NOTES FOR TABLE 1 (a) When specified in the applicable Inspection Operation Sheet (IOS) or directed by the Laboratory, the required specimen(s) representing each batch or lot shall be submitted to the Laboratory for testing. (b) Material which has not been ultrasonically inspected at the Seller s facility or does not conform to the receiving criteria shall be ultrasonically inspected as follows: (1) (Class A - special and Class AA) designated material as per the Engineering drawing shall be inspected 100% in accordance with GSS 16102. (2) (Class A or B) designated material as per the Engineering drawing shall be inspected as per a sampling plan established by Quality Engineering in accordance with MIL-STD-105. (c) When material print calls for Class A - Special, the parts must be inspected 100% pr GSS 16102. (d) DELETED (e) When the results of Material Test(s) (inspection) indicate the need for additional evaluation, a sample(s) shall be supplied to the Laboratory as per the Laboratory s requirements. (f) DELETED (g) Acceptance may be accomplished by the destructive testing of one piece per lot, when so specifically designated by the Inspection Operation Sheet (IOS) or directed by the Laboratory. (h) As specified in the Master Inspection List (MIL) or directed by Quality Engineering. (j) DELETED (k) Test specimen(s) of the type, size and quantity designed in the applicable process specification shall be forwarded to the Laboratory for evaluation. (l) Deleted (m) AQL noted is applicable only when a Certificate of Compliance (C of C) is included with the lot, otherwise 100% inspection is required. (n) Material test inspection shall not be required for raw steel material unless received in the final temper designation as directed by Quality Laboratory Operations and noted on the receiving report. (o) Material test inspection shall not be required for and raw material tested by Quality Laboratory Operations unless otherwise stipulated by the Laboratory and noted on the receiving report.

OTHER PARAMETERS Unless otherwise indicated by the Engineering Drawing or the Inspection Operation Sheet (IOS), the following types of characteristics shall be categorized into one of the above classifications, based upon seriousness of the defect and its potential impact upon satisfactory end-use of the part. Cleanliness - Micro Contaminants [measured in Parts per Million (PPM)]. Defects - Surface and Subsurface: Cracks, Porosity, Shrinkage, Voids Encapsulation - (Potting): Lack of Adhesion, Incomplete, Cracked, Excessive Finish - (Protective): Poor Adhesion, Porosity, Wrong Color Functional Performance: Per values of Specification or Test Procedure Joining Bonding Voids, Crushed Core, Lack of Bond, Brazing Flux Inclusions, Oxide Inclusions, Soldering, Cold or Excessive Filler Metal, Welding, Wicking, Lack of Penetration, Undercutting, Porosity, Excessive Indentation, Cracks Weight - As designated by drawing or specifications
