Which of the following notations accepted for use with the SI is preferred for the volume
of a gallon of milk? - correct Answer-3.785 L (1 U.S. gallon)
Carl Sagan, on his television series, might have said "Thank you for spending these
billions and billions of nanoseconds with me." How long a time interval is 1800 billion
ns? Note - use the U.S. definition of billion, e.g. 10^9 - correct Answer-Half an hour

simulated reference temperature? - correct Answer-Thermocouple
Crash dummies used to simulate the effects of adults and children during testing of car
and truck collisions are an example of a - correct Answer-Consensus standard
Electrical sensors used to measure temperature almost always require - correct
Answer-Linearization of the temperature - electrical relationship
, A substitute standard has replaced the usual reference standard and the term "limited
calibration" is used on the UUT. Which of the following explanations would NOT be
expected as an explanation of the limited calibration? - correct Answer-The substitute
was used for a limited time
The most common working standard for dimensional analysis is - correct Answer-The
gage block
Measurement of humidity can be accomplished - correct Answer-With a mirror whose
temperature can be controlled
A laboratory that uses an intrinsic standard may not simply use it without verification,
but must also - correct Answer-Participate in interlaboratory comparisons or proficiency
testing for that parameter
The relationship between the freezing point of water and the triple point of water at
standard atmospheric pressure is - correct Answer-The triple point is warmer
The SI unit used by torque wrenches is - correct Answer-N*m
What ratio of attenuator would be required to reduce a 1.0 mW signal to a 1.0 fW
signal? - correct Answer-1 000 000 000 000 :1
The best reason that the local acceleration of gravity, little g, needs to be known by a
laboratory is because - correct Answer-It can affect many calibration results
When using saturated salt solutions to generate (source) humidity, it is important to
know the - correct Answer-Temperate
A client has submitted a 0 - 250 ft-lb, +- 5% of full scale, torque wrench to a lab for
calibration in the clockwise direction. The lab's 0 - 600 ft-lb, 0.25% of reading, clockwise
and counter-clockwise, electronic calibrator is out of order. The lab also owns a spring-
and-needle torque clockwise calibrator that is working and is in calibration. However, it
is 0 - 1000 ft-lb, 1% of reading 2 ft-lb. Can this calibrator be used instead? - correct
Answer-Yes, it is adequate for this job
Which of the following parameters can be converted to relative humidity using a table or
calculation? - correct Answer-Dew point
ANSI/NCSL Z540.3 requires that calibration procedures shall contain generic
descriptions of the IM&TE and reference standards to be used so that - correct Answer-
The technician has all the required information to make a substitution decision
A certificate of calibration issued by an NMI - correct Answer-May be considered
traceable without further evidence
