3 Tests

All Nilfisk-Advance systems are tested in order to comply with the requirements of
system safety regulations. They have fulfilled the technical safety demands according
to the following special regulations:

- Technical Dust Test

- Mechanical and Electrical Test

- Noise Technology Test

DIN EN ISO 3744

- Additional Dust Explosion Protection Test

4 Categories of application

This Nilfisk machine is suitable for removing dusts of the following categories of
application:

“U“ suitable for removing hazardous, dry, not inflammable dusts whose MAK*

limiting value is greater than 1 mg/cm³ (comparable to the new dust class “L“

- light hazard - defined by EN 60335-2-69).

“S“ suitable for removing hazardous, dry, not inflammable dusts whose MAK

limiting value is greater than 0.1 mg/cm³ (comparable to the new dust class

“M“ - medium hazard - defined by EN 60335-2-69).

“C“ suitable for removing hazardous, dry, not inflammable dusts with all MAK

limiting values (comparable to the new dust class “M“) as well as dry, not
inflammable dusts of carcinogenic substances (comparable to the new dust
class “H“ – high hazard – defined by EN 60335-2-69). The cleaned air is fed
back to the workplace atmosphere.

“K1“ suitable for removing hazardous, dry, not inflammable dusts with all MAK

limiting values as well as dry, not inflammable dusts of carcinogenic
substances. The cleaned air is fed back to the workplace atmosphere
(comparable to the new dust class “H“).

*maximale Arbeitsplatz-Konzentration, maximal workplace concentration

Explanation

Since May 1998, Europe has a common norm. Dust removing systems are from now
on divided into three dust classes L, M and H. Older test certificates remain valid until
December 31st, 2002. “Category of application“ is a synonym for “dust class“.

Noise emission

Sound pressure level measuring as described in DIN EN ISO 3744.

According to the machine guideline Appendix 1, point 1.75 f, the highest sound
pressure level is measured at 1 m distance from the machine at a height of 1.6 m.
The highest value is reached on the right side (view down on the inlet):

77 dB(A).
