EIA-364-17 Standard Temperature Life Compliance Testing

EIA-364-17 determines the ability of electrical connectors and sockets to withstand elevated temperatures. As an EIA certified environmental test lab, we realize the importance of EIA-364 temperature life testing. Meeting the environmental EIA compliance requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone’s proven process helps avoid product launch delays. We provide comprehensive reports shortly after completion of the environmental standard test. Our certified engineers take pride in helping customers achieve their environmental product certifications. Keystone Compliance provides accurate test reports that are delivered quickly. Furthermore when products do not meet the requirements, we assist with finding solutions.

Summary of EIA Temperature Life Test Method 364-17

As mentioned above, this EIA-364-17 temperature standard establishes procedures to determine the ability of an electrical connector and sockets to resist elevated temperatures with or without electrical loading.

The EIA lab procedure for elevated temperature is performed at an ambient pressure. High altitude and space vacuum applications may require testing at reduced pressure. This will be determined by conditions stated within this EIA-364 test standard.

Scope of EIA-364-17 Elevated Temperature Testing

A suitable air circulating chamber and equipment is used. This equipment must maintain, monitor, and record the test temperature to the tolerance and for the duration specified. Furthermore, the specimen must be fully assembled, mated with the specific number of contacts.

Without electrical load: Unless otherwise specified, the specimen, test boards, wires, and fixtures are normally positioned in the chamber. This is done so that there will be no restriction of airflow.

With electrical load: Unless otherwise specified, the specimen will have the same size contacts wired in a series circuit. The specimen must also be suitably fitted with temperature sensing devices. The devices may be wired and/or mounted. Lastly, the chamber temperature measurements are made in a manner that will indicate the connector exposure temperature. On the other hand, measurements should not indicate chamber temperature source.

EIA-364-17 Lab Testing Procedures

There are three different testing methods within this EIA standard.

Method A: Without Electrical Load –  The connector specimen is subjected to specific chamber temperatures for the test condition number and test duration

Method B: With Electrical Load for Connectors – The test specimen rated current is applied until stabilization is reached. The chamber temperature is then increased until the specified test temperature is reached. Lastly, the chamber temperature is recorded and maintained for a specified period.

Method C: With Electrical Load – For this EIA-364 procedure, the specimen is placed in the test chamber. The chamber is stabilized at a connector exposure temperature and tolerance prior to use. A dc current is then applied. This is done until the maximum connector internal temperature is reached. The dc current must not be exceeded, nor should the temperature rating of the test specimen be exceeded. If the rated test current does not result in the maximum internal temperature to be exceeded, the chamber is increased until maximum temperature is attained.

EIA-364-17 Elevated Temperature Testing Conditions

At the end of the test, specimen are examined for any of the following:

  • Changes in dimension
  • Hardening or softening of dielectric materials
  • Opening of seals
  • Cracking, crazing or delamination of components
  • Fusing or seizure of mating connectors or components
  • Leakage of potting materials.

The EIA-364-17 report includes specific or general information that has been conducted throughout the test. Specific information consists of location of temperature sensing devices, specimen description, number of specimens tested and much more. General information within the test procedure consists of the time, location, date and specific test engineer.

Keystone Compliance Provides Expert EIA Lab Testing

In addition to environmental compliance testing, Keystone has a full scope of expertise including solar radiation, rain, pyroshock, and immersion. Our team strives to give our customers more time and energy on product development instead of testing. Keystone has a full lab of test equipment which permits us to provide short lead times on scheduling.
