When did the American Wire Gauge system come into use? - 翻译中...
AWG was developed in 1856 by J.R. Brown and Sharpe, a small firm in Providence, Rhode Island that specialized in the crafting and repair of watches, clocks, and mathematical instruments. That same year, Lucien Sharpe presented the new system to the Waterbury Brass Association. Convinced that Brown and Sharpe's gauging system would greatly improve uniformity throughout the wire manufacturing industry, Waterbury Brass Association made a movement to adopt the standard. By February of 1857, eight major American manufacturers had signed resolutions to adhere to the Brown and Sharpe gauge standard; the following month, a nationwide circular was distributed, introducing the new wire gauge standard to the American public.
