SUCCESS
The Inspector's checklist for surface preparation should include: -
correct answer -ambient conditions, conditions of substrate, pre-blast
surface cleanliness, shot/grit size selection, shot/grit cleanliness,
abrasive blasting equipment, surface profile, surface cleanliness after
abrasive blasting, operator qualifications, safety
Abrasive media types include: - correct answer -shot & grit (metallic),
crushed slag, ceramic grit, silica sand, garnet, agricultural abrasives,
specialty abrasives
Abrasive media typically used for recycling include: - correct answer -
steel shot, steel grit
List the pressure ranges that categorize - correct answer -low pressure
water cleaning: <34 MPa (5,000 psi), high-pressure water cleaning: 34
to 70 MPa (5,000 to 10,000 psi), High-Pressure water jetting: 70 to 210
,MPa (10,000 to 30,000 psi), Ultrahigh=Pressure water jetting: >210 MPa
(30,000 psi)
Three types of Water-Blasting include: - correct answer -Comparator
and coupons, replica tape, digital surface profile gauge
Types of soluble salt contamination include: - correct answer -chlorides,
sulfates, nitrates
If inspection is to be effective with regards to soluble salts, the
specification should very clearly state: - correct answer -limits to be
accepted, specific salts to be limited, test method to be used, frequency
of testing, locations in which tests should be administered
Test for soluble salts include: - correct answer -bresle patch, sleeve test,
soluble salt meters, conductivity meters
, Depth of surface profile can be evaluated by several methods: - correct
answer -ISO Comparator, replica tape, digital profile gauge
The ISO Comparator grades may be recorded: - correct answer -Finer-
than-fine grade, fine grade, medium grade, coarse grade, coarser than
coarse grade
The two types of replica tape are commonly used: - correct answer -
Coarse - for 20 to 64um (0.8 to 2.5 mils), X Coarse - for 38 to 115 um
(1.5 to 4.5 mils)
List the standards for using the Replica tape: - correct answer -ASTM D
4417 Method C, NACE SP 0287-2202
When using Replica tape common errors include: - correct answer -
variation in point-to-point profile over the surface being tested, the
presence of particles of dirt on either the replica tape or gauge, gauge
accuracy, the rubbing or burnishing technique
