MIL-H-5606 is used when the container has a removable top, and MIL-PRF-5606 is in a sealed container. The PRF specification indicates it is "Super Clean" from the manufacturer, and requires that the can stay sealed. We do can down the PRF material to re-sealable containers, but they have to be listed as MIL-H-5606A material.
