I have a question from a faculty member here:
So what is the legal designation for students in chemistry labs for safety glasses. I thought it was ANSI Z87.1, however the ones the Lyceum sells are Z87+; and I have a student wants to know if just Z87 is legal.
My interpretation based on the information I see on the web is that Z87.1 is the designation of the standard and Z87 on the glasses indicate that they are tested for impact protection and Z87+ protects for higher impact. Is that correct?
Thanks for any help with this.
