APPENDIX A: LEVEL I - MATERIAL QUALITY ASSURANCE REQUIREMENTS
A 1.0 General A 1.1 The requirements listed below shall be used for Level I material when identified in the purchase orderor on Drawings, in conjunction with the requirements in the body of this specification, and quality assurance requirements, as specified by the applicable purchase order. When more stringent material quality assurance requirements are provided in the Purchaser’s purchase order or component specification, they shall take precedence. A 1.2 Objective Quality Evidence (OQE) will be required for all material (separately furnished or within assemblies) identified as “Level I” in the list of materials (i.e. EBOM – Engineering Bill Of Materials) in the basic design document or purchase order. A 1.3 The manner in which required OQE is developed by the supplier shall be controlled by clear, complete and current procedure(s). The OQE for the actual item being shipped shall be representative of the individual heat, batch, or lot as defined in the applicable specification and shall be in compliance with the invoked acceptance criteria. However, for continuous melt or continuous pour processes, the OQE shall be representative of the time period (as determined by the invoked specifications) during which the material was poured. A 1.4 The supplier must identify by procedure where in its process the Level I controls of this Appendix are invoked in their facility. A 2.0 Quality System Flowdown Requirements A 2.1 Suppliers of Level I material are required to have an effective QMS which assures their sub-tier suppliers maintain effective systems for controlling Level I material, including traceability to OQE in accordance with the requirements of this document. Any special quality provisions, along with the applicable specifications and/or drawing requirements, shall be included in the purchase order to the sub-tier supplier if the primary supplier invokes Level I requirements on their sub-tier supplier. A 3.0 Material Control and Identification A 3.1 Procurement Control a) The Level I supplier shall establish and maintain a listing of approved Level I sub-tier suppliers. b) Suppliers who procure material or services used in Level I applications from sub-tier suppliers must assure their sub-tier suppliers of such materials are compliant with the material control and traceability requirements of the Purchaser’s purchase order. Suppliers are required to perform on-site audits of their sub-tier suppliers of Level I material unless one of the following applies: 1) The sub-tier supplier is an approved Level I Supplier of the Purchaser at the time of PO issue (available upon request from the Purchaser’s Buyer) 2) The starting material is sample tested (one sample per heat/lot) at Receipt Inspection for both chemistry and mechanical properties by a test laboratory other that the sub-tier supplier or mill and comparted to the applicable specification for acceptance. NOTE: A supplier who is qualified to perform quantitative chemical analysis and/or mechanical analysis has been audited as a test laboratory is considered a test laboratory.
