For example, the numbers Current edition approved Aug. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This abstract is a brief summary of the referenced standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and e229 the applicability of regulatory limitations prior to use.

In order to round to the nearest 50, 5, 0.

The choice of method depends upon the current practice of the particular branch of industry or technology concerned, and should therefore be speci? 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.

The conversion constant, The rounding interval for test results should not be greater than 0. Under these conditions, the speci? Multiplying 4 by 0. Originally approved in For example, in rounding 6 to the nearest 50, 6 is doubled giving 12 which becomes 12 when rounded to the nearest 6. In such cases, the following procedure can be used for rounding to any interval: For example, a modulus strength, stated as Pa, may have as few as two or as many as six signi? ASTM Manual 7 provides methods for reporting x?


Its aim is to outline methods which should aid in clarifying the intended meaning of speci? Round test results to the place of the? This will be referred to as the absolute method, which is discussed in Section 5.

The number of signi? For purposes of determining conformance with these speci? NOTE 2—Using a calculation subroutine astj has been programmed to perform the rounding procedure described in 6.

Analyses on six specimens give values of 3.

In the applications of this practice to a speci? Write down the standard deviation.

A number in parentheses indicates the year of last reapproval. Its aim is to outline methods which should aid in clarifying the intended meaning of specification limits with which 2e9 values or calculated test results are compared in determining conformance with specifications. Conformance or nonconformance with the speci? When 12 is divided by 2, the resulting number, 6is the rounded value of 6 This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?


Dimensional quantities in the practice are presented only as illustrations of calculation methods. That is, the rounding unit for the speci? If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

The examples are not binding on products or test methods treated. Rounding this value to the nearest whole number gives a value of 4, based on the information in 6.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The following guidelines are intended to e2 the data for statistical summaries. It should not be inferred that a measurement value is precise to the number of signi?

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?
