IICL Dry Van Ultimate Exam
**Question 1.** Which of the following items must appear on a CSC plate according to the Convention
for Safe Containers?
A) Owner’s telephone number
B) Manufacturing date of the container
C) Maximum payload capacity in kilograms
D) Type of cargo most frequently carried
Answer: B
Explanation: The CSC plate is required to show the manufacturing date, along with the container’s
identification number, maximum gross weight, and other safety-related data. The manufacturing date is
mandatory for tracking the container’s age and inspection schedule.
**Question 2.** Under the TIR Convention, which of the following is essential for a container to transit
multiple customs territories without re-inspection?
A) A tamper-evident security seal applied at the origin
B) A GPS tracking device installed on the container
C) A waterproof paint coating on the exterior
D) A load-bearing capacity label on the door
Answer: A
Explanation: The TIR system relies on a single, sealed security tag that remains intact throughout the
journey, allowing the container to move across borders without additional customs checks.
**Question 3.** ISO 6346 specifies the coding system for containers. What does the fourth character in
the ISO owner code represent?
A) The year of manufacture
B) The container’s size class
C) A check digit for error detection
D) The country of registration
Answer: C
, IICL Dry Van Ultimate Exam
Explanation: The fourth character is a check digit calculated from the preceding letters and numbers to
verify the accuracy of the container identification code.
**Question 4.** According to ISO 1496, which test determines a dry-van’s ability to resist vertical loads?
A) Drop test
B) Stack test
C) Torsion test
D) Impact test
Answer: B
Explanation: The stack test simulates the vertical loads a container experiences when stacked, ensuring
the structure can sustain specified weight limits without deformation.
**Question 5.** Which PPE item is specifically required when inspecting the interior of a container that
previously held hazardous chemicals?
A) Hard hat
B) Chemical-resistant gloves
C) Safety harness
D) Ear plugs
Answer: B
Explanation: Chemical-resistant gloves protect the inspector from residues that may remain on interior
surfaces after hazardous cargoes.
**Question 6.** In the anatomy of a dry-van, the component that connects the top rail to the corner
post is called the:
A) Header
B) Crossmember
C) Side rail
D) Bracket
, IICL Dry Van Ultimate Exam
Answer: A
Explanation: The header (front or rear) ties the top rail to the corner posts, providing rigidity to the
container’s longitudinal direction.
**Question 7.** Which of the following wall panel types typically provides the highest impact
resistance?
A) Flat bar panels
B) Corrugated steel panels
C) Aluminum composite panels
D) Fiberglass reinforced panels
Answer: B
Explanation: Corrugated steel panels have a wavy shape that distributes impact forces more effectively
than flat surfaces.
**Question 8.** The purpose of the forklift pocket strap is to:
A) Reinforce the door hinges
B) Prevent the pocket from deformation during lifting
C) Secure cargo to the floor panels
D) Provide a mounting point for the roof vent
Answer: B
Explanation: The strap holds the pocket’s shape, ensuring the pocket does not deform when a forklift
lifts the container by the top.
**Question 9.** Which component of the door assembly is primarily responsible for sealing the
container against weather ingress?
A) Hinge pins
B) Locking bar cam
, IICL Dry Van Ultimate Exam
C) Rubber gasket
D) Door leaf reinforcement
Answer: C
Explanation: The rubber gasket, positioned between the door leaf and the frame, creates a
weather-tight seal that prevents rain and wind from entering.
**Question 10.** When using the “straight-edge” method to assess side panel dents, the maximum
allowable clearance between the straight-edge and the panel is:
A) 2 mm
B) 4 mm
C) 6 mm
D) 8 mm
Answer: B
Explanation: IICL-6 specifies a 4 mm tolerance for dents measured with a straight-edge; anything greater
requires repair.
**Question 11.** The reference string method is employed to measure:
A) Roof panel bowing
B) Door alignment
C) Corner post twist
D) Floor panel thickness
Answer: A
Explanation: A taut string is placed across the roof; the deviation from the string indicates upward or
downward bowing, which is measured against tolerance limits.
**Question 12.** According to IICL-6, the maximum internal cube intrusion allowed on a side panel is:
A) 30 mm
**Question 1.** Which of the following items must appear on a CSC plate according to the Convention
for Safe Containers?
A) Owner’s telephone number
B) Manufacturing date of the container
C) Maximum payload capacity in kilograms
