8.3.14 Engineering Tests of Car Door Restrictors
The device, except self-lubricating bearings and bearings of a type not requiring frequent replenishment of lubricant, shall then be taken apart and freed of lubricant by washing in nonflammable liquids having cleansing characteristics.
After reassembly, the device shall, without other than the usual initial adjustment (i.e., without adjustment especially made to meet the conditions of the particular test] and without further attention, complete 25000 cycles of operation without failure of any kind, without excessive wearing or loosening of parts. This test shall not be required for car door restrictors that do not have moving parts.
The device shall be subjected continuously, in an unventilated enclosure, to an atmosphere saturated with a range of 3.5% to 5% solution of sodium chloride for 72 consecutive hours. During this period, it shall be operated for only 10 consecutive cycles at the end of each of the first two 24 h periods and shall be allowed to stand exposed to the air for 24 h, and shall not fail in a manner that creates an unsafe condition.
The device shall again be lubricated and shall, without adjustment and without further attention, complete 15 000 cycles of operation without failure of any kind. This test shall not be required for car door restrictors that do not have moving parts.
