1.0 SCOPE AND PURPOSE
This procedure defines requirements for the control of Nonconforming Material.
This applies to the identification, control, reporting, and disposition of conforming material.
2.0 RESPONSIBILTIES
See Flow chart Page #5.
3.0 DEFINITIONS
NONCONFORMING MATERIAL or DISCREPANCY – any material that does not
comply with dimensional, visual or hydrostatic specifications, is damaged or was not
processed in the manner defined in the Quality Assurance Plan; or, any material/service not
meeting requirements set forth in the purchase order.
MRB – Material Review Board consisting of Product Development, Engineering, and
Manufacturing, and the ensuing agreement of the Quality Assurance Manager.
Defect –Out-of-specification condition, resultant from faults in “visual appearance design,
process, procedures, that require reporting” using the Discrepant Material Form.
Root Cause Analysis – Determining the actual root cause of the defect will be determined by
the following departments:
Hydrostatic Implosions / Failures: Product Development
Mixing issues: Engineering Assistant
Workmanship issues: Control Configuration Officer

5.0 PROCEDURE
5.1 All suspect nonconforming material shall be identified by the DMR. Defects reported
using the Discrepant Material Report (DMR), form number F4-8.3-F001. All discrepant
material shall be identified and segregated (if possible) to prevent further processing
during the nonconforming material control process. Defective product shall be
indentified using Form F4-8.3-F001, or Red Reject Tag.
5.2 The discrepancy is documented clearly, concisely, and in sufficient detail using photos
as well to describe exactly what the discrepancy is. References to associated
documents and specification shall be noted when applicable.
5.3 When a DMR is initiated, the originator shall use the next DMR number from the DMR
Log book. The DMR number shall be noted in the space provided on the DMR form.
Electronic copies “are then distributed to individual(s) notated at the “Assigned to:”
Hard copies with the product traveler “are given to “Assigned to:” at the morning
production meeting. The DMR # will be transferred to the traveler to demonstrate full
traceability.
5.4 The discrepancy noted on the DMR by Quality Assurance is reviewed by one or more
individuals on MRB to disposition the defective part(s). If the part(s) require rework,
adequate instructions are to be applied in the Disposition field. Immediate corrective
action is defined by the MRB action. “Possible dispositions include” UAI = Use as is;
RTV = Return to Vendor; REWORK; REPAIR; SCRAP; Other (Specify).
5.5 Cycle time of the disposition of the DMR is a maximum of 10 working days. The cycle
time of closing the DMR is a maximum of 30 working days. Extreme cases where a
CAR is required, cycle time to close the DMR will take longer. The exception to this is
when Corrective Action is linked to the discrepancy.
5.6 If needed a root cause analysis will be performed and the findings will be attached to
the DMR. The department assigned to this exercise is described in section 3.0 of this
procedure.
5.7 Agreement is demonstrated by Engineering or Manufacturing signature and is required
for all DMR dispositions. If customer concurrence is necessary, the Project Manager
will inform the customer of the nonconformance and forward a copy of the DMR to the
customer representative. The customer will return a signed copy of the DMR to
Cuming Corp. for inclusion in the customer job file.
