Magnetic Media (T) - DIN Standard 66399

DIN 66399 is now referenced as ISO/IEC 21964

DIN 66399 Material Classification T refers to information on magnetic data carriers, for example ID-cards, data tapes, floppy disks, and diskettes. The Security Levels run from T-1 to T-7 with T-1 being recommended for data carriers with general data which have to made illegible, to T-7 for data carriers with top secret data where the strictest security standards must be maintained.

T1

  • Recommended, for example, for data carriers holding general data to be rendered illegible
  • Particle size: Mechanically inoperable
  • Shredded data can be reproduced without special knowledge or equipment, although the process is time-consuming

T2

  • Recommended, for example, for data carriers holding general data to be rendered illegible
  • Max. material particle size 2000 mm²
  • Shredded data can be reproduced with equipment, although the process is time-consuming

T3

  • Recommended, for example, for data carriers holding sensitive, confidential and personal data
  • Max. material particle size 320 mm²
  • Shredded data can only be reproduced with maximum effort and special equipment

T4

  • Recommended, for example, for data carriers holding particularly sensitive, confidential and personal data
  • Max. material particle size 160 mm²
  • Shredded data can only be reproduced utilizing equipment that is not readily available commercially

T5

  • Recommended, for example, for data carriers holding confidential information
  • Max. material particle size 30 mm²
  • Shredded data is unlikely to be reproduced even with special equipment

T6

  • Recommended, for example, for data carriers holding confidential information demanding an exceptionally high level of security
  • Max. material particle size 10 mm²
  • Shredded data cannot be reproduced even with special equipment

T7

  • Recommended, for example, for data carriers holding strictly confidential information demanding the highest security precautions (e.g. classified and top secret)
  • Max. material particle size 2.5 mm²
  • Shredded data cannot be reproduced in any way with the current state of science and art
