Standards
These hearing protectors have been produced to
comply with the requirements of the Australian /New
Zealand Standard AS/NZS 1270:2002.
Laboratory Attenuation Values
Hearing protector Class 3 tested to AS/NZS 1270. When
selected, used and maintained as specified in AS/NZS 1269,
this protector may be used in noise 95 dB(A) to less than
100dB(A), assuming an 85dB(A) criterion.
A lower criterion may require a higher protector class.
Mean = Mean attenuation value derived from testing in
accordance with AS/NZS 1270:2002.
SD = Standard Deviation derived from testing in accordance
with AS/NZS 1270:2002.
Mean-SD = Mean attenuation value minus Standard Deviation
SLC80 = Single number rating commonly used in Australia
and New Zealand to compare acoustic performance of
hearing protectors. The subscript ‘80’ indicates that in
well managed hearing protector programs, the protection
provided is expected to equal or exceed the SLC80 in 80% of
protector-wearer noise spectrum combinations.
Class = A simplified process for selecting hearing protectors
based on the wearers 8-hour equivalent continuous
A-weighted sound pressure level.

SLC 80 18dB (Class 3)
3M strongly recommends personal fit testing of hearing protectors. Research
suggests that users may receive less noise reduction than indicated by the
attenuation label value(s) on the packaging due to variation in fit, fitting skill, and
motivation of the user.
