VERIFICATION4.1 Classification of inspections. The
34、 inspection requirements specified herein are classi-fied as follows:(a) First article inspection (see 4.2)(b) Conformance inspection (see 4.3)4.2 First article inspection.4.2.1 Sample. Unless otherwise specified in the contract, the first article sample shall consistof 8 adsorber cells consecutivel
35、y manufactured using the same methods, materials, equipment,and processes as will be used during regular production. The first article sample shall be sub-mitted for inspection and approval in accordance with the terms of the contract.4.2.2 Inspections to be performed. Unless otherwise specified by
36、the terms of the contract,the sample first article items shall be subjected to all of the examinations and test specified inthis specification and shall be inspected for compliance with all of the requirements of the ap-plicable packaging requirements. All nondestructive tests shall be performed bef
37、ore destruc-tive tests.4.2.3 Acceptance criteria. If any first article sample item fails to comply with any of the ap-plicable requirements, the first article sample shall be rejected. The Government reserves theright to terminate inspection upon any failure to comply with any of the requirements. T
38、he con-tractor shall obtain written approval from the proper authority of the contracting activity beforeproceeding with regular production. Once the contractor has proper approval to proceed intoregular production, the contractor shall then meet the quality conformance inspection require-ments (4.3
39、).4.3 Conformance inspection.4.3.1 Lotting. A lot shall consist of the adsorber cells produced by one manufacturer, at oneplant, from the same materials, under the same manufacturing and process conditions and with-out a break in production of more than 10 calendar days. Any one lot of cells shall c
40、ontain nomore than one lot of adsorbent media. A new lot of adsorber cells shall be started wheneverany adsorbent media filling or final assembly process equipment change is made. Each lot shallbe produced in its entirety before any adsorber cells of another lot are produced on that produc-tion line
41、.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-32016A(EA)74.3.2 Sampling. Inspection and test of random samples shall be conducted in accordancewith the classification of characteristics in 4.3.5 and, when specified, Table I.4.3.3 Inspectio
42、n procedure. Every item in the lot shall be inspected for critical characteris-tics. Sample adsorber cells shall be examined and tested in accordance with the classificationof characteristics in 4.3.5. If an adsorber cell is found that does not conform to any characteris-tic inspected 100%, such as
43、leakage and pressure drop requirements, the non-conforming ad-sorber cell shall be rejected and removed from the lot. For characteristics other than leakageand pressure drop, failure of any sample adsorber cell to conform to any major characteristic inthe classification of characteristics based on t
44、he sampling and acceptance criteria specifiedtherein shall be cause for rejection of the lot represented (see footnote, table I). If an adsorbercell is found that does not conform to any minor characteristic, the non-conforming adsorbercell shall be rejected and removed from the lot.4.3.4 Inspection
45、 characteristics. Critical characteristics are those whose nonconformanceto specified requirements is likely to result in hazardous or unsafe conditions for individualsusing, maintaining, or depending upon the product, characteristics whose nonconformance tospecified requirements is likely to preven
46、t performance of the tactical function of a major enditem. Major characteristics are those whose nonconformance to specified requirements is likelyto result in failure or to reduce materially the usability of the item for its intended purpose.Minor characteristics are those whose nonconformance to s
47、pecified requirements is not likelyto reduce materially the operation or usability of the item for its intended purpose.4.3.5 Classification of characteristics. Conformance examinations and tests shall be as spe-cified in the following classification of characteristics paragraphs. When specified her
48、ein, ac-cept on “0” and reject on “1” attributes sampling inspection shall be performed on thedesignated characteristics using the stated levels in table I for selection of sample sizes.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-32016A(EA)8TABLE I.
