7.5.5. ESD TESTING CONSIDERATIONS Other Important Considerations for ESD Testing (planter example):

o Recognize the control we have over the entire system, so that the test setup at each level can be made more realistic than it could be otherwise (e.g., attach pin and mounting grounds for unpow-ered tests of a module, if considered appropriate; provide connected system components for powered tests of a module, if considered appropriate; attach grounding straps used in production, if considered appropriate; open seed meter and remove seed disk to expose actively spinning meter motor drive gear as a discharge point, if considered appropriate)

o Determine and use an appropriate ground-return point for the ESD simulator (e.g., unpainted structural bolt of row unit, planter frame or tractor chassis)

o Consider which of the different operating modes of the system to use for each powered test o Determine and vary the required number of pulses per test depending upon the expected type of

ESD source event (e.g., bulk seed delivery subsystem vs. human/tool touch) o Consider humidity levels for air discharge testing related to the need for repeatability o Determine method of ensuring that a full neutralization of the previous discharge event is

achieved before each new discharge event (e.g., providing adequate self-discharge delay time between ESD pulses vs. wiping with a 1 Meg-ohm metallic brush or a dissipative wrist-strapped hand)

o Screen for sensitive test areas by applying up to 50 discharges to various areas, moving on at any point that resulted in an abnormal behavioral result; focus final testing on those points that previously had an abnormal result; apply both positive and negative voltage polarities

o Consider for final testing at least 200 discharges per voltage level at each selected test point that could experience continual discharges in actual use (e.g., seed delivery sub-system components)

o Consider for final testing at least 20 discharges per voltage level at each selected test point that could commonly experience human/tool discharges in actual use (e.g., tablet touchscreen, man-ual run button on each row)

o Consider for final testing at least 10 discharges per voltage level at other selected points less likely to experience discharges in actual use (e.g., exposed connector shells)

o Consider the potential value of indirect discharge tests via indirect coupling planes or coupling into connected wire harnesses described in ISO 10605 and other standards

o Document actual test setups and test procedures thoroughly, including photos or other methods of recording temperature and humidity measurements during tests, ESD simulator make and model, discharge network, discharge mode, discharge tip used for each test, etc.

7.8. ELECTRONIC ENVIRONMENTAL TESTING SUMMARY

7.8.1. FUNCTIONAL PERFORMANCE STATUS LEVELS The performance of the module’s or system’s functions, when subjected to the test condition, is described by the four status levels in the table below, which may be used as the pass criteria requirement for a spe-cific powered test.

Status I The functions operate as designed during and after the test.

Status II The functions do not perform as designed at some time during the test but return

automatically to normal operation during and/or after the test.

Status III The functions do not perform as designed during the test and do not return auto-

matically to normal operation, but do return to normal operation after a simple

user intervention (e.g., power cycle.)

Status IV The functions do not perform as designed during the test and do not return to nor-

mal operation after a simple user intervention, but do return to normal operation

after a more extensive user intervention, such as disconnecting and reconnecting

the battery or power cable.

Table 9: Functional Performance Status Levels

7.8.2. FUNCTIONAL CLASSIFICATION GROUPS

To assign ratings to functions based upon their relative importance and use these as factors in pass/fail

requirements, module or system functions shall be divided into the four groups as defined in the table be-

low based on the criticality of each function.

Group A Any function that is only a convenience function provided by the module

Group B Any function that is beyond just a convenience function but is not an essential op-

eration and/or control function provided by the module

Group C Any function that is considered to be an essential operation and/or control func-

tion but is not considered a safety function provided by the module

Group D Any function that is considered to be a safety function provided by the module

UUT power cycled and operationally verified at specified points during test. (Figure 4)

Subject UUT to a thermal cycle shown in Figure 4. Use the upper/lower temperatures from the “Operating

Temperature” and “Storage Temperature” sections.

Dwell times shall be 80% of the time required for the component with the largest thermal mass to become

temperature stabilized.

Temperature is considered stabilized when the component believed to have the longest thermal lag

reaches a temperature of within 2ᴼ C of the specified temperature or critical components within 1ᴼ C of

specified temperature, whichever is greater.

Temperature transitions shall not be <5 °C/min.

Chamber temperatures may be temporarily adjusted beyond 5ᴼ C of the desired set point to reduce stabi-

lization time.
