Field notes
The homepage describes a searchable reference organized by material, grade, and standard, with units and conditions attached to values. It says each citation records a source page and check date, and that conflicting sources are retained with a likely explanation. A comparison tool is described as accounting for thickness; the site also cautions readers to confirm values against the specified standard edition and the mill certificate for the delivered product.
