1. Tolerance zone is defined by its magnitude (i.e. tolerance) and by its position in relation to the zero line. T
2. In case of quilateral tolerances the total tolerance is specified on both side (Plus and Minus) of the basic dimension. F
3. The closer the tolerance, the higher the cost and the greater the chance of rejection. T
4. The nominal size of a dimension or part is the size by which it is referred to as a matter of convenience. T
5. Bilateral tolerances usually have plus and minus tolerance of equal amount. T
6. Tolerance are basically specified in three forms, i.e. unilateral bilateral and limiting dimension. F
7. The diameter of a shaft is written in mm as 20±0.02, it gives the tolerance 0.04 mm or 20 mm diameter. T
8. Standard tolerance is a tolerance belonging to any one of the standard grades. T
9. In bilateral tolerance as related to a basic dimension is in one direction only. F
10. The basic size should be midway between upper and lower limits. T
