What is ISO 21494 - Magnetic testing about ?
ISO 21494 specifies magnetic test methods including magnetic field test methods, magnetic moment test methods, magnetization, and demagnetization test methods, and magnetic compensation test methods.
ISO 21494 applies to magnetic tests on several levels:
- Spacecraft-level
- Subsystem-level
- Unit-level
ISO 21494 gives guidelines for conducting magnetic tests both in a zero-magnetic field environment provided by magnetic test facilities and in the presence of the geomagnetic field environment.
Who is ISO 21494 - Magnetic testing for ?
ISO 21494 on magnetic testing is useful for:
- Spacecraft and space products manufacturers
- Aerospace and defence industries
- Design engineers of space products
- Quality control personnel for space products
Why should you use ISO 21494 - Magnetic testing ?
The magnetic tests on Earth-orbiting or interplanetary spacecraft missions with very stringent requirements on magnetic cleanliness are needed to ensure that the spacecraft’s inherent magnetic properties meet the design goals.
ISO 21494 provides magnetic test requirements and methods for measuring and evaluating the magnetic properties of the spacecraft.
The magnetic test methods outlined in ISO 21494 are effective enough for verifying the compliance of magnetic requirements imposed on the spacecraft and for ensuring the success of spacecraft flight missions free of magnetic interference and magnetic contamination due to magnetic materials and induced current-generated magnetic fields of the spacecraft.
