GAR C-9 Cast Microfinish Comparator Surface Roughness Scale

The C-9 Cast MICROFINISH COMPARATOR Surface Roughness Scale is made by a dual electroforming process wherein nickel is electrodeposited to provide an exact reproduction in intricate detail.The same electroforming process used to produce the Surface Roughness Scale is available from GAR Electroforming to serve your product needs.

The C-9 Cast MICROFINISH COMPARATOR Surface Roughness Scale provides industry with established flat surface roughness specimens for visual and tactual comparison. It is used in specifying and controlling surface roughness when a product having the appearance of typically cast surfaces is required.

The C-9 Cast MICROFINISH COMPARATOR Surface Roughness Scale provides an economical tool which permits roughness to be specified on the same basis as linear measurements. The surfaces presented are the result of years of research and engineering. Details covering this subject are now published in The American National Standards Institute (ANSI) specification titled: "Surface Texture, Surface Roughness, Waviness and Lay." ANSI/ASME B46.

The C-9 Cast MICROFINISH COMPARATOR is rectangular in shape (4 1/2"x 3 1/4") and is a corrosion resistant electroformed nickel duplicate of actual cast surfaces.

There are nine replicated cast surface finish specimens ranging from 20 to 900 microinches.

The C-9 MICROFINISH COMPARATOR is supplied in a leatherette case with engineering data and instructions.
