Developed by the Society of Automotive Engineers (SAE), the SAE ARP 1705 standard provides a test method for reliably and repeatedly measuring the radio frequency (RF) shielding properties of electromagnetic interference (EMI) seal materials and EMI seals against various joint surfaces. This test method is also used to test the reliability of sealed joint combinations after exposure to harsh environments.
Electromagnetic interference (EMI) occurs when electromagnetic energy from an external source affects an electrical system. These interruptions can be large enough to cause minor interruptions to serious damage. Electromagnetic compatibility (EMC) means that a device has electromagnetic shielding that prevents it from being affected by energy waves in the environment.
Electromagnetic energy is energy expressed in waves, it is ubiquitous and comes in many forms. Each type of energy has a different use, frequency range and wavelength. For example, radio waves are generally used in voice communication, data transmission and radio broadcasting. The frequency range is from 3 Kilohertz to 300 Gigahertz. The wavelength is 10 millimeters or longer.
Electromagnetic shielding is a shield that covers electronics to prevent electromagnetic interference. It is also sometimes referred to as a radiation shield. Electromagnetic interference protection, all electromagnetic interference covers types. RF shielding and magnetic shielding are two subtypes of electromagnetic interference shielding.
RF shielding is aimed at blocking radio frequency electromagnetic radiation. Shields that are effective at blocking RF waves and other wave types are sometimes called EMI/RFI (electromagnetic interference / electric and magnetic field) shields. Magnetic interference must be avoided, otherwise the operation of other magnetic devices may be adversely affected. Some shields combine conductive and magnetic media to prevent interference from both electromagnetic interference and magnetism.
Our organization also provides coaxial testing services to measure the RF shielding properties of EMI gasket materials within the scope of SAE ARP 1705 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
