Frequently Asked Questions
Can it really shred CDs and DVDs?
Yes. The C18 5.8 mm carries an O-2 rating under DIN 66399, which means it is specified for optical data carriers. Feed discs one at a time and alone, not sandwiched in a paper batch. O-2 is a low level of destruction for optical media - the pieces are large - so it is adequate for scratch discs and superseded software, not for a disc holding personal or financial data. For that you want an O-5 or O-6 dedicated cutting unit, as on the P36i OMDD models.
How does it compare with the C16 5.8 mm?
Same 5.8 mm strip, same P-2 level, same 6.6 gallon container. The C18 has a 360 W motor against the C16's 185 W, takes 17 to 19 sheets instead of 15 to 17, has a slightly wider 230 mm throat, adds the O-2 optical media rating, and weighs 21.6 lb against 8.8 lb. If you want discs handled or a machine that feels less strained under a load, the C18 earns the difference.
Is 17 to 19 sheets realistic in daily use?
It is HSM's rating at 80 g/m2 paper. US 20 lb copy stock is a little lighter, so the top of the range is achievable with flat, unfolded sheets. Folded, stapled or glossy paper counts for more than one sheet each. As a planning number, treat 15 sheets as the comfortable working load and keep the top of the range for occasional use.
How often will the bin need emptying?
HSM rates the 25 l container at roughly 165 sheets of 5.8 mm strip waste - a low figure, because strips fluff rather than pack. At the throughput this machine is capable of you could fill it in a single sitting. Plan on emptying it every day or two if you are using its capacity. The cross-cut C18 fits over twice as much paper into the identical container.
Is this shredder NSA approved?
No. NSA/CSS 02-01 requires a maximum particle size of 1 mm x 5 mm and the specific model to appear on the NSA/CSS Evaluated Products List. A 5.8 mm strip-cut machine meets neither condition, and the C18 is not on the list. HSM does have listed models - the SECURIO P36i (L6) and P36i (L6) OMDD Combo appear on the current EPL - but they are 1 x 5 mm micro-cut departmental machines, not desk-side units.
Can it run continuously through a large backlog?
No. The C18 is a personal shredder with a duty cycle intended for intermittent use. Work in batches and let it rest if it slows or gets warm; overload protection will stop it before damage occurs. A one-off backlog of several thousand pages is a job for a departmental machine such as the SECURIO P36i, which HSM rates for continuous running.
