Failing to use correct procedures for reducing samples to testing size can result in a _____.

Using correct procedures for reducing samples to the testing size is crucial in sampling and testing for various materials, including aggregate bases. When these procedures are not followed properly, the sample obtained may not accurately reflect the characteristics of the bulk material from which it was taken, resulting in a nonrepresentative sample.

A nonrepresentative sample means that the sample does not capture the variability and properties of the entire lot or batch. This can lead to incorrect conclusions or evaluations based on the laboratory tests performed on the sample. For example, if a sample is reduced improperly, it could under-represent or over-represent certain size fractions, moisture content, or composition, leading to flawed data that could impact the quality of construction or materials engineering decisions.

In this context, ensuring that sampling procedures are accurate and consistent is essential because it enhances the reliability of the testing results and ultimately influences project success.
