International standard: DIN66399

Miaoyi complies with DIN 66399 standard for data destruction, and can customize services according to customer needs

DIN is the standardization authority in Germany, and DIN 66399 is the new standard for the German data destruction industry and the leading international standard.

The storage media containing our confidential data and information are varied. Along with paper, the classic data medium, digital data media now also plays a major role. The DIN 66399 standard takes this diversity into account, and defines what security means for all our modern media. The DIN 66399 supersedes DIN 32757 and describes the requirements for machines and processes for shredding data media. The standard was developed by the Standards Committee for Information Technology and Applications (NIA).
