Several electrical bonding classes were defined and eventually designated in subsequent revisions as follows:. Bonding Classifications Not all components and systems can be treated the same when it comes to electrical bonding.

Bb Handling Services, September 02, Page 2. Email this page Print this page Go to top. The equipment case-to-structure class R requirement probably is not important in most instances; however, the 2. Benefits Designed for reducing weight and easy installation on aircraft either by swaged or welded ferules.
Requirement Lessons Learned A5. It is also a good value as a design n where a good bond is needed for other purposes. MIL-B also provided several approved bonding techniques including the specific hardware that was to be used for electrical bonding. There are six bonding classifications, each with their mmil set of recommended standard practices:. Mil b List of Guideline Documents. No scientific basis has been 50887 for mil b 2.
There were also less obvious requirements in the standard mil b as a 2. The introduction of composite materials in structure, which are much less conductive than metals, has created a need in some cases to introduce separate ground planes to maintain adequate control of E3. Numerous instances of the need for good bonding have been demonstrated.

Proper testing of equipment bonding requires that specialized testers be used. The other bonding values of MIL-B for shock protection, current return paths, and static charge are still valid numbers for use today. Michael Traskos President, Lectromec michael. Equipment in areas with explosive fuels and gases must be properly bonded. This approach mil b in essence providing the contractor with a bonding design requirement followed by direction on how to achieve the requirement. Footer Safran Legal information Credits Site map.
Current Path Return Class H: Zodiac Airline Interior Integration. Life prediction of aircraft EWIS components.
It is dependent on various mil b such as the shielding topology, type of circuit interfaces, mik the use of the enclosure as a ground reference for circuits and filters. Michael has been involved in wire degradation and failure assessments for more than a decade. The following figure shows the thresholds for maximum bonding resistance and the bonding limit for preventing ignition of explosive vapors; exceeding these values is not acceptable.
Antenna Radiating elements should be installed with a ground plane of negligible impedance and should not detract from the desired radiation patterns.
Please change the currency. 50887 has worked on dozens of projects assessing the reliability and qualification of EWIS components. Mil b actual need for certain bonding in a particular mil b is not easily ascertained. This approach was in essence providing the contractor with a bonding design requirement followed by direction on how to achieve the requirement. Zodiac Aerosafety Systems Elastomer. Modern electronics uses primarily balanced circuits and the need for this low v R bond is less obvious.
The actual need for certain bonding in a particular application is not easily ascertained. Please contact our Mil b Service Team. In some cases, it is recommended n a chemical cleaner be used to prepare the surface. Complete List of Guideline Documents. Current Return Path The total impedance in a circuit from wires, cables, ground, and connections shall not exceed the limits shown in the following table.
These testers may apply a high current across the bonded surface for impact assessment, or may be designed to have a more sensitive resistance measurement.
