The material certification report must completely and accurately reflect that the material supplied meets the specified requirements. Materials requiring Traceability and Certification Data are identified within Paragraph 3, Section C of this contract/purchase order. 3.18.1 The following provides the minimum requirements for maintaining material traceability and supplements the requirements specified in DI-MISC-81020 and elsewhere in the contract/purchase order. The Contractor must develop written procedures that implement the material control requirements stated herein and elsewhere in this Contract/Purchase Order. 3.19 Material Traceability - The certification data report must be identified through a unique traceability number, heat-lot number, or heat-treat number, as applicable, which must also be marked on the material. This traceability marking on the material must provide direct traceability to the material's chemical composition and mechanical properties certification data. For material produced by batch, continuous cast, or continuous pour processes, samples must be taken no less than once in every eight hours of operation for the purpose of validating proper chemical composition and mechanical properties. Traceability must be maintained through all process operations including any subcontracted operations, to the finished component. 3.19.1 Material Marking for Traceability and Identification - The following are the minimum marking requirements. Additional/alternate marking requirements, if applicable, will be specified elsewhere in the contract/purchase order. In addition to the marking requirements on applicable drawings and/or specifications, marking for traceability is required. All traceability markings must be permanently applied in accordance with MIL-STD-792 (except as specified below). An alternate marking method is permissible provided it is an available option in the contractually invoked specification or drawing, except in instances where the material has been modified by this contract/purchase order and differs from that specified in the specification or drawing. 3.19.2 Traceability markings for items with precision machined or plated surfaces, or material with suitable marking surface areas less than 3/8 inches square (either 3/8" x 3/8" or an area equal to 0.1406 inches square) must be applied to a durable tag and the tag securely affixed to the material. 3.19.3 Marking must be legible and must be located so as to not affect the form, fit, and function of the material. ; ; 3.20 See CDRL DI-MISC-81020 (Chemical and Mechanical) - Material Certification - In addition to the certification data requirements specified in DI-MISC-81020, the following material certification requirements apply: 3.20.1 Quantitative chemical and mechanical analysis of material traceable to traceability markings is required. Material certification test reports must include the class, form, condition, grade, type, finish, and/or composition, as applicable, of the material supplied. 3.20.2 Re-identification and re-certification of material is required when the material is subjected to a process which alters it's properties. If the starting material or raw stock is processed in a manner that will not affect its chemical composition or mechanical properties, the original certifications for the chemical composition and mechanical properties, as required by the material specification, are acceptable. Re-certification of the chemical or mechanical properties is required if a process is used during fabrication that alters the original properties of the material (e.g. alloying, heat treating, or forming). In these instances, the properties of the material must be re-determined and documented to reflect the altered condition. The altered material must be uniquely re-identified with a new traceability number. The properties thus determined and documented, are required for final certification and must conform to the material specification or the contract/purchase order requirements. When only the mechanical properties are altered, the original certification forchemical composition must be overstamped and annotated with the unique traceability marking used with the altered material and at a minimum contain the information below. 3.20.3 Material certification data forwarded by the manufacturer must contain a signed certification that the report results represent the actual attributes of the material furnished and indicate full compliance with all applicable specification and contract requirements. Transcription of certification data is prohibited. 3.20.4 ELECTRONIC SIGNATURES. 3.20.5 Electronic signatures on Level I certification documents are consideredequivalent to handwritten signatures. 3.20.6 Suppliers that use electronic signatures to authenticate company certifications and reports must ensure that process is controlled and unique to the individual signing the document. The signer must take a distinct action to electronically sign the document 3.20.7 Suppliers must develop one method of authentication to be provided at the time of signature. The authentication method must be based on something known only to the signer (e.g., a password) or based on something only the signer possesses (e.g., a card or other device). 3.20.8 Electronic signature applications must not allow unauthorized users tochange electronically signed documents or records. All changes to electronically signed documents or records made by authorized users must be revision- or date-controlled, must identify the person making the change, and must clearly reflect that the document or record has been revised. 3.20.9 The prime contractor, as a minimum, must flow down the electronic signature requirements to their sub-tier suppliers and sub-contractors that provide electronically signed company certifications and reports to ensure that they have a procedure to control and identify unique processes for only allowing authorized individuals to sign documents. 3.20.10 Statements on material certification documents must be positive and unqualified. Disclaimers such as "to the best of our knowledge" or "we believe the information contained herein is true" are not acceptable. 3.20.11 If material is received without the required certification papers or with incorrect/missing data on the certification papers, the material will be rejected. 3.20.12 Revisions of OQE must be provided by the originating organization and must include a description of the data modified along with the proper signature requirements herein. 3.20.13 In cases of foreign certification, conversion of foreign language unitsof measure and properties measured into U.S. units of measure must be annotated on the furnished foreign certifications, if space permits, or placed on an addendum in the same format as the foreign certification data. Such conversion must be identified as to origin with name, title, and signature of the authorized representative of the company making the conversion. 3.20.14 The certification data requirements contained in this appendix must beinvoked on the prime contractor who must delegate these requirements to all sub-tier contractors supplying Level I material. 3.21 Material Handling - The written material control process must include the following: 3.21.1 All raw materials must have traceability markings (except as specified below). 3.21.2 Stored raw materials requiring traceability must be segregated to preclude intermingling with materials not requiring traceability. 3.21.3 When traceability markings will be removed by a manufacturing or fabrication process, the marking must be recorded prior to removal and be immediately restored upon completion of the process. If this cannot be done or is impractical, an appropriate material control procedure (such as a bag and tag, tagging, and/or tote box control) must be employed. The material control procedure must provide a method of positive control to preclude commingling of heats/lots or loss of traceability. The traceability marking must be reapplied upon completion of the final manufacturing process. 3.21.4 Brazing or weld filler metals for strength welds forming or integral with pressure containing components or assemblies requiring traceabil...
