ASTM E29 Standard Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications

ASTM E29 aims to help technical committees consistently identify significant digits in specification limits, such as maximum and minimum values. This document outlines methods for defining the meaning of specification limitations and comparing observed or computed test results to ensure conformance with requirements. This approach should be used to determine conformance with ASTM specifications or standards that specifically reference it.

    Introduction ASTM E29

    The Absolute Method and the Rounding Method are two widely used techniques for rounding data which are described in ASTM E29. It is essential to state which method is meant to be applied when applying this practice to a particular substance or material. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM E29 tests for our clients. ASTM E29 doesn’t give any preference as to which approach should be used, so it requires the presence of such a definition. The technique of choice is indicated in the primary publication because it is dependent on the existing practices of the specific sector or technology in question.

    ASTM E29 Test Method

    Rounding MethodWhen using the rounding method of ASTM E29, a calculated or observed number should be rounded to the closest unit. The rounded amount should then be compared to the designated limit, and depending on the comparison, the specification’s conformity or nonconformance should be determined.
    Absolute MethodWhen using the absolute technique of ASTM E29, a computed or observed number is compared straight to the designated limiting value rather than being rounded. Based on this comparison, conformity or nonconformance with the specification is determined.

    ASTM E29 Test Specimen

    Specimen DetailAny kind of specimen for which measurement is required is used.
    Specimen SizeIt is crucial to state which method is meant to be applied when applying this practice to a particular substance or material.
