Ceramic components must conform to certain visual specifications. PI Ceramic has set its own criteria for the quality assessment of the surface finishes, which follow the former MIL-STD-1376 standard. A large variety of applications are taken into account, for special requirements there are graduated sorting categories. A general rule is that visual peculiarities must not adversely affect the functioning of the component.
