As a petroleum laboratory supervisor, you must observe laboratory technicians to evaluate their testing
procedures and follow-up on corrections of their deficiencies.
PART A - VERIFY THAT THE CORRECT TEST METHOD IS SELECTED IAW
Recommendations. The recommendation for use of a petroleum product is the prime responsibility of
the noncommissioned officer in charge (NCOIC) of a laboratory. The use of a petroleum product is based on
the results of tests performed by technicians assigned to the laboratory. Therefore, it is important to ensure
the correct test method is utilized and all test procedures are strictly followed. Evaluation of a new
technician's laboratory techniques and knowledge of appropriate procedures is essential during the first 90
days on the job, as well as periodically thereafter. During the initial 90-day period, correct techniques can be
implemented and deficiencies eliminated. In addition, periodic checking thereafter will serve as
Reference Materials. To enable 77L30 soldiers to manage this phase of laboratory administration, they
must be thoroughly familiar with the following reference materials:
Military specifications. Each product has its own specification. A specification is a clear, concise, and
accurate description of the technical requirements of a material or product and includes the procedures
for determining when requirements have been met. Specific ASTM or Federal Test Method Standard
(FTMS) are found in section II and section IV of the specification. Minimum and/or maximum test limits
are found in section III of the specification.
ASTM Standards 05.01, 05.02, 05.03, and 05.04. The ASTM contains the majority of test procedures
used by petroleum laboratory technicians. It is published annually in March. The ASTM may be
purchased from the American Society for Testing Materials.
FTMS No. 791. Federal test methods cover those methods adopted for use by federal agencies.
Usually, only the federal test methods without adopted ASTM test standards are included in the
(Military Handbook) MIL-HDBK-200. This handbook provides general instructions and procedures to be
used worldwide by the military services in quality surveillance of government-owned fuels, lubricants,
and related products. Frequently used special test procedures are found in the appendices.
PART B - IDENTIFY DEFICIENCIES IN TEST METHOD PROCEDURES BY
COMPARING THE TECHNICIAN'S PROCEDURE WITH THE TEST METHOD
Testing Errors. It is impossible to list all the errors that may occur when performing various tests since
test methods differ greatly. However, the following list contains the general areas you should watch.
Is the correct ASTM or FTM standard being used as outlined in the specification?
Are all safety procedures being observed?
Is the correct sequence being followed?
Is the glassware correct for the test method?
Is it clean and serviceable?
Was the sample can shaken?
Was the correct amount used?
Was the sample prepared according to the test method?
- Was the sample cooled to a specific temperature range?
- Was the sample heated to a specific temperature range?
- Was the sample filtered?
- Was the sample dehydrated?
