Scope

Main technical content: The control of the thickness of the reinforcing bar protection layer is an important indicator for the quality evaluation of engineering projects by the Ministry of Transport, and it is also an evaluation indicator for the durability of components. In previous inspections, there were often phenomena such as random operation and unstable data. This test inspection procedure, starting from the basic situation of the instrument, uses measurement system analysis technology to determine the accuracy of the instrument, standardizes the inspection method, and provides a basis for the standardization of the inspection procedure for the thickness of the protection layer.
