P-D-680, also known as CID A-A-59601, contains harmful chemicals that adversely affect the environment. Bottom line: P-D-680 is
NOT the same as MIL-PRF-680!
MIL-PRF-680 is better for the environment and user health, while maintaining cleaning performance.
If you’re using P-D-680/CID A-A-59601 in your cleaning processes, STOP!
Use MIL-PRF-680 instead.

Note that when units are updating from P-D-680 to MIL-PRF-680, the solvent type should remain the same. For example, P-D-680 Type I should be replaced by MIL-PRF-680 Type I, and so on.
