NACE CIP Level 1& 2 Study Guide With Satisfied Solutions
What are the most important characteristics of a good report? - Objective, Accurate, and
... [Show More]
Detailed.
What is the inspector's primary responsibility and what should the inspector not do as it
pertains to the specification. - The Inspector's primary responsibility as the inspector is to
"enforce" specification. The inspector is NOT to make changes to the specification for any
reason.
What type of information could you expect to find on a Product Data Sheet? - Surface
preparation and application information such as recommended level of surface cleanliness,
recommended application methods and equipment such as tip sizes. Also, environmental
parameters for application such as max and min temperatures, curing times, recoat
windows.
What type of information could you expect to find on a Safety Data Sheet? - Health, safety
and environmental. The PPE required. Physical characteristics. Emergency responder
information.
Define Corrosion - The deterioration of a substance, usually a metal from a reaction with its
environment
What is passivation? - A layer of oxides formed on the surface of a metal that provides
corrosion protection.
What is an example of passivation? - Stainless Steel
What are the elements of a corrosion cell? - Anode, Cathode, Metallic Pathway, Electrolyte
Describe what happens at the anode. - The metal dissolves into the electrolyte
What is the function of the electrolyte? - Allows the passage of ions to connect the corrosion
cell
What is the function of the metallic pathway? - Allows the flow of electrons to connect the
corrosion cell
What is the galvanic series? - A listing of metals in order of reactivity (more or less noble)
in seawater at 25 C
The general rules of galvanic corrosion are: - The less noble (or more reactive) metal when
connected to a more noble (or less reactive metal) will corrode preferentially
Name the five most important factors that affect the rate of corrosion. - Humidity, oxygen,
chemical salts, pollutants, temperature
General corrosion is: - Results in a relatively uniform loss of material over the entire
surface, Results in a general thinning of the affected surface, Relatively easy to inspect,
Does not casue catastrophic failures
Localized corrosion is: - Typically pitting and crevice corrosion. It is typically of the most
concern as damage is concentrated and loss of integrity or structural failure can result.
List some of the common tools/methods used for corrosion control. - Design, Inhibitors,
Material Selection, Cathodic Protection, Protective Coatings, Splash Zone Systems,
Alteration of the Environment
How does NACE define the inspector's role? - The inspector's role is that of a quality control
technician responsible for observing and reporting conformance or deviation from the
project specification.
What is the inspector's responsibility when it comes to safety on the project? - Safety
enforcement is not the responsibility of the inspector; however, it is his/her responsibility
to report any issues that may affect the project.
Name some tests that may need to be conducted during surface preparation and coating
operations. - Temperature, Relative Humidity, Dew Point, Anchor Profile, Surface Cleanliness
Name some of the documentation/reports that may be required to be maintained on a
coatings project. - Daily/weekly summary, material usage reports, manpower and
equipment, non conformance, and conformance
Explain the difference between Quality Assurance (QA) and Quality Control (QC). - Quality
Assurance - Any systematic process of checking to see whether a product or service being
developed is meeting specs.
Quality Control - A procedure or set of procedures intended to ensure that a manufactured
product or performed service adheres to a defined set of quality criteria or meets the
requirements of the client or customer
Identify some of the defects that can be caused by incorrect application temperatures. -
Failure to cure, too rapid solvent evaporation, poor film formation
Describe relative humidity. - The amount of moisture in the air compared to saturation level
What is the dew point temperature? - The temperature at which moisture will begin to form
on a steel surface.
Name some of the effects wind may have on a coatings project. - blowing abrasives, causing
excessive drift or overspray, accelerating solvent evaporation, contributing to the formation
of dry spray
What are some of the common errors when using an electronic hygrometer? - Failure to
acclimate the instrument to the environment with adequate time.
Explain the process for use of the sling psychrometer. - Make sure the wick is wet and clean,
continue to "sling" until 3 consecutive readings are achieved [Show Less]
