- The X-Series earmuffs are 3M's latest advancement in hearing conservation
- New technologies in comfort, design and protection all come together in this groundbreaking earmuff line
- The X1A is a lightweight, low- profile earmuff designed for protection against low-level industrial noise and other loud sounds
- It features an electrically insulated wire headband, often referred to as "dielectric"
- The wire headband offers consistent pressure over prolonged wearing periods
- Earcup pivot points tilt for optimum comfort and efficiency
- Noise Reduction Rating (NRR)b 22 dB
- CSA Class A
- NOTE: The X-Series (over-the-head) headband version is electrically insulated - sometimes referred to as"dielectric"
- The metal components of the headband 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 ear muffs against electrical insulating properties, the product has been evaluated at an external laboratory against a modified 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 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
