Rounding so that w is below s29.

This standard has been approved for use by agencies of the Department of Defense. For example, if a buret is graduated in units of 0. In the applications of this practice to a speci? Two commonly accepted methods of rounding data, identified as the absolute method and the rounding method are described.

A number in parentheses indicates the year of last reapproval. Thus, kPa without the decimal point indicates that the modulus is reported either to the nearest 10 or 1 kPa, which is ambiguous with respect to the number of signi? The applicable standard deviation is the repeatability standard deviation. Its aim is to outline methods which should aid in clarifying the intended meaning of specification limits with which observed values or calculated test results are compared in determining conformance with specifications.
