arkivkvalitetsmaterial

Arkivkvalitetsmaterial refers to materials selected for long-term preservation of archival records and museum objects. The term is used by libraries, archives, and cultural heritage institutions to describe substances designed to minimize chemical and physical deterioration of stored items and to avoid introducing contaminants.

Key properties include stability, low acidity, and non-detrimental composition. In practice, arkivkvalitetsmaterial are pH-neutral or buffered to an alkaline level, contain little to no lignin, chlorine, or sulfur compounds, and use inks, pigments, and adhesives that do not off-gas or react with stored materials. Papers are often described as permanent or archival and meet standards such as ISO 9706. Enclosures such as jackets, folders, and boxes are made from acid-free, lignin-free papers or from stable plastics like polyester (PET) or polypropylene.

In addition to paper and enclosures, archival-quality materials extend to magnetic and optical media, where archival tapes and protective sleeves are used, as well as mounting media and adhesives that are non-reactive.

Standards and certification: Many institutions follow general guidelines set by international standards and professional organizations; ISO 9706 is widely cited for paper permanence, and other standards cover plastics, adhesives, and packaging. Archives often maintain material specifications and supplier audits.

Usage and limitations: Even with arkivkvalitetsmaterial, long-term preservation requires controlled storage conditions, regular monitoring, and avoidance of harmful environments; replacement and re-housing may be necessary.
