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 metric rings in sizes from 2 mm to 150 mm in three grades of accuracy, viz.
Grades AA, A and B
NOTE Sizes below 2 mm 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.
