- Scope
This guide references requirements that are intended to control the quality of NDT data. The purpose of this guide, therefore, is not to establish acceptance criteria and therefore approve composite materials or components for aerospace service.
Certain Practices referenced in the guide are written so they can be specified on the engineering drawing, specification, purchase order, or contract, for example, Practice E 1742 (Radiography).
Acceptance Criteria8212;Determination about whether a composite material or component meets acceptance criteria and is suitable for aerospace service must be made by the cognizant engineering organization. When examinations are performed in accordance with the referenced documents in this guide, the engineering drawing, specification, purchase order, or contract shall indicate the acceptance criteria.
Accept/reject criteria shall consist of a listing of the expected kinds of imperfections and the rejection level for each.
The classification of the articles under test into zones for various accept/reject criteria shall be determined from contractual documents.
Rejection of Composite Articles8212;If the type, size, or quantities of defects are found to be outside the allowable limits specified by the drawing, purchase order, or contract, the composite article shall be separated from acceptable articles, appropriately identified as discrepant, and submitted for material review by the cognizant engineering organization, and dispositioned as (1) acceptable as is, (2) subject to further rework or repair to make the materials or component acceptable, or (3) scrapped when required by contractual documents.
Acceptance criteria and interpretation of result shall be defined in requirements documents prior to performing the examination. Advance agreement should be reached between the purchaser and supplier regarding the interpretation of the results of the examinations. All discontinuities having signals that exceed the rejection level as defined by the process requirements documents shall be rejected unless it is determined from the part drawing that the rejectable discontinuities will not remain in the finished part.
Life Cycle Considerations8212;The referenced NDT practices and test methods have demonstrated utility in quality assurance of PMCs during the life cycle of the product. The modern NDT paradigm that has evolved and matured over the last twenty years has been fully demonstrated to provide benefits from the application of NDT during: (a) product and process design and optimization, (b) on-line process control, (c) after manufacture inspection, (d) in-service inspection, (e) and health monitoring.
In-process NDT can be used for feedback process control since all tests are based upon measurements which do not damage the article under test.
The applicability of NDT methods to evaluate PMC materials and components during their life cycle is summarized in Tables 3 and 4.
General Geometry and Size Considerations8212;Part contour, curvature, and surface condition may limit the ability of certain tests to detect imperfections with the desired accuracy.
Reporting8212;Reports and records shall be specified by agreement between purchaser and supplier. It is recommended that any NDT report or archival record contain information, when available, about the material type, method of fabrication, manufacturers name, part n...........
