Specification Sheet
*The Optime
TM
number is a guideline for the maximum time-weighted average A-weighted exposures in which the product, when properly worn and in good condition, can provide adequate
protection to meet OSHA hearing conservation guidelines. However, the user must make sure that the specic muff and style selected provides appropriate protection. To be effective, the
hearing protector should be used within a hearing conservation program that also includes noise level assessments by qualied personnel, training, audiometric testing and engineering
controls. Optime number recommendations are based upon testing per Method B of the most recent ANSI standard, S12.6-1997 (R2002). Method B provides data that approximate the upper
limits to attenuation that can be expected for groups of occupational users. Properly trained and motivated individuals can potentially obtain greater protection. For additional information on
Method B visit www.e-a-r.com/hearingconservation and select the EARLog series of articles.

These hearing protectors help reduce exposure to hazardous noise and
other loud sounds. Misuse or failure to wear hearing protectors at all
times that you are exposed to hazardous noise may result in hearing
loss or injury. For proper use, see supervisor, Fitting Instructions, or call
3M in U.S.A. at 1-800-243-4630. In Canada, call Technical Service at
1-800-267-4414.
**Electrically-Insulated Headband. The metal components of the X Series standard headband model have been covered by non-conductive material for use in a low voltage electrical hazard (less
than 440 V ac). As there are no applicable standards for testing earmuffs against electrical insulating properties, the product has been evaluated at an external laboratory against a modied test
method based on EN397:1995. During assessment, the leakage current did not exceed 1.2mA when the external surface of the product made contact with an electrical source. The user must
determine the overall suitability of this product for the intended application taking into account any hazards other than noise for which this product is tested.
†The Noise Reduction Rating (NRR) may overestimate the hearing
protection provided during typical use. 3M recommends reducing the
NRR by 50% for estimating the amount of noise reduction provided.
