EIA 364-28 Vibration Testing of Electrical Connectors
EIA 364-28 vibration testing determines the effects of vibrations that are encountered during the life of connectors and sockets. As a certified environmental compliance testing lab, we realize the importance of vibration testing of electrical connectors. Meeting the environmental EIA 364-28 compliance requirements can be difficult. We understand the challenges and guide companies through the process.
Keystone takes a consultative approach throughout the entire test program. Our proven process helps avoid product launch delays. When products do not meet the requirements, we assist with finding solutions. Furthermore, we provide competitive pricing and we offer volume discounts. Keystone Compliance partners with customers to achieve environmental product compliance.
Summary of EIA Vibration Test Method 364-28 Information
EIA 364-28 vibration testing evaluates the effects of vibration within predominant or random vibration frequency ranges. The EIA 364-28 standard test method also evaluates vibrations within magnitudes that may be encountered during the life of the connector.
The test equipment used consists of a vibration machine capable of either generating sinusoidal or random excitation. Random vibration test equipment will produce random excitation that possesses a normal amplitude distribution. However, the acceleration magnitudes of the peak values are limited to a minimum of three times the sigma limits.
EIA 364-28 compliance test information included in the report consists of the date, time, location and test engineer. Other information in the EIA standard test method includes a sample description, test equipment used, test conditions and values and observations.
EIA 364-28 Compliance Testing Procedures of Connectors and Sockets
Conditions for the connector test specimen include a fixture capable of transmitting vibrations. The test fixture is designed so that resonant vibration in the fixture is minor. The EIA 364-28 test item is also to be mounted rigidly to the test fixture as closely as possible to the normal mounting of the connector. Lastly, the vibration input is monitored on the mounting fixture in the proximity of the support points of the specimen.
The 364-28 test specimen is subjected to a simple harmonic motion. This motion has an amplitude of 0.03 inches. The specimen, while de-energized or operating under specified load conditions, is subjected to the vibration amplitudes of either 0.06 or 10 gravity units. Vibration frequency is applied during the 10 to 55 Hz band of the vibration range.
