A range of inch rings (0.08 in to 6 in) in three grades of accuracy (AA, A and B). Accuracy of geometric form, maximum departures of mean measured size from nominal size, accuracy to which the measured size is to be determined. Also includes material, hardness, and surface texture.

1.1 This British Standard relates to plain setting rings primarily intended to be used, either singly or in combination, for checking the scales on internal diameter measuring equipment.

It provides for a range of inch rings in sizes from 0 08 in to 6 inches in three grades of accuracy, viz.

Grades AA, A and B.

NOTE Sizes below 0 08 in are not included because it is impracticable to measure them.

Requirements are specified for material, hardness and surface texture and recommended sections for the setting rings covered by this standard are included in an appendix.
