FAQ Eye & Face Protection

All personal protective equipment (PPE) sold on the European market, must be CE marked and in compliance with the PPE Directive 89/686/EEC. To show compliance with the basic safety requirements specified in the PPE Directive, you can have the PPE tested and certified to harmonized standards, for example EN 175 Personal protection – Equipment for eye and face protection during welding and allied processes. The European Committee for Standardization (CEN), that the National Standardization Bodies are members of, develops the European standards for personal protective equipment.

For more information about safety standards in your country, please contact your National Standards Institute.

Grinding and mechanical strength (European Standards)

In general for grinding applications; Due to the nature of the hazard, it is recommended to use eye and face protection that is certified to EN166 and/or EN175 as a class “B”-device. A class B-device meets the requirements for protection against high-speed particles from a medium energy impact of a steel-ball travelling with a velocity of 120 m/s. The classification for mechanical strength can be complemented with the letter “T”, to show that it meets the requirement, for the protection against high-speed particles, at extremes of temperatures (-5° C and +55° C). Class “F”-devices resist the impact of a steel-ball that travels with a velocity of 45 m/s and are not recommended by 3M for use in grinding applications.

Below you can find the classification for our products, they can also be identified from a label inside your helmet.

Classification of mechanical strength (European Standard):

Class S: Increased robustness (drop ball test 5.1 m/s)

Class F: Resistance to high speed particles at low energy impact (45 m/s)

Class B: Resistance to high speed particles at medium energy impact (120 m/s)

Class T: The letter ‘T’ indicates that the test for resistance to high speed particle was conducted at extremes of temperature (-5⁰C and +55⁰C) – optional

Note: Products classified in class B are not made to give total protection under all possible circumstances, e.g. when using grinding wheels/grinding machines

9100FX_action_13_30x21The mechanical strength of all 3M™ Speedglas™ Welding Helmet Series 9100 are approved to EN 175:B and EN 166:BT, while the older model 3M™ Speedglas™ Welding Helmet 9000 with side windows is approved to EN 175:F.  Therefore, if you apreciate the side windows option and you use your helmet for grinding, 3M strongly recommends the choice of Speedglas helmet series 9100 over the older models with side windows.

Inspired by your reality

More than 35 years ago, we went to the shipyards of Sweden to study welders working conditions. We found skilled craftsmen blindly striking arcs as they continually nodded their shields down.

From that point on, we committed ourselves to developing tools that would forever improve the world of the welder. Your thoughts and opinions are the bottom line in our continuous search for innovation. Please feel free to address any questions or comments you might have.
