What does ANSI 297.1 on glass mean?
Tuesday, July 17, 2018
It is the number of the ANSI (American National Standards Institute) standard for safety glass. Since it is updated every few years, the standard number is usually followed by the year of the revision that it meets, which also means that the glass was manufactured with a few years of that year.
