What Is Automotive Grade

The term “Automotive Grade” is used to describe parts that are up to par with the standards set by the automotive industry. Standards from the AEC-Q series are accepted worldwide as the benchmark for verifying the quality of automotive parts. The American Automotive Electronics Council is abbreviated AEC. GM, Ford, and Chrysler founded it to develop industry-wide standards for components certification and quality management. Q stands for Qualification, and AEC-Q is the AEC-managed vehicle regulation.

A similar benchmark for testing individual parts. The results of the tests are the equivalent of a thorough “physical examination report” for the parts being tested. The Automotive Electronics Council Q (AEC-Q) standard is designed to qualify semiconductor components, such as chips, passive components, and individual semiconductors used in automobiles. As with equipment, test standards vary depending on the evaluation performed.

Necessity of Automotive Grade

Grading helps auction buyers choose cars. The grade helps purchasers understand the vehicle’s overall condition. In general, this information will assist you in deciding how much money you need to spend to make the automobile ready for trade sales. The ratings vary from 2 to 6, although 5 to 3 is usual in most auction houses.

The car grading scheme is classified into grades 1 to 5. Vehicles in severe accidents or requiring extensive repairs fall into an unclassified category. A device with the AEC-Q100 qualification has been subjected to rigorous testing and has been found to meet or exceed the requirements for quality and reliability set out by the AEC. In AEC-Q100, grades 0, 1, 2, and 3 each represent a different temperature range. Each IC has a different temperature range in which it can function well.

Grade 0: The car doesn’t work. Disconnected, broken, or missing mechanical and bodily components are possible. Due to its poor state, this vehicle should be dismantled or sold for scrap. The ambient operating temperature range for grade 0 is -40°C to +150°C.

Grade 1: In grade 1, there might be SMART repairs needed for the vehicle’s interior and exterior flaws, such as removing minor scratches or dents and replacing a few small pieces. Some of the car’s mechanical components may be missing or inoperable. The car is still useable, but it is getting close to the end of its useful life. The usability of add-ons is questionable. The ambient operating temperature range for grade 0 is -40°C to +125°C.

Grade 2: In grade 2, there might be as many as two more body shop repairs, one big and one minor, needed on top of the Grade 1 work. Larger interior or exterior trim pieces (not including panels) may also need to be replaced. The car’s mechanical issues may make it unsafe to drive. The engine and gearbox may be in bad shape, but repairs are possible. The usability of add-ons is dubious. This vehicle may have worn tires or tires that don’t match. The ambient operating temperature range for grade 0 is -40°C to +105°C.

Grade 3: Normal blemishes and nicks from parking lots, scrapes, chips and tiny broken pieces are to be expected with this car. It could need some moderate conventional body and paint repair or component replacement. Even if the car has been repaired according to the collision repair industry’s requirements for aesthetic or minor accident damage, the frame/structure should still measure following the manufacturer’s stated specifications. Interior components have regular wear and tear and need repair or replacement. The ambient operating temperature range for grade 0 is -40°C to +85°C.

Grade 4: Minor traditional body and paint repairs or paintless dent repairs may be needed, but otherwise, the car is in good shape. The car may have minor bodywork or accident damage that has been professionally repaired. No modifications or repairs have been made to the vehicle’s chassis or structure, so it should conform to manufacturer standards. If a little piece is lost or damaged, it may need to be replaced. The inside has been recently cleaned, has little signs of wear, and doesn’t smell bad.

Grade 5: Very small imperfections on panel surfaces that do not need the traditional body or paint repair characterize the vehicle’s otherwise outstanding condition. It’s possible that some minor, high-quality repairs were made. No screws, bolts, or glass shards are missing or broken, and there are no other obvious flaws.

U Grade – “U” grade tightens the damage band for grade 5 vehicles.

Repairs should be carried out following the procedure outlined below.

PDR – Paintless Dent Removal
Re-evaluating Alloy Wheels
Minor paint patching
Glasses service
Modest trim repair
Touch-in type maintenance.
Modest Collision Repairs (Scratches, Chips & Scuffs)

In the case of a bumper or other body panel, a fresh coat of paint is all that’s needed, so long as you take care of the preparations, prime the surface and paint it.

Intensive Work at the Automotive Body Shop (Dents, holes & Gouging)

Preparation, reshaping, filler, primer, color coat, and lacquer, if required, for a bumper or other body panel that has to be repainted and have filler repairs made.

Applications of Automotive Grade

The automotive grade in the automotive industry guarantees that finished products are error- and malfunction-free. Automobiles are often put through extensive testing procedures to provide the best possible engineering, safety, and comfort for the customer. Also, the automotive grade components provide rigorous testing, higher-quality materials, and built-in safety measures.
