Application
Eye protection must protect against one or more of the following effects:
• Mechanical - flying fragments or particles, for example when grinding or polishing.
• Chemical - contact with harmful or corrosive substances such as caustic soda or acid.
• Optical - for example by welding, terminal work, and in contact with laser radiation.
Types of safety eyewear
The different types of eye protection can be divided into:
• Spectacles - covers only the eyes, does not close tightly, have side shields
• Goggles - covering the eye area, tight fit but can also be vented and thus not sealed against liquids and gases.
• Visors - covering most of the face, barrier against flying particles and liquids
• Shields - covering the entire face, barrier against flying particles and light
Properties
Always choose safety eyewear for the task it must resolve. Then focus on comfort, because if the eyewear is not comfortable, then it will not be worn. Do not underestimate the design. A smart spectacles that suits one's personality will be used more!
The range of safety eyewear at ICM is very big and there is no reason to compromise. One model does not fit all, and it is important that you feel comfortable with your safety eyewear in order for you to wear it all the time - even for shorter jobs.
Relevant standards
EN 166: Personal Eye protection
EN 169: Filters for welding and related techniques
EN 170: Ultraviolet filters
EN 171: Infrared filters
EN 172: Specification for sun glare filters used in personal eye-protectors for industrial use
EN 175: Equipment for eye and face protection during welding and allied processes
EN 207: Filters and equipment used for personal eye-protection against laser radiation
EN 379: Welding filters with switchable luminous transmittance and welding filters with dual luminous transmittance
ICM's goggles and visors are generally approved as per EN 166, but they can also be approved in accordance with other relevant standards. Eye protection approved to EN 166 can be labeled with one or more symbols that indicate the characteristics and scope.
See table.
In cases where the lenses and frame of the safety ey ewear are not classified the same, e.g. if the symbol for mechanical properties are different, then the complete eyewear is approved to the lowest ranking of the two classes.
Protective lenses
The lenses of safety eyewear can be made of different materials with very different properties. Typically used:
• Acetate - Plastic Material particularly suitable for work with chemicals and solvents.
• Polycarbonate (PC) - Strong, tough and the material with the greatest mechanical impact strength. However, easy to scratch and often applied with an anti scratch coating. PC protects against UV radiation.
• Laminated glass - two thin plastic plates glued together with plas
tic film. Poor mechanical strength, but very scratch resistant.
