This will be referred to as the absolute method, which is discussed in Section 5. This abstract is a brief summary of the referenced 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?

Current edition approved Aug. In such cases, the following procedure can be used for rounding asmt any interval: The choice of method depends upon the current practice of the particular branch of industry or technology concerned, and should therefore be speci? In order to round to the nearest 50, 5, 0.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. An alternative statement of the suggested rule is: Reporting s to within 0. A number in parentheses indicates the year of last reapproval. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

The suggested rule would report x? In the absence of such speci? It is the responsibility of the user of this standard atm establish ast, safety and health practices and determine the applicability of regulatory limitations prior to use. For example, in rounding 6 to the nearest 50, 6 is doubled giving 12 which becomes 12 when rounded to the nearest 6.


NOTE 2—Using asym calculation subroutine that has been programmed to perform the rounding procedure described in 6.

For example, a modulus strength, stated as Pa, may have as few as two or as many as six signi? Last previous edition approved in as E29 — Rounding this value to the nearest whole number gives a value adtm 4, based on the information in 6. For example, the number 0.

The examples are not binding on products or test methods treated.

Tensile Requirements Tensile strength, psi Yield point, min, psi Elongation in 2 in. E229 rounding interval for test results should not be greater than 0. Multiplying 4 by 0. The ast, for retaining significant figures in calculation and reporting of test results are presented in details. 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. Write down the standard deviation.

It should not be inferred that a measurement value is precise to the number e299 signi? The following applies to speci? The standard deviation of the test method is estimated to be, 0.

Table 1 gives examples of applying this rounding procedure. Originally approved in Dimensional quantities in the practice are presented only as illustrations of calculation methods.

The examples are not binding on products or test methods treated. The following guidelines are intended to preserve the data for statistical summaries.

The conversion constant, This standard has been approved for use by agencies asmt the Department of Defense.

Increase by 1 the digit in the last place retained, if there are non-zero digits beyond astk 5. For certain purposes, such as where calculations involve differences of measurements close in magnitude, and for some statistical calculations, such as paired t-tests, autocorrelations, and nonparametric tests, reporting data to a greater number of signi? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
