performed in accordance with ANSI/ASQC Z1.4.
4.3.1 Examination. Each vest and hose assembly shall be examined for compliance with the
requirements specified in section 3 and subsequent government drawings. In accordance with
4.1, components and materials shall be inspected in accordance with all the requirements of
referenced documents unless otherwise excluded, amended, modified, or qualified in this
specification or applicable purchase document.
In addition, the first production lot or each of the components listed below shall be examined for
conformance to all dimensions specified on the referenced drawings. Any dimension exceeding
the applicable tolerance specified on the applicable drawing shall be classified as a defect. The
lot sizes shall be expressed in units of components. The sample unit shall be one component.
For each component lot, the inspection level shall be S-1 and the acceptable quality level (AQL),
expressed in terms of defects per hundred units, shall be 1.5. Failure of any lot shall be cause for
correction of the mold or process and for examination of the next produced lot from that mold or
process. Any subsequent lot in which a change in materials, mold, or process has occurred shall
be examined as above. If there are no changes, subsequent lots shall be accepted on the basis of

4.4 In-process inspection. Inspection of subassemblies shall be made to ascertain that
construction details which cannot be examined in the finished products are in accordance with
specified requirements. The Government reserves the right to exclude from consideration for
acceptance, any material or service for which in-process inspection has indicated
nonconformance. Whenever nonconformance is noted, corrections shall be made to the parts
affected and lot in process. Components that cannot be corrected shall be removed from
production.
4.4.1 End item visual examination. The end items shall be examined for the defects listed in
table I. The lot size shall be expressed in units of vests. The sample unit shall be one completely
fabricated vest. The inspection level shall be II and the AQL, expressed in terms of defects per
hundred units, shall be 1.5 for major defects and 6.5 for total (major and minor combined)
defects.
