Immunity Testing
Typical Products
Immunity testing is a requirement of most test standards. There are a few exemptions to this which include very simple products (some children's toys), EMC benign products including products such as induction motors or equipment which is so simple there is no possibility of malfunction being an issue (e.g incandescent luminares)
Regulatory Testing
EMC immunity testingEuropean EMC immunity test standards (which are based on an International equivalent) have been established to provide a legal presumption of conformity to the immunity requirements of the directive when complied with. TRaC has developed a wide ranging capability in EMC immunity testing to meet customer requirements. The testing performed by TRaC has been accredited by UKAS to ISO17025 to ensure that it is of the highest standards.
Immunity test methods are contained within standards referred to as Basic EMC Standards. These standards are referred to by product standards, product family standards, and generic standards for test method and limits.
Below are listed examples of standards that TRaC use for EMC Immunity:
| Country | Standard Ref |
|---|---|
| Europe | EN 55024 (EMC product standard) |
| EN 61000-4 series (basic EMC standard) |
Please contact us for details of the standard applicable to your particular market of interest.
EMC Immunity standards are grouped into two categories:
| Category | Test |
|---|---|
| Immunity to Continuous EMC phenomena | Radiated electromagnetic field immunity |
| Conducted disturbance immunity | |
| Radiated magnetic field immunity | |
| Immunity to Transient phenomena | Immunity to electrostatic discharges |
| Immunity to electrical fast transients | |
| Immunity to ac power supply voltage dips and interruptions | |
| Immunity to lightning surges |
