4.1.1 Certificate of compliance. When certificates of compliance for test requirements are submitted, the Government reserves the right to inspect such items to determine the validity of the certification. Certificates of compliance shall be accompanied by actual test results dated not more than one year prior to the date of the start of the contract or date of purchase order. The contractor shall provide the name and address of the laundry where the rags have been washed, rinsed, and sanitize if this process is not performed by the contractor.

4.2 Sampling. Unless otherwise specified, sampling shall be in accordance with MIL-STD-105.

4.3 Lot formation. All bales of wiping rags of the same grade and color from the same manufacturer offered for delivery at one time shall be considered a lot for purposes of inspection.

4.4 Weight/volume verification. Select 10 bales from the lot and determine the minimum net weight per bale. The average minimum weight of the bales shall be 50 lb (22.7 kg). Any single weight determination of less than 49.75 lb (22.6 kg) shall be cause for rejection of the lot (see 3.8).

Select 5 of the 10 bales and determine the volume of each bale. Any bale measuring greater than 3.5 ft³ (0.1 m³) in volume shall be cause for rejection of the lot (see 3.8).

4.5 Sampling for visual and dimensional examination. For the purpose of visual and dimensional inspection, the lot shall be defined as the number of rags submitted for inspection (this shall be the number of bales multiplied by 200, the approximate number of rags per bale). Sampling shall be in accordance with inspection level S-4, AQL 2.5 percent defective per major defects and 4.0 percent defective for minor defects. The sample unit shall be one rag. No more than five rags shall be selected from any one sample bale. Rags shall be selected at random and examined for the defects as listed in Table I. During this examination, if any rag is suspected of not containing cotton by visual examination or by feel, all rags in the sample are to be tested in accordance with 4.7.3. If any rag fails the test in accordance with 4.7.3, it shall be classified as a major defect.
