DIN PNG wide

DIN 66399 is now referenced as ISO/IEC 21964

DIN 66399 Material Classification E refers to information on electronic data carriers, for example chip cards and memory sticks. The Security Levels run from E-1 to E-7 with E-1 being recommended for data carriers with general data, which have to made illegible to E-7 for data carriers with top secret data where the strictest security standards shall be maintained.

E1

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

E2

  • Recommended, for example, for data carriers holding general data to be rendered illegible
  • Particle size: Split
  • Shredded data can be reproduced with equipment, although the process is time-consuming

E3

  • 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 with maximum effort and special equipment

E4

  • Recommended, for example, for data carriers holding particularly sensitive, confidential and personal data
  • Max. material particle size 30 mm²
  • Shredded data can only be reproduced utilizing equipment that is not readily available commercially

E5

  • Recommended, for example, for data carriers holding confidential information
  • Max. material particle size 10 mm²
  • Shredded data is unlikely to be reproduced even with special equipment

E6

  • Recommended, for example, for data carriers holding confidential information demanding an exceptionally high level of security
  • Max. material particle size 1 mm²
  • Shredded data cannot be reproduced even with special equipment

E7

  • 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 0.5 mm²
  • Shredded data cannot be reproduced in any way with the current state of science and art
