IPC-J-STD-020 is about Classification, I think you need IPC-J-STD-033 - "Handling, Packing, Shipping and use of Moisture/Reflow Sensitive Devices
Also avaible on JEDEC's website

Popcorning and delamination of plastic IC packages in reflow assembly is
covered by an IPC/JEDEC standard, IPC/JEDEC J-STD-020C, "Moisture/Reflow
Sensitivity Classification for Nonhermetic Solid State Surface Mount
Devices".  This standard is available free on JEDEC's website.
