предговор

ИСО (Међународна организација за стандардизацију) је глобални савез националних тела за стандардизацију (Тела чланица ИСО). Развој међународних стандарда се обично спроводи преко ИСО техничких комитета. Свака институција чланица заинтересована за предмет за који је основан технички комитет има право да буде заступљена у тој комисији. Међународне владине и невладине организације које су у вези са ИСО такође су укључене у овај посао. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електротехничке стандардизације.

The draft international standards adopted by the Technical Committee will be circulated to member bodies for voting. Објављивање као међународни стандард захтева одобрење најмање од стране 75% of member bodies.

International standard ISO 11798 је развијен од стране Техничког комитета ИСО/ТЦ 46, Information and Documentation, Subcommittee SC 10, Physical Preservation of Documents.

Annexes A and B form an integral part of this international standard. Annex C is for reference only.

ИСО 11798-1999 Information and Documentation – Persistence and durability of writing, printing and copying on paper – Requirements and test methods

увести
Writing materials and devices that meet the requirements of this international standard may be used to prepare paper documents with stable and durable images, тј. images that may have little or no variation in characteristics affecting readability, and the possibility of copying or converting paper documents into other data carriers, such as microforms.

It is primarily used for writing, штампање, and copying on writing and printing paper as well as copying paper.

This standard specifies the requirements and test methods for assessing image stability. Certain properties of the image, such as wear resistance, depend on the combination of the image and the paper. Permanent files (ИСО 9706) and archival files (ИСО 11108) used to prepare files can differ greatly in attributes that are important for image quality and persistence. The test conditions of this standard are selected in order to obtain results representative of the majority of papers on the market for a particular imaging process.

In this standard, the requirements are based on

— image color intensity and appearance;

— light resistance;

– водоотпоран;

– transmission of recorded images;

— отпорност на хабање;

— heat resistance;

– Record the influence on the mechanical strength of the paper.

More stringent limits and other requirements than those set out in this international standard may be required when testing materials and machinery for documents of the highest durability and durability.

Experience has shown that images written with India ink, as well as printed images using commercial printing inks, are highly durable. Међутим, in many documents, acid inks have affected the paper to the point of paper corrosion, and images produced by dry or liquid toner are also susceptible to aging problems.

The experience of modern images is limited to a few decades. Images prepared with modern materials and machinery are often completely different from older images in terms of composition and properties. Стога, conclusions based on studies of older documents in libraries and archives are of limited use when discussing the persistence of modern documents.

Strictly speaking, the only way to test the persistence of an image is to process the document and store it under relevant conditions for a long time, perhaps hundreds of years. In practice, one must rely on observations of documents that are only a few years old, and an assessment of the impact of factors known to affect the persistence and persistence of images.

1 домет
This standard sets out requirements and test methods for assessing the persistence and durability of writing, printing and copying on paper stored for long periods in libraries, archives and other protected environments.

It is applicable to

— Images on paper, except for documents within the ISO/TC 42 “photography” домет;

— Colorful images.

The information content of a color image should be preserved, but not necessarily the full artistic quality of the color image. Files whose information content is subject to minor colour changes are not covered by this standard.

It doesn’t apply to

– Documents stored under harmful conditions, such as the effects of high humidity, overheating, radiation (such as light), high concentrations of contaminants, or water that may promote microbial attack. Међутим, because files may be kept in an unprotected environment before being transferred to a protected environment, water and light resistance are important;

– Legal documents, such as bank documents, where authenticity is a major concern.
