4.4 Test methods and procedures
4.4.1 Surface hardness of ball. -The surface hardness of
the bail shall be determined as follows: Mount specimen in
bakelite. The finished. surface shall be through the centerline
of the specimen within 0.003 inches and must be highly
polished and free from scratches and surface imperfections.
(Surface preparation should be Performed by using emery papers
of increasing fineness up to No. 000, followed by final
polishing on green and blue billiard cloths to provide the
specimen with a scratch-free surface where minimum disturbed
metal is present.) Using a Tukon microhardness tester with a
roo gram load 0.20, 0.25, and 0.30 millimeters from the edge
or the speciment. The average shall be taken of the three
readings and shall be between 438 and 576 on the Knoop hardness
scale. Failure to obtain an average reading~ within the
established limits shall cause the specimen to be classed
defective.
