Selecting and Preparing the Apparatus
Each test method stipulates the type and or composition of the
apparatus to be used in the procedure. This is to ensure that
the procedure is performed to the standard established by the
ASTM/FTM standard. You must verify that the apparatus conforms
to the test method.
Ensure that it is assembled properly and
does not pose a safety hazard. You may be required to show the
technicians the proper way to do this; therefore, you must know
how to do this.
Remember proper handling and setup of the
apparatus will contribute to the successful performance of the
This also impacts on the overall safety and
accuracy of the test results.
Using Proper Techniques and Correct References
The techniques used by the technicians must be the same as those
given in the ASTM/FTM test methods. You must verify this. You
will need to observe the technicians while the procedures are in
progress in order to determine if they are actually using the
You must also ensure that the references
for the test method is present and technicians have access to
them without having to leave the test site.
Your presence and
proximity are essential whenever technicians need you for any
assistance. Onsite help is a crucial element in the attainment
of accurate test results.
Be prepared to assist technicians
while they are performing the procedures.
Performing Independent Calculations
Identify the errors in calculations made by the technicians by
performing your own independent calculations.
Ensure that the
test results are reported according to the method outlined in
Be able to identify the step(s) where the error
occurs and explain to technicians the proper procedures as well
as identify methods to prevent further occurrence of the same
You must foster thoroughness in the way technicians
conduct the day-to-day test procedures.
This helps eliminate
mistakes, develops proficiency, and increases the accuracy of
Communicating the Significance of the Test Method
A proven method of ensuring accuracy and compliance in
laboratory operations is that the supervisor gets involved in
all aspects of the operation.
It is good practice to discuss
