EN 50147 Electromagnetic Shielded Room High-performance Shielding Effectiveness EMC Test Equipment​

Standards & Clauses:

EN50147 “High-performance shielding room shielding effectiveness of the measurement method”
CISPR17 “passive radio interference filter and suppression element suppression characteristics of the measurement method”
CISPR25 “Radio disturbance characteristics of vehicles, boats and internal combustion engines Limits and methods of measurement for the protection of vehicular receivers”
ISO11452-4 “Road vehicles with narrowband emitted electromagnetic energy electronic interference components test method BCI large current injection method”
GB/T 50719-2011 “Electromagnetic shielding room engineering specifications”
GB/T 12190 “Electromagnetic shielding room shielding effectiveness of the measurement method”

Samples and Restrictions:

The electromagnetic shielding room is used to isolate the electromagnetic environment indoors and outdoors to ensure the normal operation of indoor electronic and electrical equipment. Mainly used for conducted emission test, conducted immunity test, EMI discontinuous interference test, etc.

Application:

Electrical appliances and electronic devices, including in-car electronic systems, generate a certain amount of electromagnetic waves at work that may interfere with surrounding equipment or be received by specialized equipment.
The electromagnetic shielding room is used to isolate the electromagnetic environment indoors and outdoors, which can prevent external electromagnetic interference from entering the room to affect the test, and can limit the electromagnetic leakage of indoor high-power high-frequency equipment to prevent the influence to people and equipment around. It is the ideal venue for EMC testing.

Test Principle:

Electromagnetic shielding room is mainly used for automotive electronic conduction emission (CE) test, transient conducted immunity test, bulk current injection method (BCI) test, stripline method test, etc.

Structure:

Power supply: 380V ± 10% 50 / 60Hz
Ambient temperature: 5 °C ~ +40 °C, there should be no high concentration of dust, corrosive gas, flammable and explosive objects
