If there are irregularities on the SFRM thickness test surface, what is the recommended action?

Thickness readings rely on a uniform, flat surface. When the test surface has irregularities, the gauge can seat unevenly or read areas that aren’t representative, leading to inaccurate thickness results. The best action is to move the thickness gauge to the nearest area that has a more uniform surface so the measurement reflects the actual installed thickness. This helps ensure the reading is reliable and compliant with the specification. If no uniform spots are available, take multiple readings in several uniform areas and average them rather than relying on a single uneven location. Avoid random spots or skipping the test, as these choices undermine measurement accuracy.
