The Institute of Electrical and Electronics Engineers Inc. (IEEE) revised IEEE 299 - Standard Method for Measuring the Effectiveness of Electromagnetic Shielding Enclosures - to add shielding effectiveness test procedures for enclosures less than two meters in any linear dimension.
Before this, no generally accepted standard covered testing for small shielded enclosures. The revision also:
- Adds methods for estimating measurement uncertainty for the tests covered by IEEE 299.
- Incorporates new or improved test methods.
- Harmonizes this standard with other standards.
The IEEE also began work on IEEE P299.1 - Standard Method for Measuring the Effectiveness of Electromagnetic Shielding Enclosures - which will extend shielding effectiveness test procedures to enclosures having linear dimensions of 0.1 to 0.75 meters at radio frequencies of up to 18 GHz.
IEEE also reaffirmed the continued use of three existing standards:
