What are the numbers stamped into my welding helmet?

The 2003 on the helmet and the hang tag is referring to the ANSI Z89.1-2003 standard for industrial head protective helmets.  It signifies our helmets meets the requirements classified as Type I for top protection or Type II for top and lateral impact protection. Both types are tested for impact attenuation and penetration resistance.  If you look at the lettering before the 2003, you will see ANSI-Z89.1 before it. Find out more about ANSI requirements here.
