Ibid., There was very little difference noted in the hardness at the center, or the outside, and a Brinell test was then made... The diameter of the depression was measured under a microscope and the corresponding Brinell number calculated. 1916Metal Industry 25 Aug. 236 (title) Testing non-ferrous metals for hardness: application of the Brinell method.
