IPC-9704 distinguishes between two major stress events:
If you share why you need IPC-9704 (e.g., strain test setup, BGA reliability, or compliance audit), I can help explain the core requirements or point you to legitimate excerpts/public summaries. ipc-9704 pdf
The IPC/JEDEC-9704A standard defines methods for measuring mechanical strain on PCBs during manufacturing to prevent solder joint and laminate failures. A compliant report requires using three-element rosettes, sampling at high frequencies, and plotting peak strain against strain rate against a calculated limit line.

Do not pay for it yet. If you outsource your assembly to a CM, ask them first. Most high-reliability CMs (like Benchmark, Jabil, Flex, or reputable regional shops) already own a corporate license for the entire IPC library. They can:
