If you are just looking to perform calculations rather than read the physical document, many reliability engineering software suites (such as ALDS RAM Commander ) have built-in Telcordia SR-332 calculators and modules that automate these exact formulas. Moving Forward with Your Reliability Goals
Telcordia SR-332, titled "Reliability Prediction Procedure for Electronic Equipment," provides mathematical models to estimate the Mean Time Between Failures (MTBF) and Failure Rate (FIT) of electronic components and units.
Telcordia SR-332, titled "Reliability Prediction Procedure for Electronic Equipment," provides mathematical models to estimate the hardware failure rate (measured in FITs, or Failures in Time per billion hours) and MTBF of electronic components and assemblies.

Complete Guide to Telcordia SR-332 Issue 3: Reliability Prediction Procedure for Electronic Equipment
Significantly, calculations for standard deviation and upper confidence bounds are available in Issues 2 and 3 only (these were not included in earlier or later versions). This means Issue 3 offers a level of statistical rigor that some other issues do not provide. telcordia sr332 issue 3 pdf full
Marcus sighed, stopping before a heavy door. He swiped a badge and typed a code. "SR-332 is the standard for reliability prediction for electronic equipment. It’s the law of the land for anyone who remembers the Bellcore days. Issue 3... that was a good standard. Refined the environmental stress factors."
Issue 3 introduced several critical updates to reflect 21st-century technological shifts:
Engineers frequently search for a version to obtain the precise formulas, base failure rates, and environmental factors required for hardware design compliance. Because this technical document is heavily protected by copyright and intellectual property laws, finding an open-access full copy requires navigating proprietary licensing restrictions or utilizing approved engineering software tools.
