This Standard defines preferred number and tabulates the basic series R5, R10, R20, R40 and R80. It includes general guidance on their use and deals particularly with the more rounded values tabulating both a first rounding and a second rounding. An Appendix describes precision of the values and regularity of the ratio.
This Standard defines preferred numbers and a series of preferred numbers. The Standard includes a guide to
- (a) the use of preferred numbers and a series of proposed numbers (see Section 3); and
- (b) the choice of series of preferred numbers and of series containing more-rounded values of preferred numbers.
The precision of values and the regularity of the ratio used is discussed in Appendix A.
