for a start. Don't let the line breaks mess you up.

Incidentlly, 2S, 4S, are properly written S2S and S4S and are not grades, but conditions of the sides: surfaced 2 sides; surfaced 4 sides.

Here is "softwood plywood"

is "hardwood plywood"

think you get the idea that there are several "standards" although most of the same terms apply many times...
