system. The following schedule shall be adhered to for dosing: <br /> Time Frame Approximate %rated daily hydraulic capacity <br /> 6 a. m. —9 a. m. 35 <br /> 11 a. m. —2 p. m. 25 <br /> 5 p. m. —8 p. m. 40 <br /> NOTE—An individual dose shall be no more than 10 gal(37.9 L),unless the dosage system is based on a continuous flow, <br /> and the doses shall be uniformly applied over the dosing period. <br /> 8.2.2.2 Stress loading <br /> Stress loading sequences shall begin in week 17 of the testing and will be completed in the order listed in the <br /> following sections. Each stress sequence shall be separated by 7 d of design loading, as described in <br /> 8.2.2.1. <br /> 8.2.2.2.1 Wash-day stress <br /> The wash-day stress shall consist of 3 wash-days in a 5-d period. Each wash-day shall be separated by a <br /> 24-h period. During a wash-day,the system shall be loaded at times and capacities similar to those delivered <br /> during design loading (see 8.2.2.1). However, during the first two dosing periods per day,the design loading <br /> shall include 3 wash loads (3 wash cycles and 6 rinse cycles). <br /> 8.2.2.2.2 Working-parent stress <br /> For five consecutive days, the system shall be subjected to a working-parent stress. During this stress, the <br /> system shall be dosed with 40% of its daily hydraulic capacity between 6:00 a. m. and 9:00 a. m. Between <br /> 5:00 p. m. and 8:00 p. m., the system shall be dosed with the remaining 60% of its daily hydraulic capacity, <br /> which shall include 1 wash load (1 wash cycle and 2 rinse cycles). <br /> 8.2.2.2.3 Power/equipment failure stress <br /> Power/equipment failure stress simulation shall consist of a flow pattern where approximately 40% of the <br /> total <br /> daily flow is received between 5 p. m. and 8 p. m. on the day when the power/equipment failure stress is <br /> initiated. Power to the system shall then be turned off at 9 p. m. and the flow pattern shall be discontinued for <br /> 48 h. After the 48-h period, power shall be restored and the system shall receive approximately 60% of the <br /> total daily flow over a 3-h period which shall include 1 wash load (1 wash cycle and 2 rinse cycles). <br /> 8.2.2.2.4 Vacation stress <br /> Vacation stress simulation shall consist of a flow pattern where approximately 35% of the total daily flow is <br /> received between 6 a. m. and 9 a. m. and approximately 25% of the total daily flow is received between <br /> 11 a. m. and 2 p. m. on the day that the vacation stress is initiated. The flow pattern shall be discontinued for <br /> 8 consecutive days with power continuing to be supplied to the system.
