1.1 This practice is intended to be used to assign part grade across the automotive industry. For this standard the term classification was changed to grade to avoid confusion with existing classifications in the automotive industry.

1.2 See Practice F3572 for aviation part classifications and NASA-STD-6030 for spaceflight part classifications.

1.3 This practice is applicable to all AM technologies defined in ISO/ASTM 52900 used in automotive.

1.4 This practice is intended to be used to establish a metric for AM parts in downstream documents.

1.5 This practice is not intended to establish criteria for any downstream processes, but rather to establish a metric that these processes can use.

1.6 The part grade metric could be utilized by the engineering, procurement, non-destructive inspection, testing, qualification, or certification processes used for AM automotive parts.

1.7 The grading scheme in this practice establishes a consistent methodology to define and communicate the consequence of failure associated with AM automotive parts.

1.8 The material or process, or both, in general does not affect the consequence of failure of a part, therefore the grading scheme defined in this document may be used outside AM.

1.9 The user of this standard should not assume regulators’ endorsement of this standard as accepted mean of compliance.

1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
