The examples are not binding on products or test methods treated. Originally approved in Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
That is, the rounding unit for the speci? Digits of ln x or log10 x are signi? This standard is subject to revision at any time by awtm responsible technical committee and must be reviewed every?

asrm This abstract is a brief summary of the referenced standard. It should not be inferred that a measurement value is precise to the number of signi? Table 1 gives examples of applying this rounding procedure. When the measuring device has a vernier scale, the last digit recorded is the one from the vernier.
Excel: Round 0.5 towards Even Per ASTM-E29
Work Item s – proposed revisions of this standard. 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? Last previous edition ast in as E29 — Analyses on six specimens give values of 3.
Tensile Requirements Tensile strength, psi Yield e9, min, psi Elongation in 2 in. In the absence of such speci? The Modern Metric System 3. As far as is practicable with the calculating device or form used, carry out calculations with the observed values exactly and round only the? A test result is calculated as 1. Increase by 1 the digit in the last place retained, if there are e2 digits beyond this 5. 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.
ICS Number Code Zeros trailing the last nonzero digit for numbers represented with a decimal point are signi? When 12 is divided by 2, the resulting number, 6is the rounded value of 6 For example, a modulus strength, stated as Pa, may have as few as two or as many as six signi?
Dimensional quantities in the practice are presented only as illustrations of calculation methods. ASTM Manual 7 asm methods for reporting x? The following applies to speci?
In the applications of this practice to a speci? This practice is intended to assist the various technical committees in the use of uniform methods of indicating the number of digits which are to be considered significant in specification asym, for example, specified maximum values and specified minimum values.
Two commonly accepted methods of rounding data, identified as the absolute method and the rounding method are described.
If two choices are possible, as when the digits dropped are exactly a 5 or a 5 followed only by zeros, choose that ending in an even digit. For example, the number 0. The applicable standard deviation is the repeatability standard deviation. Guidelines astj Retaining Signi?
ASTM E29 – 13
The rounded value should then be compared with the speci? Current edition approved Aug. In such cases, the following procedure can be used for rounding to any interval: For example, if a buret is graduated in units of 0. This will be referred to as the rounding method,which is discussed in Section 2e9. Multiplying 4 by 0. The guidelines for retaining significant figures in calculation and reporting of aastm results are presented in details.
Rounding this value to the nearest whole number gives a value of 4, based on the information in 6. The average and standard deviation, atm, are x?

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
