Why is a BMR required when using Type I DFT measuring equipment?

A Brushing Measurement Reference (BMR) is essential when utilizing Type I DFT (Dry Film Thickness) measuring equipment because it serves the primary function of calibrating the equipment. Proper calibration ensures that the measurements taken by the DFT gauge are accurate and reliable. This process involves establishing a baseline or reference measurement against which subsequent readings can be compared. Accurate calibration is crucial, particularly in the field of coatings and inspections, where precise measurements dictate the quality and durability of the paint application.

Calibration using a BMR allows inspectors to verify that the equipment is functioning correctly and providing valid thickness measurements of the dried paint film on surfaces. It ultimately aids in ensuring compliance with project specifications and industry standards, which can significantly influence the longevity and performance of protective coatings.
