»Test Chambers for Telcordia (Bellcore) Standard Reliability Testing

Telcordia* Generic Requirements for establishing reliability in telecommunications equipment require the use of environmental testing. Envirotronics is a leading manufacturer of the temperature and humidity test equipment needed to perform the required tests.

We would be pleased to answer any of your questions about our chambers and testing to the Telcordia Generic Requirements. If you need a copy of the specifications for Telcordia Standard Reliability Testing, they can be purchased from Telcordia.

In an effort to help simplify the process of selecting the proper environmental test chamber for your test requirements, we have constructed a simple reference chart. Select your standard from the following list and the reference chart will indicate the Envirotronics Test Chamber Series that we recommend. You will also be provided with a link to the web page that describes that particular chamber.

In the event that your browsing through our chart does not answer your questions. Contact us at 616-554-5020 or email ›sales@envirotronics.com.
