A new ISO standard describing test methods for photo books issued on November 13, 2018. While this standard, ISO 18948:2018, stops short of providing a specification for long-term permanence, it does provide specific test methods that manufacturers can use to evaluate photo books.
- Page pull test
- Peeling and lamination durability
- Book block attachment to the cover
- Page stability, including storage and vehicle transportation
- Deformation caused by humidity
Photo book manufacturers have resisted the development of standards giving requirements for photo books intended for long-term preservation; consequently the best information that is available comes from the publishing industry with ISO 11800:1998. This standard provides specific requirements for manufacturing durable and long-lasting books. Much of the information is also relevant to photo books.
