NCIDQ Materials, Finishes, and Specifications 1 — Questions and Answers
Question 1: Which carpet specification method describes performance requirements without naming a specific product brand?
- Descriptive specification (Correct answer)
- Proprietary specification
- Reference standard specification
- Base bid with alternate specification
Correct answer: Descriptive specification
A descriptive specification defines performance criteria, construction methods, and material properties so any product meeting those standards can be used.
Question 2: What does VOC stand for in interior finish specifications, and why is it regulated?
- Volatile Organic Compound; regulated because it contributes to poor indoor air quality (Correct answer)
- Vinyl Overlay Coating; regulated for flammability
- Visual Opacity Coefficient; regulated for light transmission
- Vapor-Only Content; regulated for moisture control
Correct answer: Volatile Organic Compound; regulated because it contributes to poor indoor air quality
VOCs (Volatile Organic Compounds) are chemicals that off-gas from many finish materials and adhesives, contributing to poor indoor air quality and health risks.
Question 3: Which flooring material is rated by the Coefficient of Friction (COF) for slip resistance?
- Ceramic and porcelain tile (Correct answer)
- Carpet tile only
- Luxury vinyl plank only
- Hardwood flooring only
Correct answer: Ceramic and porcelain tile
Ceramic and porcelain tile are commonly rated by static and dynamic Coefficient of Friction (COF) to ensure adequate slip resistance, especially in wet areas.
Question 4: What does the Wyzenbeek test measure for upholstery fabric?
- Abrasion resistance (durability) (Correct answer)
- Colorfastness to light
- Tensile strength under load
- Flammability in a vertical position
Correct answer: Abrasion resistance (durability)
The Wyzenbeek test measures upholstery fabric abrasion resistance by rubbing a wire mesh back and forth across the fabric and counting double rubs until wear shows.
Question 5: What is the significance of an 'MR Credit' in LEED v4 for material specifications?
- It rewards use of materials with recycled content, regional sourcing, or third-party certification (Correct answer)
- It indicates materials that meet fire code minimums
- It refers to moisture-resistant products in wet areas
- It applies only to mechanical room materials
Correct answer: It rewards use of materials with recycled content, regional sourcing, or third-party certification
LEED v4 Materials & Resources (MR) credits reward selection of products with environmental attributes such as recycled content, bio-based content, or Environmental Product Declarations (EPDs).
Question 6: Which countertop material has the highest resistance to heat, scratches, and chemicals in a laboratory or heavy commercial setting?
- Epoxy resin (Correct answer)
- Laminate (HPDL)
- Quartz composite
- Solid surface (e.g., Corian)
Correct answer: Epoxy resin
Epoxy resin countertops are standard in laboratories because they resist chemicals, heat up to 350°F, and physical abrasion better than other countertop materials.
