مقدمة

ايزو (المنظمة الدولية للمقاييس) هو تحالف عالمي لهيئات المعايير الوطنية (الهيئات الأعضاء في منظمة الأيزو). عادة ما يتم تطوير المعايير الدولية من خلال اللجان الفنية ISO. يحق لكل مؤسسة عضو مهتمة بموضوع تم تشكيل لجنة فنية له أن تكون ممثلة في تلك اللجنة. وتشارك أيضًا في هذا العمل المنظمات الحكومية الدولية وغير الحكومية المتعاونة مع ISO. تعمل ISO بشكل وثيق مع اللجنة الكهروتقنية الدولية (اللجنة الانتخابية المستقلة) في جميع المسائل المتعلقة بالتوحيد القياسي الكهروتقني.

وسيتم توزيع مشروع المعايير الدولية الذي اعتمدته اللجنة الفنية على الهيئات الأعضاء للتصويت عليه. النشر كمعيار دولي يتطلب موافقة على الأقل 75% of member bodies.

المعيار الدولي ISO 11798 تم تطويره من قبل اللجنة الفنية ISO/TC 46, المعلومات والتوثيق, اللجنة الفرعية SC 10, Physical Preservation of Documents.

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

يقدم
Writing materials and devices that meet the requirements of this international standard may be used to prepare paper documents with stable and durable images, أي. 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, الطباعة, 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 (ايزو 9706) and archival files (ايزو 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.

في هذا المعيار, the requirements are based on

— image color intensity and appearance;

— light resistance;

– ضد للماء;

– transmission of recorded images;

— ارتداء المقاومة;

— مقاوم للحرارة;

– 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. لكن, 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. لذلك, 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. في التمرين, 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 يتراوح
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” يتراوح;

— 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, إشعاع (such as light), high concentrations of contaminants, or water that may promote microbial attack. لكن, 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.
