoated papers is an approximate function of the pH of anaqueous extract of the paper.1.3 The following would be expected to contribute signifi-cantly to the life expectancy of books and d
5、ocuments:the useof papers with controlled acidity or of papers manufacturedunder neutral or alkaline conditions,especially papers with acalcium carbonate filler that absorbs acidic gases from theatmosphere or can neutralize acidic materials formed in theaging of paper.1.4 Three pH levels reflecting
6、three levels of life expectancyare outlined in this guide.As one cannot rely on pH alone as anindicator of stability,minimum retentions of properties afteraccelerated aging at 90C and 50%relative humidity aresuggested for the three levels of life expectancy.1.5 In selecting papers for permanent reco
7、rds,papers withacceptable durability are evaluated for life expectancy throughaccelerated aging.1.6 This guide should be used in the purchase of paper forpermanent records.1.7 This guide is based on the use of fiber sources used inthe production of paper that contains no more than 1%ligninfor papers
8、 used in archives,libraries,and other permanentrecords.However,under proper conditions(see X1.8)papercontaining more than 1%lignin may be employed for manyother end uses in paper for records that are required to have asubstantial life expectancy.1.8 This standard does not purport to address all of t
9、hesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:3D585 Practice for Sampling and
