Question 1

Which performance rating system is used to evaluate the durability of upholstery fabrics based on simulated abrasion cycles?

Accepted Answer

Wyzenbeek test

Answer

The Wyzenbeek test measures fabric abrasion resistance by counting the number of double rubs before fabric wear is visible, with 30,000+ double rubs recommended for heavy-duty commercial use.

Question 2

What does the term 'solution-dyed' mean when applied to fabrics and why is it relevant in commercial interior design?

Accepted Answer

The color pigment is added to the fiber before it is extruded, resulting in superior fade and stain resistance

Answer

Solution-dyed fibers have color integrated into the fiber itself during manufacturing, providing exceptional UV, fade, and bleach resistance compared to piece-dyed fabrics.

Question 3

Which certification indicates that a fabric or material meets California Technical Bulletin 117-2013 flammability standards for upholstered furniture?

Accepted Answer

CAL 117

Answer

CAL 117 (California TB 117-2013) is a smolder resistance standard for upholstered furniture cover fabrics widely adopted across the US as the baseline fire safety requirement.

Question 4

What does VOC stand for in interior finish specification, and why does it matter for LEED certification?

Accepted Answer

Volatile Organic Compound; limits indoor air pollutants from paints and adhesives for occupant health

Answer

Volatile Organic Compounds (VOCs) are chemicals emitted from paints, adhesives, and finishes that degrade indoor air quality; specifying low-VOC products is required for LEED IEQ credits.

Question 5

Which flooring specification standard classifies hard surface flooring (tile, stone) for slip resistance using the DCOF (Dynamic Coefficient of Friction) rating?

Accepted Answer

ANSI A137.1

Answer

ANSI A137.1 is the American National Standard for ceramic tile that includes DCOF AcuTest requirements, with a minimum 0.42 DCOF for level interior wet areas.
