MPC
MPC turns up in 2 fields: tribology, logistics. Here is what it means to the people in each one.
MPC in tribology
Membrane patch colorimetry, a test that measures varnish-forming material in turbine and hydraulic oils.
Membrane patch colorimetry: ASTM D7843, in which a conditioned oil sample is mixed with solvent and drawn through a 0.45 micron membrane. A spectrophotometer reads the color of the deposit left on the patch and reports it as a Delta E value. Most labs treat under 15 as normal, 15 to 30 as worth watching, and anything over 30 to 40 as a high varnish potential.
"MPC is 38 on the gas turbine, get the varnish removal skid hooked up before the servos start sticking."
MPC in logistics
Mobile Passport Control is an app that speeds up US customs and immigration for eligible travelers.
Mobile Passport Control (MPC) is an official application created by US Customs and Border Protection that allows eligible travelers to submit their passport and customs declaration information via their smartphone. By transmitting this data before reaching the inspection booth, passengers can use dedicated, faster processing lanes at major airports and cruise ports. It functions similarly to Global Entry but does not require a background check or fee.
"The regular customs line was an hour long, but I used MPC and walked right up to the officer."
