EN 169
EN 172
Suitable for use in activities related to grinding, soldering and welding (IR),
protects against direct sunlight (UV) as well
Welding 5
5 2% EN 169
They protect against infrared (IR) radiation during gas welding and brazing
where gas flow rate (quantity of acetylene introduced into the flame) is max.
200 liters/hour and oxygen flow is max. 2,000 liters/hour for oxy-fuel cutting.
Welding 7
7 1% EN 169
They protect against infrared (IR) radiation during gas welding where gas
flow rate is max. 800 liters/hour and oxygen flow is max.
8,000 liters/hour for oxy-fuel cutting.
Cobalt blue 4-6 1.5% EN171
Protection against infrared and blinding light, yellow-orange radiation in
glass and metal industry, checking molding temperature in metallurgy
Reflective
coating
its miniscule metal particles help reduce the amount of light hitting the eyes in blinding lights
Polarized
coating
filters out reflections off smooth surfaces and glaring horizontal sunlight (snow, water surface, bright sand,
buildings with glass walls), helps improve feature and contrast perception
UV400
coating
filters out 100% of UV-A and UV-B and provides additional protection against blue light up to 400 nm
