3 Classification

The TIDA-010263 test board is designed to meet the EMC and EMI test standard and criteria for industrial applications. According to the standard, the following 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)
  • IEC 61000-6-3 EMCL DC Conducted Voltage Emissions
  • CISPR 32: Radiated Emissions for EMI from industrial, scientific and medical (ISM) equipment
Table 3-1 Classification Matrix
Performance (Acceptance Criterion)Description
AModule shall continue to operate as intended. No loss of function, performance and no Ethernet packets are corrupted, even during the test
BTemporary degradation of performance during test is accepted. After the test, module shall continue to operate as intended without manual intervention
B*Module shall continue to operate as intended. No loss of function or performance even during the test. Some data packets can be missing, but communication is not completely link loss
CDuring the test, loss of functions accepted, but no destruction of hardware or software. After the test, module shall continue to operate as intended automatically, after manual restart, or power off, or power on. Not self-recoverable

Definition of Criterion A is customer-dependent:

  • For communication interfaces often less than three consecutive errors are still considered Criterion A.
  • Customers typically test twice the standard voltages.
  • Achieving criterion A, especially with EFT is a competitive advantage.

-> Yields to more robust system with better performance and less downtime in a harsh industrial environment
