CPI CPI Material Selection & Specifications 2 — Questions and Answers
Question 1: A product's SDS (Safety Data Sheet) Section 8 primarily covers which information?
- First aid measures
- Exposure controls and personal protective equipment (Correct answer)
- Firefighting measures
- Accidental release measures
Correct answer: Exposure controls and personal protective equipment
SDS Section 8 covers exposure controls and PPE requirements to protect workers handling the material.
Question 2: What is the purpose of a submittal review in a commercial installation project?
- To document worker hours on site
- To confirm proposed materials and methods meet project specifications before installation (Correct answer)
- To order replacement materials after a defect is found
- To obtain the final certificate of occupancy
Correct answer: To confirm proposed materials and methods meet project specifications before installation
A submittal review verifies that proposed materials, shop drawings, and methods comply with the project specifications prior to installation.
Question 3: Which lumber grade stamp marking indicates a stud-grade Douglas Fir-Larch piece suitable for wall framing?
- MSR 1650
- STUD DF-L (Correct answer)
- Select Structural
- No. 3 Southern Pine
Correct answer: STUD DF-L
A grade stamp reading 'STUD DF-L' identifies a stud-grade Douglas Fir-Larch piece rated for vertical wall framing applications.
Question 4: When a specification calls for ASTM A36 steel, what characteristic does this designation define?
- The steel's color and finish
- Its minimum yield strength and chemical composition (Correct answer)
- The permissible bolt hole diameter
- The required surface preparation method
Correct answer: Its minimum yield strength and chemical composition
ASTM A36 is a standard that defines the minimum yield strength (36,000 psi) and chemical composition of structural carbon steel.
Question 5: A CPI installer is selecting adhesive for bonding two dissimilar substrates. What information is most critical to check first?
- The adhesive's color after curing
- Compatibility with both substrate materials and the service environment (Correct answer)
- The adhesive's country of manufacture
- Whether the adhesive comes in a cartridge or bucket
Correct answer: Compatibility with both substrate materials and the service environment
Adhesive compatibility with both substrates and the service environment (temperature, moisture, chemicals) determines bond success and longevity.
Question 6: What is the primary function of a vapor barrier in a wall or floor installation assembly?
- To provide structural support between framing members
- To retard moisture vapor transmission and protect insulation and structure (Correct answer)
- To reflect radiant heat back into the living space
- To serve as a fire-resistant layer between materials
Correct answer: To retard moisture vapor transmission and protect insulation and structure
A vapor barrier retards the transmission of moisture vapor through the assembly, protecting insulation and structural members from moisture damage.
