1. 1A technician reads STRSW on an OEM repair procedure for joining body panels. Which welding equipment does this abbreviation identify?

   1. A.Squeeze-type resistance spot welderCorrect answer: A
   2. B.Gas metal arc welding equipment
   3. C.Gas tungsten arc welding equipment
   4. D.Oxy-fuel welding and cutting equipment

   Explanation: The standard lists a "squeeze-type resistance spot welder (STRSW)". The abbreviation in the repair procedure therefore identifies that equipment; gas metal arc and gas tungsten arc equipment use different designations.

2. 2A steel service part of 590 MPa is being disassembled and installed at a factory seam without creating a new joint. The seam is not laser welded, there is no applicable OEM procedure, attachment method or opposing position statement, and both sides of the joint are accessible. Under I-CAR's best practice, which attachment method is the first choice?

   1. A.Metal inert gas brazing
   2. B.Rivet bonding with adhesive
   3. C.Squeeze-type resistance spot weldingCorrect answer: C
   4. D.Gas metal arc plug welding

   Explanation: I-CAR says: “If no OEM published attachment methods are available, use squeeze-type resistance spot weld (where two-sided access is available), followed by GMA plug welds.” The stated conditions permit the best practice, so resistance spot welding is the first choice.

3. 3During an adhesive repair on an olefin bumper cover, the adhesion promoter has been applied too heavily and the surface looks glossy. According to I-CAR, which sequence corrects the application?

   1. A.Re-sand, allow to dry, and reapply promoter
   2. B.Allow to dry, re-sand, and reapply promoterCorrect answer: B
   3. C.Allow to dry, reapply promoter, and re-sand
   4. D.Reapply promoter, allow to dry, and re-sand

   Explanation: I-CAR advises: “If the surface is glossy, allow it to dry, re-sand the affected area, and reapply the adhesion promoter.” The promoter should be reapplied after the excess has dried and the area has been re-sanded.

4. 4After a collision repair, a technician is reviewing electronic stability-control data. Which signal represents the vehicle's rotation about its vertical axis?

   1. A.Roll rate
   2. B.Wheel rotation rate
   3. C.Yaw rateCorrect answer: C
   4. D.Pitch rate

   Explanation: Bosch explains that “yaw-rate sensors measure vehicle rotation around its vertical axis”. Thus the yaw-rate signal is the relevant input for rotation around that axis.

5. 5A technician is identifying restraint components after a collision. In the restraint configurations studied by NHTSA, which component takes up shoulder-belt slack without also pretensioning the lap segment?

   1. A.Buckle pretensioner
   2. B.Seat-belt load limiter
   3. C.Anchor pretensioner
   4. D.Retractor pretensionerCorrect answer: D

   Explanation: A NHTSA study says a retractor pretensioner “helped to reduce the slack in the shoulder portion of the belt system.” The study describes anchor pretensioners as reducing lap slack and buckle pretensioners as adding tension to both belt segments.

6. 6During a refinish inspection, small crater-like openings appear in the wet coating where contamination has repelled the material. Which defect has developed?

   1. A.Orange peel
   2. B.FisheyesCorrect answer: B
   3. C.Dry spray
   4. D.Solvent popping

   Explanation: I-CAR describes the defect: “Fisheyes are small crater-like openings in the refinish material. It is caused by a contaminated area on a panel that repels refinish materials.” This matches the wet coating and repellent contamination in the scenario.

7. 7A trained technician is preparing the CCOHS-recommended household bleach dilution for a blood-contaminated bleach-compatible, nonporous interior surface. If 10 mL of household bleach is used, how much water is needed for the specified 1:100 solution?

   1. A.1,990 mL
   2. B.90 mL
   3. C.490 mL
   4. D.990 mLCorrect answer: D

   Explanation: CCOHS specifies a “1:100 solution of household bleach (that is, dilute 1 part bleach with 99 parts water)”. Therefore 10 mL of bleach × 99 = 990 mL of water, yielding 1,000 mL total. The other choices produce approximately 1:10, 1:50 and 1:200 total dilutions, respectively.

8. 8A technician is spraying an isocyanate-containing coating. According to CCOHS guidance, which respiratory protection should the technician use?

   1. A.A full-face cartridge respirator
   2. B.A half-face cartridge respirator
   3. C.An air-supplied respiratorCorrect answer: C
   4. D.A powered air-purifying respirator

   Explanation: CCOHS states that breakthrough cannot be detected for isocyanates and advises technicians to “always use an air-supplied respirator when working with isocyanates.”

9. 9A replacement panel has bare metal on the pinchweld where stationary glass will be bonded. Following I-CAR's preparation guidance, which primer should the technician apply to that bare metal?

   1. A.The adhesive maker's bare-metal body primerCorrect answer: A
   2. B.The adhesive maker's glass adhesion primer
   3. C.The refinish maker's self-etch primer
   4. D.The refinish maker's high-build primer

   Explanation: I-CAR states: “Bare metal areas on the new pinchweld require application of the adhesive maker's bare metal body primer.” The specified body primer prepares the exposed pinchweld for bonding.

10. 10A technician is identifying the construction of a laminated movable side window before replacement. According to Pilkington's glazing guide, which material is typically used as the interlayer between the glass plies?

    1. A.Thermoplastic polyurethane
    2. B.Ionomer resin
    3. C.Polyvinyl butyralCorrect answer: C
    4. D.Ethylene-vinyl acetate

    Explanation: Pilkington describes lamination as glass plies bonded by “a special interlayer, typically made from polyvinyl butyral (PVB).” This describes the construction of the laminated sidelight in the question.
