must be labeled according to this subpart, and must comply with the 

Labeled Values of mean attenuation.

    (b) A manufacturer must take into account both product variability 

and test-to-test variability when labeling his devices in order to meet 

the requirements of paragraph (a) of this section. A specific category 

is considered when the attenuation value at the tested one-third octave 

band is equal to or greater than the Labeled Value, or mean attenuation 

value, stated in the supporting information required by Sec.  211.204-4, 

for that tested frequency. The attenuation value must be determined 

according to the test procedures of Sec.  211.206. The Noise Reduction 

Rating for the label must be calculated using the Labeled Values of mean 

attenuation that will be included in the supporting information required 

by Sec.  211.204-4.
