1.WCR 00.00EA-D11-22 /Table3.3 / 4.1.1.1Performance Evaluation
a.Component performance parameters with quantifiable acceptance criteria/limits
(e.g. voltages, current,frequencies,input/output characteristics,display intensities,
computations etc)
b.Minmum ,maxmum and Nominal Temperatures(T3,T4and T
N
respectively)for
performance evaluations.Temperature selection should be in accordance with
Tables3.2.1.(a)and 3.2.1.(b)
c.Minmum ,maxmum and Nominal test supply voltages(V3,V4,V
N
respectively)
should be in accordance with Table 3.2.1.(a) and 3.2.1.(b).
2.WCR 00.00EA-D11-22 /Table3.3 / 4.1.1.2 Functional Check
a.Identification of the characteristics necessary to verify satisfactory function after
each environmental stress.Qualitative requirements for the characteristics should
be define.
b.Supply voltage and temperature (V5 and T
N
)per Tables 4.(b),3.2.1.(b)and3.2.6.(b)
3.WCR 00.00EA-D11-22 /Table3.3 / 4.1.1.3 Monitored Operation
a.Functional or performance characteristics with quantifitable criteria/limits nesessary
to determine satisfactory operation during exposure to the envireonments.
Note:Characteristics should be determined based on subsystem operational requirements,
functional importance class,FMEA's applicable regulatory/safety reauirements,company
standards and the "Typical Environmental Effects"listed in Table 1.2.2.Supply voltage,V6 as
specified in Tables 4.(b)and 3.2.6.(b).
4.WCR 00.00EA-D11-23 /Table3.3 / 4.1.1.5Visual Check
Comprehensive listing of visual characteristics with suffcient qualitative criteria to determine
functionability or degardation resulting from exposure to the environments.
Note:The characteristics and criteria should be based on vehicle requiremnets,subsystems
requirements,corporate standards,and "Typical Environmental Effects" listed Table1.2.1.
5.WCR 00.00EA-D11-23 /Table3.3 / 4.1.1.6Internal Inspection
Comprehensive listing of intermal visual characteristics or physical analysis,with sufficient
qualitative criteria that can determine degardation of interconnections and function. Specific
criteria should include "Typical Environmental Effects"from Table 1.2.1.as applicable.
6.WCR 00.00EA-D11-24 /Table4.(a) / 4.5.1 Low Temperature Exposure
Temperature -40℃
Duration 72hrs
Expose the component(non-operating)to minimum storage
temperture for 72 hours.
All testing according as EESE CORPORATE STANDARD for ENVIRONMENTAL
REQURTEMENTS-(Non-EMC) form Ford Motor Company
