19、 DOCUMENTS PREFACE This standard was developed by the Canadian General Standards Board Subcommittee on Permanence of Paper. This Subcommittee was established in November 1991 and was harmonized with the Canadian Advisory Committee on ISOC 46/SC 10 Physical Keeping of Documents for the review and dev

20、elopment of standards relating to the permanence of paper and was approved by the CGSB Committee on Printing and Writing Paper. As in other nations, Canadian librarians, archivists and conservators have long observed the rapid deterioration which threatens much of our paper-based heritage. While sto

21、rage conditions and environmental factors contribute to this deterioration, scientists also recognized that some of the components and chemical processes used in the manufacture of paper play a large role in its decomposition. Deacidification, microfilm and digital technology can help forestall the

22、loss of deteriorating materials but are costly solutions for libraries and archives. The simple preventative strategy of printing records and publications on permanent paper can help ensure that our heritage is still usable hundreds of years from today. In drafting this standard, the Committee began

23、 with the definition of paper permanence found in the ANSI and IS0 standards: the ability of paper to last at least several hundred years without significant deterioration under normal use and storage conditions in libraries and archives. The Committee recognized that two aspects of permanence are i

24、nvolved: mechanical permanence or the maximum retention of the papers strength properties; and opricaf permanence, which is not scientifically defined but is generally assumed to mean the maximum retention of the papers original brightness and colour. Librarians and archivists are concerned about th

25、ose parameters of permanence which affect the long-term usability of paper and the legibility of the information it contains. While mechanical permanence is essential in all cases, the need for optical permanence is variable. For many applications, a degree of change in appearance can be tolerated p

26、rovided it does not have a negative impact on the legibility or reproducibility of the information. For some documents with high aesthetic or artifactual value, any degree of visible change is undesirable. While permanent paper standards exist in other countries, the debate in Canada centred on the

27、limitation on lignin-content common to these standards. This resulted in Canadas decision to submit an abstaining vote on the Draft International Standard DIS 9706. Both the ANSINSO Z39.48:1992 and IS0 9706:1994 standards contain references to the fact that some alkaline papers with levels of lignin

28、 higher than those specified in their standard passed the accelerated aging tests used in their standard development process. However, alkaline papers containing more than 1 % lignin were subsequently excluded due to the expressed need for further research to define more precisely the conditions und

29、er which higher levels of lignin are compatible with paper permanence. IS0 also indicated concern over the lack of scientific certitude around the effects of oxides of sulphur and nitrogen in the atmosphere on lignin-containing fibres. Addressing the need to learn more about the impact of lignin on

30、paper permanence before work could begin on a Canadian standard, the CGSB Subcommittee on Permanence of Paper developed a research program for which Government and industry sponsorship was obtained. The requirements in this standard are based upon the results of this Canadian Co- operative Permanent

31、 Paper Research Project, which concluded its three-year examination of the impact of lignin on paper permanence in April 1997. This research which confirmed earlier work on mechanical properties, found that an alkaline reserve is very effective in reducing the negative impact of airborne pollutants

32、and accelerated aging on both lignin- containing and lignin-free sheets?. The key finding of this project was that in alkaline papers buffered with calcium carbonate (those with a pH of 7.0 or higher), the presence of lignin has no negative impact on their mechanical permanence. An adequate alkaline

33、 buffer is, therefore, the main determinant of mechanical permanence of paper. The CGSB standard Zou. X Gumagul, N., Deschtelets, S., Bgin, P., Iraci. J Grattan. D., Kaminska.

This standard recognizes that there are no specifications and thus no optical permanence assuranc

36、es offered in any of the permanent paper standards published at the time of this writing. Because there is an absence of usable science on which to base specifications, in order to give a greater level of assurance to paper buyers and users, the Committee concluded that the CGSB standard would offer

37、 guidance that will potentially provide for a high level of optical permanence based on accumulated practical experience. (See Appendix B .) As a result of these discussions, two categories of permanence have been established: I) mechanical and 2) mechanical and optical. ii Copyright Canadian Genera

39、NENCE OF PAPER FOR RECORDS, BOOKS AND OTHER DOCUMENTS PURPOSE AND SCOPE The purpose of this standard is to define permanence requirements for papers in a broad range of coated and uncoated paper grades. When used in conjunction with other CGSB paper standards specifying each grades performance and p

40、hysical requirements, this standard defines additional requirements necessary to provide a high degree of certainty that a paper will remain usable for several hundred years without significant deterioration, under normal use and storage conditions in libraries and archives. A key objective of the s

41、tandard is to ensure that paper buyers and specifiers have clear information on the permanence of any paper product meeting the requirements of this standard. The standard applies to a broad range of paper grades commonly used in the production of records, books and other documents, which could be r

42、etained by archives and libraries, such as: CANICGSB-9.1, CANKGSB-9.28, CANCGSB-9.66, and CAN/CGSB-9.67, or any other paper standards. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purpo

43、rt to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any existing applicable regulatory requirements prior to its use.
