What does the density control sampling process include in terms of gauge readings?

The density control sampling process typically involves taking multiple readings from a section to ensure accuracy and reliability in the measurements. By averaging five individual readings, the process accounts for variations within the section's density, leading to more reliable data for quality control.

Using five readings helps to mitigate the impact of any outliers or discrepancies that might arise from a single measurement. This method offers a more comprehensive assessment of the material's density across the section, aligning with standard practices to ensure that the sampling adequately reflects the overall conditions.

Other approaches, such as using just one gauge reading or a different number of readings, may not provide the same level of assurance concerning the accuracy and representativeness of the density measurements. Therefore, averaging five individual readings is a well-accepted method within quality management systems to ensure robust density control sampling.
