Paper testing of archival and permanent paper
Our paper testing is mainly focused on paper used for documents. Permanent paper is often used for copying. Archival paper is made from textiles and is much stronger and therefore more suitable for documents that should be stored, e.g. ratings and diploma. Paper that has been tested and certified by RISE can be marked with “Svenskt arkiv”.
Purpose
Permanent documents are those that may be stored for several hundred years in protected environments. Either permanent paper or archival paper is recommended.
Archival paper shall meet the requirements for permanent paper. The archival papers are stronger than the permanent paper and can withstand considerably more handling.
Method
Archival paper is evaluated according to ISO 11108 and permanent paper according to ISO 9706. The regulations of the Swedish National Archive refer to these standards.
Permanent paper (ISO 9706)
- shall have a pH-value between 7,5 and 10,0
- shall have an alkali reserve at least corresponding to 0,4 mol acid per kg paper (at least 2% calcium carbonate)
- shall have tearing resistance of at least 350 mN in the machine- and cross direction
- shall have a Kappa number less than 5, which means that the paper may contain only a small amount of easily oxidized material (e.g. lignin)
Archival paper (ISO 11108)
- shall meet the requirements of permanent paper (ISO 9706)
- shall be made from cotton, cotton linters, hemp or flax, but may contain a minor fraction of fully bleached chemical pulp
- shall have a folding endurance of at least 2,18 (more than 150 foldings)
The archival papers are stronger than the permanent paper and can withstand considerably more handling.
Deliveries
A test report, and a certificate if the product is approved, which can be used as a guarantee for archival durability and permanence
