T/CRRA 0212-2018 The classification and grading standard for used automotive parts, including generators

Scope

Scope: This standard specifies the classification and grading of generators from scrapped vehicles, as well as their labeling and packaging requirements and storage requirements. This standard applies to the classification and grading of reusable generator parts from scrapped vehicles. This standard applies to parts remanufacturing enterprises, repair enterprises, and recycling enterprises. Main technical content: The objects of the classification and grading of reusable generator parts are complete generator assemblies disassembled from scrapped vehicles. According to the requirements of T/CRRA 0202 and T/CRRA 0203, reusable generator parts can be classified and graded into first-level reusable generator parts, second-level reusable generator parts, and third-level reusable generator parts. The classification and grading of reusable generator parts includes the stages of recovery, disassembly and cleaning, inspection and evaluation after disassembly and cleaning, and labeling and tagging. Recovery stage: Ensure that the generators from scrapped vehicles are on the engine, with no obvious damage to the appearance, and accurately record the relevant information on the nameplates of reusable generator parts. Disassembly and cleaning stage: Implement in accordance with the requirements of T/CRRA 0203 clauses 5.2 and 5.3, and may refer to GB/T 28672 clause 4.3. During the disassembly and cleaning process, the integrity of generator components should be maintained, and no damage to their internal structures and devices should be caused. Inspection and evaluation stage: Implement in accordance with T/CRRA 0203 clauses 5.4 and 5.5 and this standard clauses 5.1 and 5.2. Labeling and tagging stage: The production and use of labels and tags for reusable generator parts should be in accordance with T/CRRA 0204 and this standard clause 8.
