Close valve (1).
Place sample container, furnished with portable test kit, under the valve (1).
Open the valve partially to slowly fill the sample container. Close drain valve when filled.
Properly dispose of waste fuel.
Each TPT is furnished with a petroleum aviation fuel contamination testing kit.
See TM 10-6630-240-12&P or TM 10-6630-218-10 for use of this kit.
Instructions for using the kit are also on a placard attached inside the storage chest.
The kit is capable of testing for particulate contaminants specific gravity (API standard) free water
An extra set of hydrometers in ranges from API Gravity 290 to 810 are supplied with the fuel sampling
assembly. See TM 10-6630-240-12&P or TM 10-6630-218-10 for hydrometer use.
Laboratory facilities are not furnished for a TPT. The following laboratories are normally furnished to the
· Airmobile Petroleum Laboratory (NSN 6640-00-902-9711) On-site portable facility used to analyze
fuel and oil for aircraft.
· Petroleum Base Laboratory (NSN 6640-00-303-4940) On-site portable facility used to analyze fuel
and oil for ground equipment.
Sampling and Test Frequency.
Sampling and test frequency are determined by the service mission and specific operations of the particular TPT. It is
recommended that a specific sampling and test program be set up for each particular TPT. The following are guidelines
to assist in determining the sampling and testing requirements.
The pipeline feeding the TPT may be used for multiple fuel service. When a new
batch of fuel is shipped up the pipeline, the dispatcher will advise the operating
supervision at the TPT of its estimated time of arrival. Between these batches is a
section of co-mingling called the "interface".
Sampling and Testing to Determine Cut. Testing will determine when interface has arrived and passed.
Take samples at sampling assembly (figure 2-19) and test in accordance with portable test kit.
Samples will be taken 30 minutes before the interface is scheduled to arrive and then at decreasing
intervals down to 30 seconds until the change in characteristics indicate the arrival of the interface.
