Paper Shredder Security Levels DIN 66399

Which security level do you need for paper shredding?

When you are looking for a new shredder you often see the security level of a paper shredder. For instance P2, P3 or P4. What does the security level mean and why is it important to pay attention on it when you are buying a new shredder machine? On this page we explain the shredder security levels.

The size of the particle

The security levels for paper shredders are part of the official DIN 66399 standard for paper destruction. This standard contains seven security levels which indicates the minimal requirements for the size of the paper particles after shredding a document. These seven levels are DIN P-1, P-2, P-3, P-4, P-5, P-6 and P-7. The higher the number the smaller the size of the particle gets.

For instance when you are looking for high security and want small particles, then you are better of with a P-5 paper shredder than a P-2 paper shredder. That is because the paper particles from a P-5 micro-cut shredder are very small in comparison with the strips of a P-2 strip-cut shredder.

Besides security levels you can also find the cut type of paper shredders. All paper shredders can be devided in three types of paper cuts. These are strip-cut, cross-cut and micro-cut. Below you can see all the security levels from the German DIN 66399 standard for paper destruction:

1. Strip-cut – Low level of security
2. Cross-cut – Medium level of security
3. Micro-cut – High level of security
