quizzes Flashcards
You on a job and observe the coating is being applied in an unacceptable manner. As the inspector you should
- report to the contractor’s supervisor
- report to the owner’s representative
Which standard gives guidelines for how many DFT measurements should be taken in a given area?
ISO 19840
A pre-job conference should be held
After bids have been submitted and contracts signed
Which of the following are goals of a pre-job conference?
- review and discuss the scope of work
- discuss lines of communication between parties
- discuss and clarify inspector’s responsibilities and authority
What is one of the inspector’s roles at a pre-job conference?
Clarify reporting requirements
According to ASTM D 4417 Method B - 2014, when taking measurements using a profile gauge, at each location you should make
ten (10) readings per location, record the maximum value. Determine mean (average) for all maximum values as the reported profile.
Daily reports or weekly reports should be written in
pen
inspection records may be used to
- help in resolving legal or arbitration disputes
- assist owners in the evaluation of the applicator performance
- asset owners in the evaluation of the inspector’s performance
- determine total cost of the project
a typical daily report should include which of the following? select all that apply.
- description of manpower and equipment used by contractor
- explanation of work stoppages
- list of environmental conditions
The inspector’s log book is a personal chronicle of what happened on a daily basis and is usually
retained by the inspector
generally speaking, on a typical coating project overall safety is the responsibility of
a certified safety professional
when applying coatings, generally high relative humidity
slows solvent evaporation
which is an advantage of airless spray compared to conventional air spray?
faster production rate
You arrive to inspect a bridge repainting project where the containment (enclosure) has already been erected but dehumidification is not being used. What inspection challenges do you expect specific to working inside the containment? (select all that apply)
- illumination
- control of temperature and humidity
improper atomization of the coating may cause which of the following? (select all that apply)
- uneven DFT
- dry spray
- overspray
high viscosity due to low temperature should be corrected by
- adding extra thinner
- heating the coating
SSPC Technology Guide No. 12 states coating inspection requires a minimum of which of the following?
50 foot candles (538 lumens)
one major advantage of conventional spray is
application control
When using a wet film thickness (WFT) comb/gauge, the measurement should be taken
immediately after the coating is applied
when reporting the welt film thickness from a wet film thickness comb/gauge (WFT) you report
the last tooth that has coating on it
solvent borne inorganic zinc primer is being applied with airless spray to a complex bridge with difficult access for application. The contractor is having difficulty with high DFT resulting in mkudcracking. What application method might be a good alternative?
Conventional spray
An advantage of magnetic pull-off DFT (Banana) gauge is that it?
Is intrinsically safe
you myst take a measurement with a dial type magnetic pull-off dry film thickness (DFT) gauge . What is the minimum recommendation distance away from am edge that you can reliably take a measurement?
2.5 cm (1 inch)
The testing procedure for water soluble ferrous salts is
Potassium Ferricyanide Test
