Establishes main design features, general dimensions, material, finishes, methods and marking of support, and accuracies for cast-iron, steel and stone straightedges. It provides for three grades of accuracy and covers the range of sizes from 250 mm to 5000 mm in cast-iron and from 250 mm to 2000 mm in steel and in stone.

This standard relates to engineers' precision straightedges in metric units. It covers four standard types and provides for three grades of accuracy, as follows:Cast-iron Straightedges Bow-shaped Grades A and B Cast-iron Straightedges I-section Grades A and B Steel Straightedges Rectangular section Grades A and B Stone Straightedges Rectangular section Grades AA and AThe standard specifies requirements for dimensional accuracy, materials, general quality, finish, marking and packaging, together with those design features necessary to ensure convenience in use, rigidity, stability and durability of straightedges.It provides for two varieties of cast-iron straightedges differing in the accuracy of their side faces (see Clause 2.9) and designated Type N (normal) and Type S (special).NOTES:1. For engineers' straightedges in imperial units, see AS B307.2. For toolmakers' straightedges see AS B72.
