Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. The number of signi?

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. An alternative statement of the suggested rule is: Tensile Requirements Tensile strength, psi Yield point, min, psi Elongation in 2 in.

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?

As far as is practicable with the calculating device or form used, carry out calculations with the observed values exactly and round only the? Guidelines for Retaining Signi? Round test results to the place of the? In the applications of this practice to a speci?


Its aim is to outline methods which should aid in clarifying the intended meaning of specification limits with which s29 values or calculated test results are compared in determining conformance with specifications. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

It is the responsibility of sstm user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

A test result is calculated as 1. If two choices are possible, as when s29 digits dropped are exactly a 5 or a 5 followed only by zeros, choose that ending in an even digit.

The suggested rule would report x? The applicable standard deviation is the repeatability standard deviation. Last previous edition approved in as E29 — 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? Thus, any deviation, however small, outside the speci?
