Each oil buffer with oil portings as submitted shall be adjusted to tests for retardation, strength, oil leakage, plunger return, and lateral movement of the plunger, as hereinafter specified. 902.5a - Retardation Test 902.5a The following drop test shall be made for each buffer porting specified in Part II, Section 201, Rule 201.4g(1), from a height such that the striking velocity of the falling weight will be equal to one hundred and fifteen (115) per cent of the rated car speed for which the buffer is designed. 1. Three (3) drop test, with a total test weight equal to the manufacturer's rated maximum load for which the porting is designed (See Part II, Section 201, Rule 201.4g-la). 2. One (1) drop test with a total test weight equal to the manufacturer's rated minimum load for which the porting is designed (See Part II, Section 201, Rule 201.4g-lb). Following each drop test, the buffer shall be held in its fully compressed position for a period of five (5) minutes; and shall then be allowed to return freely to its fully extended position, and stand for thirty (30) minutes, to permit return of the oil to the reservoir and to permit the escape of any air entrained in the oil. On each of these tests the average retardation of the test weight, over the stroke of the buffer, shall not exceed thirty-two and two tenth (32.2) feet per second per second; and any retardation peak having a duration of more than one twenty fifth (1/25) of a second shall not exceed eighty and one half (80-1/2) feet per second per second. 95 TEXTO EN ESPAÑOL USAS, A17.1 3.
