Oil-Buffer Safety) Type C Safeties may be used subject to the following requirements: 1. The rated speed shall be not more than five hundred (500) feet per minute. 2. The oil buffers shall conform to all requirements specified in Section 201 for oil buffers, except that the stroke shall be based on governor tripping speed and on an average retardation not exceeding 32.2 feet per second per second. 3. After the buffer stroke, as defined in Subdivision 2, has been completed, provision shall be made for an additional travel of the plunger or piston of not less than ten (10) per cent of the buffer stroke to prevent excessive impact on the buffer parts and the auxiliary safety plank. 4. Where the distance between guide rails exceeds eight (8) feet, the safety shall be provided with two (2) oil buffers of substantially identical calibration; and the buffers shall be so located as to develop minimum stresses in the auxiliary safety plank during safety operation. Buffers shall be located in line with and symmetrically between the guide rails. 126 TEXTO EN ESPAÑOL USAS, A17.1
