IEEE 299.1-2013

IEEE 299.1-2013 is a technical standard for measuring the shielding effectiveness of enclosures and boxes with all dimensions between 0.1 m and 2 m. In the field of fields, waves and electromagnetics, it provides a defined method for evaluating how well a structure limits electromagnetic energy from entering or leaving. This matters when designers, testers, and buyers need consistent results for small to medium enclosures used in sensitive electronic applications.

About IEEE 299.1-2013

This standard addresses a specific measurement problem: how to assess the shielding performance of enclosed or boxed structures within a size range suited to many practical electronic assemblies. IEEE 299.1-2013 supports repeatable testing by describing a common method rather than leaving the approach to ad hoc interpretation. As a result, it is useful for comparing materials, enclosure designs, and fabrication outcomes in a controlled electromagnetic compatibility context.

Where is IEEE 299.1-2013 used?

IEEE 299.1-2013 is typically used where small to medium enclosures must be checked for shielding performance, such as instrument housings, control boxes, communication equipment cabinets, and protective cases for sensitive electronics. It is relevant in laboratory testing, design validation, and procurement review when electromagnetic isolation is important. The standard is especially useful for products that must manage interference, leakage, or susceptibility in fields, waves and electromagnetics work.

Importance in practice

In practice, this standard helps teams apply a consistent measurement method when evaluating shielding effectiveness, which reduces ambiguity in test results and specification claims. IEEE 299.1-2013 supports design control by making it easier to compare enclosures across builds, suppliers, or revisions. It can also improve compliance checking and risk reduction when electromagnetic performance affects reliability, system integrity, or acceptance testing.
