ISO 12836:2015规定了间接牙科修复用计算机辅助设计/计算机辅助制造（CAD/CAM）系统数字化设备精度评估的试验方法。ISO 12836:2015中描述的方法需要一个数字化设备，其中物体相对于光学或机械接触系统安装，因此不适用于手持式扫描设备。 这些试验方法不适用于通过射线照相（X射线）方法或磁共振成像（MRI）方法进行数字化。

ISO 12836:2015 specifies test methods for the assessment of the accuracy of digitizing devices for computer-aided design/computer-aided manufacturing (CAD/CAM) systems for indirect dental restorations. The methods described in ISO 12836:2015 require a digitizing device in which the object is mounted relative to the optical or mechanical-contact system and therefore do not apply to hand-held scanning devices. These test methods are not applicable to digitization by radiographic (X-ray) methods or by magnetic resonance imaging (MRI) methods.
