4.4.1 Component testing. In addition to any testing required by 4.4, components listed in table V
shall be tested for the characteristics noted. The lot and sample sizes shall be as follows:
Lot Size
Sample Size
800 or less
2
801 to 22,000 inclusive
3
22,001 and over
5
The lot shall be unacceptable it one or more sample units fail to meet any test requirement
specified. The lot size units and the sample units shall be as follows:
Component
Lot Size Unit
Sample Unit
Slide fastener tape
Yard
1 Yard
Insulating material (liner)
Yard
1 Yard full width
4.4.2 In-process inspection. Inspection shall be made at any point or during any phase of the
manufacturing process to determine whether construction details which cannot be examined in
the finished product are in accordance with specified requirements. This inspection shall include
verification that the working patterns conform to the Government patterns in all respects.
Whenever nonconformance is noted, corrections shall be made to the items affected and the lot
in process. Items which cannot be corrected shall be removed from production.

4.4.2.1 Adhesion testing of fusibles. Prior to fusing each 2000 parts, a sample of equivalent area
to a part shall be fused for visual and adhesion testing. After visual examination for bubbling,
delamination and bleed through, the sample shall be cut to a 1-inch width and peeled in the warp
direction using a spring scale or suitable device capable of measuring the peel strength in ounces.
Any sample failing the minimum peel strength requirements specified 3.2.3 or showing any
bubbling, delamination or bleed through shall be cause for rejection of the previous 2000-fuse
parts. No fusing shall be performed after the rejection of a 2000-part lot until the machine has
been properly adjusted to produce a passing sample. The rejected lot shall then be replaced with
a shade-matched lot which has been fused correctly. Rejection of the previously fused parts shall
not apply to the first sample tested after machine warm-up.
