Common use of Determination of the detection distance Clause in Contracts

Determination of the detection distance. 1.3.1. Maximum detection distance within the critical viewing distance where, due to the installation, the distance eye-monitor is less than the critical viewing distance, the maximum attainable detection distance shall be defined by: rd = D0 = ⎛ f .ω ⎞ D0 ⎛ f .β ⎞ tan⎜ c ⎟ tan⎜ c ⎟ where: ⎝ 60 ⎠ ⎝ 0.Xx ⎠ rd - detection distance [m] Do - diameter of the object [m] ƒ - threshold increasing factor ωc , βc and Nc according to paragraph 1.1. D0 = 0.8 m ƒ = 8 1.3.2. Detection distance greater than the critical viewing distance. Where, due to the installation, the distance eye-monitor is more than the critical viewing distance, the maximum obtainable detection distance shall be defined: rd = D0 ⎡ f .β N ⎛ ω ⎞⎤ tan⎢ c . x .x . xxx⎜ eye ⎟⎥ where: ⎢⎣ 2Nc 0,00000.Xx ⎝ 60 ⎠⎥⎦ rm - viewing distance to the monitor (m) Dm- diagonal of the monitor screen (inch) Nm- number of video lines of the monitor (-) βc and Nc according to paragraph 1.1.
