Standards and Test Criteria

The ADS8686S EMC test board is designed to meet the EMC and EMI test standard and criteria for industrial applications. According to the standard, the following six tests are selected:

  • IEC 61000-4-2: Electrostatic Discharge (ESD)
  • IEC 61000-4-3: Radiated Immunity (RI)
  • IEC 61000-4-4: Electrical Fast Transients (EFT)
  • IEC 61000-4-5: Surge Immunity (SI)
  • IEC 61000-4-6: Conducted Immunity (CI)
  • CISPR 11: Radiated Emissions for EMI from industrial, scientific and medical (ISM) equipment

The test criteria is described in Table 2-1.

Table 2-1 Test Criteria
Criteria Description
A Normal performance within specified limits
B Temporary performance loss which can recover after disturbance ends
C Temporary function or performance loss which can recover with user's intervention
D Permanent function or performance loss due to damage or loss of data
