1、Designation:D 3208 00Standard Specification forManifold Papers for Permanent Records1This standard is issued under the fixed designation D 3208;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in par
2、entheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers manifold papers used in pre-paring typewritten copies of permanent or semipermanentrecords and documents.The original,or ribb
3、on,copy usuallyleaves the organization in which it originated,so the carboncopy becomes the copy of record.1.2 It has been shown(1,2,3,4,5)2that permanence is atleast an approximate function of the pH of an aqueous extractof the paper with correlation coefficients ranging from approxi-mately 0.7 to
4、0.9(4).Three pH levels,reflecting three levels ofpermanence,are specified.Extract pH as an indicator of lifeexpectancy is not valid if a paper has been treated with analkaline surface size or if an alkaline coating has been applied.1.3 The following would be expected to contribute signifi-cantly to
5、the life expectancy of manifold papers:the use ofpapers with controlled acidity,or of papers manufactured underneutral or alkaline conditions,especially papers with a calciumcarbonate filler that absorbs acidic gases from the atmosphereand can neutralize acidic materials formed in the aging ofpaper.
6、1.4 This specification is based on fiber sources used in theproduction of paper that contains no more than 1%lignin,forpapers used in archives,libraries,and other permanent records.However,under proper conditions,(see X1.5),paper contain-ing more than 1%lignin may be employed for many other enduses
