CHAPTER 4
TEST EQUIPMENT AND SAFETY PROCEDURES
CHAPTER OBJECTIVES
Upon completion of this chapter, you should be able to:
1.
Identify the equipment used in testing retail motor-fuel dispensing systems.
2.
Identify procedures for the use and care of test equipment.
3. Describe the proper steps to perform a liquid-measuring accuracy test using a 5-gallon test measure.
4. Recognize the importance of following proper safety practices and procedures when inspecting and
testing retail motor-fuel dispensing systems in the field.
5. Understand the purpose and procedures for filling out report forms used by your jurisdiction.
Inspection and Test Equipment
The basic equipment required for field examinations of retail motor-fuel dispensing systems includes:
•
accurate linear-measuring device, such as a tape measure,
•
5-gallon calibrated test measure, or calibrated test measure as directed by your jurisdiction,
• metal bucket,
• wide-necked metal funnel (plastic is not recommended, as explained in this chapter),
•
blank inspection report forms,
• NIST Handbook 44 and copies of other procedures and codes used by your jurisdiction,
•
applicable NIST Examination Procedure Outlines,
•
price computation tables or hand-held calculator,
•
security seals and applicator,
•
inspection stickers and tags,
•
fire extinguisher,
•
hand tools (screwdrivers, pliers, etc.), and
• warning flags or cones.

The linear-measuring device is used to check the length of the dispenser discharge hose: maximum lengths are
specified in Handbook 44.
The calibrated test measure is used to test the accuracy of the dispenser's metering device. Procedures for the
care and use of this instrument are described below. Refer to Figure 4-1 for typical 5- and 10- gallon test
measures.
The funnel is used to return test drafts to the storage tank after volumetric tests have been com
