FM 10-67-1 APPENDIX E

The sampling coupler must be permanently attached to a fuel probe mounted

downstream from the filter/separator. For the test to be accurate, the sample

must be taken from a moving stream of fuel. The sample should be drawn at a

rate of 600 to 800 mL/minute. When sampling the fuel in a system, ensure the

pump is running and at least one nozzle is open. If sampling the fuel in a filter,

take the sample while recirculating the fuel before operations. Take the

sample using the procedures described below.

Couple the detector pad holder assembly, with the toggle valve closed

(parallel to the line), to the sampling coupler. The detector pad holder

assembly includes plastic tubing, the detector pad holder, toggle valve,

and sampling coupler.

Flush the sampling line immediately before sampling. Put the end of the

plastic tubing in a container that will hold approximately 1 gallon. (Note:

The amount of free water in a sample is very sensitive to the temperature

of a sample. Using bottles or cans for a sample container could result in

errors due to sample temperature or adsorption of water on container

walls.) Open the toggle valve by turning the handle up (perpendicular to

the line). Flush the detector pad assembly by displacing at least 1 liter of
