Scope

This standard specifies a test method for determining the X-ray opacity of materials using a standard aluminum plate as a reference. This method is designed to distinguish X-ray opacity at a clinically significant level, without considering factors affecting accuracy or intrinsic factors affecting X-ray opacity (such as background noise, X-ray energy, gray-scale calibration, and image enhancement). Although these factors can change the numerical value of X-ray opacity, they cannot change the corresponding trend compared with the standard thickness of the reference material (such as aluminum). This test can be performed using traditional or digital sensing technology in dental X-ray machines.
