To acquire the official, full SR-332 Issue 3 (or the most current Issue 4) document, you should visit the Ericsson Telecom Information Center or look for it through authorized technical document distributors such as .
The standard represents a mature, industry-endorsed approach to electronic reliability prediction. Developed with input from a cross-section of major industrial companies, it offers a high level of credibility free from individual supplier bias.

), quantified in , which equals 1 failure per 10910 to the nineth power (one billion) operating hours.
Used when a manufacturer has performed accelerated life testing (ALT) or burn-in testing on components or modules.
The standard includes clarified definitions regarding operating temperatures and component names, reducing ambiguity in calculations. To acquire the official, full SR-332 Issue 3
Executing a professional reliability prediction using the SR-332 standard follows a structured engineering workflow:
The current rights holder for Telcordia documents is (which acquired Telcordia in 2012). The historical contact point for the standard was the Telcordia Customer Service Center. However, Ericsson has since integrated the SR-332 standard into its broader suite of documents.
Inclusion of brand new baseline data for fiber optic transceivers, hard drives, and ferrite beads. ): The inherent failure rate of the component
Telcordia SR-332 Issue 3 is a prominent, copyrighted standard ("Reliability Prediction Procedure for Electronic Equipment") defining methodologies for calculating Failure In Time (FIT) and MTBF, often serving as a commercial alternative to MIL-HDBK-217. Published in 2011, it introduced three methods—black box, lab data, and field data integration—to calculate hardware reliability, with Issue 4 now available as a successor. To review the official documentation, visit Ericsson's telecom-info site .
For organizations that built their reliability databases and internal processes around the 2011 version, Issue 3 remains the baseline standard of record. Furthermore, many contracts and customer specifications still explicitly call out "Telcordia SR-332 Issue 3" by name as the required prediction method.
Aggregate the failure rates to find the overall system FIT (Failures in Time per 10910 to the nineth power hours) and invert it to calculate MTBF in hours.
