TESTS
This product meets the Basic Safety Requirements as laid out in Annex II of the EC Directive 89/686
and the requirements of the EMC directive 89/336/EEC for CE marking in accordance with EN352-
1:1993, EN352-4:2001, EN55013, EN50082-1 and EN55020. The product is tested and approved by
BIA, Alte Heerstr., 111, D-53757 St Augustin, Germany (0121).
ATTENUATION VALUES (figure K)
The attenuation values of the hearing protectors are tested according to EN 24869-1 (with the elec-
tronics switched off) by BIA and the results are noted in the table in figure K. Explanation:
Type of hearing protector
75300 Sordin Supreme Basic
75301 Sordin Supreme Basic
75302 Sordin Supreme Pro
Attenuation value (figure K) explanation
F = Frequencies where attenuation value is measured.
Mf = Mean value,
sf = Standard deviation,
APV (Mf–sf) = Assumed Protection Value
H = High frequency attenuation value (predicted noise level reduction for noise with LC–LA = –2 dB)
M = Medium frequency attenuation value (predicted noise level reduction for noise with LC–LA = +2
dB)
L = Low frequency attenuation value (predicted noise level reduction for noise with LC–LA = +10 dB)
SNR = Single Number Rating (the value which is subtracted from the measured C-weighed sound
pressure level, LC, in order to estimate the effective A-weighted sound pressure level inside the ear)
W = Gross weight of the hearing protector in gram, not including batteries
The attenuation values apply using hygiene kit art. No.: 60089 (Figure K)
CRITERION LEVELS (figure L)
Typical values in accordance with EN 352-4:2001, appendix A, with the volume set to maximum.
Table (figure L) key:
H = High frequency sound pressure level (LC–LA = 1.2 dB)
M = Medium frequency sound pressure level (LC–LA = 2 dB)
L = Low frequency sound pressure level (LC–LA = 6 dB)
