High security paper shredders must be evaluated by the NSA to ensure they produce waste particles less than 1mm x 5mm. The NSA also performs a durability test for one hour where the maximum amount of paper is shredded. All NSA evaluated shredders are listed on the Evaluated Products List (EPL) prepared by the NSA. Paper shredders are also evaluated and listed by the waste size through DIN. All NSA evaluated shredders are DIN level P-7 by DIN standard 66399. For very high volumes of paper destruction, SEM offers a complete line of NSA Listed disintegrators.
