| Resumen: | This British Standard specifies requirements for leather to be used in archival bookbinding, for which purpose the following leathers are suitable:
Leathers tanned solely with vegetable tannins, or chrome re-tan leather in which the chrome tanned leather has been further tanned solely with vegetable tanning agents, are not suitable and are thereby excluded. In addition, although alum tawed bindings have been proved to have long term durability, alum tawing cannot be regarded as a true tannage and therefore such leather is not included in this specification.
