ASTM D8232-18 PDF Download

The ASTM D8232-18 standard provides test procedures for measuring the inclination of deep foundation elements, including those in the excavation stage. The standard emphasizes the importance of controlling pile inclination in order to avoid excessive bending moments and shear forces that can occur when a pile deviates from the planned inclination. It also highlights the potential consequences of excessive deviation, such as decreased basement space or gaps in adjacent piles that can lead to seepage or ground loss.

The standard includes two test procedures: Procedure A (Inclinometer Testing) for testing both open boreholes and constructed piles, and Procedure B (Pendulum Testing) for testing open boreholes. These procedures are described in detail within the standard.

It is important to note that the standard provides minimum requirements for measuring pile inclination, and additional requirements and procedures may be specified by a qualified engineer based on the objectives of a particular test program. The engineer is responsible for designing and approving the test configuration and test procedures.

The standard also provides guidelines for significant digits and rounding, as well as notes and footnotes that provide explanatory material. However, these notes and footnotes should not be considered as requirements of the standard. Additionally, the standard specifies that the procedures used for data collection, recording, and calculation are representative of the significant digits that should generally be retained, but the user may adjust the significant digits based on material variation, purpose of data collection, and other considerations. The standard does not address significant digits used in engineering design analysis methods.
