Introduction

Librarians and archivists found. libraries and archives in typical storage conditions of 50 years ago has begun to paper documents Significant deterioration phenomenon. Over the past 1,500 years of history shows that high purity fibers in paper copy made with a very high durability.

The results of modern science and technology research has also demonstrated that the main reason for deterioration of paper containing fiber degradation promoting compounds in the raw materials and ingredients in papermaking Substance, such as rosin, alum and other acidic substances.

This standard aims to provide identification and validation method has high durability of the paper. The so-called high-durability paper refers In one subject Protection of the environment and long-term storage, which will affect its stability and performance indicators be little or no change in the paper.

ISO 11799 "Information and Documentation Books and literature archives storage requirements," has information and documentation technology standardization by the International Organization for Standardization Surgery Commission to develop and publish.

This standard is based on a quantitative test, for each test are given limited value.
