What Is A Level 6 Shredder?

Such a shredder is a high-security device with a level 6 rating, the highest level of security. They cannot handle high-volume shredding as they are slow. They meet the NSA/CSS Specification 02-01 requirements and are thus NSA/CSS approved. NSA stands for National Security Agency and CSS stands for Central Security Service.

How Small Are The Shredded Particles?

The particles have to be equal to, or smaller than, 1 mm x 5 mm (or 1/32” x 5/32”), according to NSA requirements for destruction. However, some models are made with a different cut pattern shredding paper into particles with an area equal to 1/26” x 1/5” which is also acceptable for level 6 and is NSA/CSS approved.

Government Level 6 Vs. DIN 66399 Guidelines

DIN 66399 laid out the details for seven different levels of security. Level 6 is just below Level 7 which is the highest security level for a shredder. DIN Level 6 is also called P-6 Shredder while level 6 of government security corresponds with P-7 DIN level. Alternatively, some paper shredders are approved by the DoD (Department of Defense).

What Are The Different Security Levels & Sizes For Shreddings?

According to DIN 66399, there are seven security levels.
Level P-1 is not recommended for confidential documents as it cuts paper only into strips that are under 12 millimeters wide.
Level P-2 is still not recommended for sensitive documents as it shreds paper into strips that are only under 6 millimeters wide.
Level P-3 offers high speed and shreds paper so that it is under 2 millimeters wide so it is the best option for fast shredding while providing enough security.
Level P-4 is a cross-cut where particles are under 6 millimeters wide and have an area of under 160 millimeters squared, providing more security.
Level P-5 is a cross-cut where particles are under 2 millimeters wide with an area of up to 30 millimeters squared.
Level P-6 is a cross-cut where particles are under 1 millimeter wide and the area of one particle is under 10 millimeters squared.
Level P-7 is the highest security level where particles are under 1 millimeter wide and the area of one particle is under 5 millimeters squared. The P-7 DIN level corresponds with government level 6 for a paper shredder.

What Are They Used For?

These shredders are high-security micro-cuts, great for destroying sensitive information and confidential documents. They can destroy business paperwork, credit cards, junk mail, personal mail and documents, bank statements, receipts, and more.

How Do You Know If You Need One?

If you are looking to solve one of the following problems, then this machine is the right choice for you:

  • Getting rid of top-secret documents – this is especially helpful in government offices where top-secret data is being dealt with
  • You want maximum security – with really particles, it will be impossible for anyone to steal your identity or look through your sensitive data
  • You don’t need to shred too much at once – this is because such a high-security paper shredder cannot cut fast or a lot at once to be able to produce really tiny shreds

What To Consider When Buying One?

Level 6 security offer is filled with different sizes, shredding volumes, safety features, speed limitations, and motor power.

Shredding Speed

The micro-cut paper shredder usually runs slower than the other two types because they shred slowly, but efficiently. The paper shredder with a more powerful motor runs a bit faster, so check out the motor power.

Motor Power (HP)

Shredders for highly confidential documents need powerful motors to be able to shred paper efficiently into such tiny cuts. On the market, some have a motor power range of between 2.4 and 4.8 Horse Power.

P-6 paper shredder power

Paper Size

Some machines can shred A4-sized paper and some can even handle larger sizes. Pick the model that can handle the maximum width of the paper you want to shred.

Safety Needs

Automatic reverse and automatic shut-off are safety features that are good to have. This will help with paper jams as you won’t have to expose your fingers to the blades if the paper gets stuck inside.

paper shredder p-6 features

Shred Volume & Speed

Depending on the power of the motor, they can handle between 3 and even 13 sheets per pass. The bigger the shred volume, the bigger the speed, as well. Pick a model with a higher volume if you need to get rid of more documents quickly. Otherwise, even a 5-sheet shredder will suffice.

Noise Level For A Distraction-Free Workplace

If your shredder will be close to employees in the office, the noise level might be a distraction for them. This is why you might need a quieter option.

What Else Should You Keep In Mind?

Will These Machies Cut Through Other Media?

These machines shred paper into really tiny particles and they are mostly not intended for destroying types of media (CDs, DVDs, ID cards). However, do check with your machine’s manual to make sure it is the case with the device you chose.

Levels Of Classified Papers

In the US, the three main levels of classification for information are confidential, secret, and top-secret, from least to greatest level respectively. These are defined in EO 12356. With these shredders, you can destroy even top secret information with peace of mind as it is impossible to reassemble the shredded document by current scientific means.
