"' Primary form "'is used in surface metrology to refer to the over-all shape of a surface which can be measured quantitatively, as contrasted with more local or higher-spatial frequency variations in the surface dimensions such as surface waviness or surface roughness or surface finish.

If under-deposit or crevice corrosion is of primary concern, it is important to note non-uniformity of deposit thickness ( e . g ., deposit waviness ), localized fouling, packing of confined regions with deposits, creation of occlusions, " crevices ", " deposit tubercles ", or sludge piles.

These include incomplete seating during the press fitting-step, distortion of the nominally circular valve seat surfaces such they deviate unacceptably from perfect roundness or waviness, tilt of the machined surfaces relative to the valve guide hole axis, deviation of the valve seat surfaces from concentricity with the valve guide holes, and deviation of the machined conical section of the valve seat from the cone angle that is required to match the valve surface.

The red and green of the walls and ceiling are an " oppressive combination ", and the lamps are " sinister features " with orange-and-green halos, according to Nathaniel Harris .
