Questions & Correct Answers | Pass IICRC
Certification with Confidence | A+ Graded
SECTION 1: PRE-INSPECTION & CARPET IDENTIFICATION
Q1: A technician performs a burn test on a carpet fiber sample. The fiber melts, burns with a
chemical smell, and leaves a hard black bead. What type of fiber is this most likely to be?
A. Wool
B. Nylon
C. Polyester. [CORRECT]
D. Cotton
Correct Answer: C
Rationale: Polyester is a synthetic fiber that melts and burns with a chemical (sweet) odor,
leaving a hard bead. Wool (A) smells like burning hair and leaves a crushable ash. Nylon (B)
also melts but is typically slower to ignite and leaves a hard, grayish bead; the chemical smell is
more characteristic of polyester. Cotton (D) burns quickly with a paper odor and leaves fine gray
ash.
Q2: During pre-inspection, a technician observes a carpet with tightly looped, level pile
construction. The backing appears to be woven jute, and the face yarn has a wool-like
appearance but feels slightly coarse. What carpet type is this?
A. Cut-pile Saxony
B. Berber/Level Loop. [CORRECT]
C. Frieze
D. Cut and Loop
Correct Answer: B
Rationale: Berber or level loop carpets feature tightly looped, level pile construction. The woven
jute backing and wool-like appearance are characteristic of traditional Berber styles, often made
,2
from wool or olefin. Cut-pile Saxony (A) has sheared, upright fibers. Frieze (C) has twisted,
textured cut pile. Cut and Loop (D) combines both pile types for patterning.
Q3: A technician is inspecting a residential carpet and notices distinct bands of light and dark
shading across the width of the room that appear permanent. This is most likely:
A. Soil filtration
B. Pile reversal/shading. [CORRECT]
C. UV fading
D. Worn traffic lanes
Correct Answer: B
Rationale: Pile reversal (shading) occurs when carpet pile direction changes due to
manufacturing or installation, creating permanent light/dark bands as light reflects differently off
bent fibers. Soil filtration (A) occurs near walls/under doors from airborne particles. UV fading
(C) is typically more uniform or window-related. Worn traffic lanes (D) show fiber damage, not
directional shading.
Q4: Which fiber type is MOST resistant to acid dye stains such as Kool-Aid, fruit juices, and
wine?
A. Nylon 6,6
B. Wool
C. Solution-dyed Olefin. [CORRECT]
D. Silk
Correct Answer: C
Rationale: Solution-dyed olefin has color built into the fiber during manufacturing, making it
extremely resistant to acid dyes since there are no dye sites for stains to attach. Nylon (A) and
wool (B) are both susceptible to acid dyes. Silk (D) is highly absorbent and easily stained by
acids.
Q5: A technician performs a chemical test using formic acid on a carpet fiber. The fiber dissolves
completely. This indicates the fiber is:
A. Nylon
B. Polyester
C. Wool. [CORRECT]
D. Olefin
,3
Correct Answer: C
Rationale: Wool is a protein fiber that dissolves in formic acid due to its chemical composition.
Nylon (A) resists formic acid. Polyester (B) and olefin (D) are synthetic fibers unaffected by
formic acid. This test distinguishes protein fibers from synthetics.
Q6: During customer communication, which of the following is NOT required per IICRC
standards before beginning cleaning services?
A. Identifying pre-existing damage
B. Explaining cleaning limitations
C. Guaranteeing complete stain removal. [CORRECT]
D. Obtaining signed authorization
Correct Answer: C
Rationale: IICRC standards require technicians to identify pre-existing damage (A), explain
limitations (B), and obtain authorization (D), but guaranteeing complete stain removal (C) is
prohibited as it constitutes unrealistic promises. Some stains may be permanent due to fiber
damage, previous cleaning attempts, or chemical reactions.
Q7: A carpet shows distinct rectangular furniture marks that appear lighter than surrounding
areas. This is most likely:
A. Permanent fiber damage
B. Bleach spots from cleaning chemicals
C. UV fading protected by furniture. [CORRECT]
D. Dye transfer from furniture
Correct Answer: C
Rationale: Furniture blocks UV light, protecting carpet beneath while surrounding areas fade.
When moved, protected areas appear lighter. Permanent damage (A) shows fiber deterioration.
Bleach spots (B) typically have irregular edges. Dye transfer (D) would make areas darker, not
lighter.
Q8: Which carpet construction type is MOST prone to texture distortion and crushing in traffic
areas?
A. Commercial loop pile
B. Dense cut-pile Saxony. [CORRECT]
, 4
C. Level loop Berber
D. Commercial cut pile
Correct Answer: B
Rationale: Dense cut-pile Saxony has upright fibers that bend and mat under traffic, showing
footprints and vacuum marks. Commercial carpets (A, D) are engineered for resilience. Berber
(C) distributes weight across loops. Saxony's plush construction lacks structural support against
crushing.
Q9: A technician identifies carpet as "PET" during inspection. This abbreviation stands for:
A. Polyethylene Terephthalate. [CORRECT]
B. Polyethylene Tetra-chloride
C. Polyester Ethylene Thread
D. Polymer Enhanced Textile
Correct Answer: A
Rationale: PET (Polyethylene Terephthalate) is the chemical name for polyester carpet fiber.
Understanding fiber chemistry helps technicians select appropriate cleaning agents. PET is
commonly recycled from plastic bottles into carpet fiber, making it environmentally significant.
Q10: During pre-inspection, a technician finds carpet installed over a damp concrete slab with
no vapor barrier. What potential issue should be documented?
A. Color bleeding risk
B. Browning and microbial growth potential. [CORRECT]
C. Static electricity buildup
D. Rapid drying advantage
Correct Answer: B
Rationale: Moisture from concrete slabs without vapor barriers causes browning (cellulosic
wicking from jute backing) and creates conditions for mold/mildew. This must be documented as
it affects cleaning method selection and liability. Color bleeding (A) relates to dyes, not moisture.
Static (C) occurs in dry conditions. Damp subfloor slows, not speeds, drying (D).
Q11: Which fiber has the highest specific gravity (density) and will sink in water?
A. Nylon (1.14)
B. Polyester (1.38)
