The DIN 66399 classification system defines the maximum particle size of shredded material for a given security level. The higher the classification degree, the smaller the strips or particles of shredded material.

The classification level according to the Czech NSA (National Security Office) standard for shredders indicates the level of protection that the vault provides when shredding classified material. The NSA standards divide shredders into several security classes, from NNI 1 (Restricted) to NNI 4 (Top Secret), where each class corresponds to a specific classification level. These classes determine what types of documents can be safely disposed of in a given shredder, with NNI 4 representing the highest level of security for the most sensitive and classified documents. This classification is important for institutions and organizations that need to handle classified information in accordance with legal standards and security requirements.

This can also be referred to in the number of sheets and it's an indication of how much material can be shredded at the same time.
