23、 figures used in expressing the limitingvalues in accordance with the rounding method of PracticeE29.1.10 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be us
