Dear all,
I am looking for guidance on the recommended temperature and humidity for the long-term storage of magnetic tape.
We have till now referred to BS 4783 Storage, Transportation and Maintenance of Media for Use in Data Processing and Information Storage - Part 4 Recommendations for Magnetic Tape Cartridges and Cassettes, and have therefore regarded 18-22 degrees celcius and 35-45%RH as what is required. However this standard has now been withdrawn by BSI as it is now "no longer relevant". Does anyone know if anything has replaced it?
Also, there is another standard, ISO 8923: 2000 – Imaging Materials – Polyester-base Magnetic tape – Storage practices, last reviewed 2012. The specification is quite different, recommending between 11 and 23 degrees celcius and RH of between 20 and 50% (maximum 11 degrees with a RH of 50%, or 17 degrees with a RH of 30% or 23 degrees with a maximum of 20%).
I would be very grateful for any advice anyone can give on this.
Many thanks.
Regards,
Emily Burningham
