It mathematically combines the generic data from Method I with real-world data obtained from Highly Accelerated Life Testing (HALT) or Reliability Demonstration Testing (RDT). To execute a calculation using the SR-332 Issue
This article provides a deep dive into SR-332 Issue 3, its methodology, its differences from other standards (like MIL-HDBK-217), and how to effectively use it for your projects.
Because Telcordia (now Ericsson) standards are intellectual property, official access to the full requires a commercial license. Authorized Channels This article provides a deep dive into SR-332
Use the curves and tables in the standard. For example, a capacitor’s (\pi_T) might be 1.2 at 55°C vs. 0.8 at 25°C.
This is the most accurate predictive method. The base failure rate is scaled using precise stress factors:
