This practice establishes procedures for the investigation and evaluation of a physical component failure. The framework and methodology outlined is not exhaustive, as evaluation of complex component failures often requires unique and/or highly specialized analytical and investigative techniques. Each of the outlined elements of the practice may not be required or possible for each component.

1.1 This standard practice for the engineering investigation and analysis of component failures covers the collection and analysis of all information and physical evidence pertaining to the failure or perceived failure of a specific component. The data and physical evidence includes but are not limited to background information regarding the design (if available), fabrication and expected service conditions of the component, evidence pertaining to the actual service history of the component, and physical evidence relating to the component failure. The nature of the use of the particular component is immaterial with respect to this standard. This standard does not apply to software.

1.2 For the purpose of collecting and generating data, all values will be used with SI (English) units.

This standard may involve hazardous substances and objects, operations, and equipment. 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 and health practices and determine the applicability of regulatory limitations prior to use.
