4.2.1 Lots. A lot shall consists of one day's production or processing of bearings,

regardless of bearing dimensions, subject to the same packaging method and cleanliness level.

4.2.1.1 Sampling. As a minimum, the contractor shall randomly select a sample quantity

from each lot of completed packages in accordance with general inspection level I of ASQ Z1.4.

The acceptable quality level (AQL) shall be as identified in the contract or purchasing order

(see 6.2). In addition, the following sampling shall be accomplished:

4.2.1.1.1 Sampling for heat seal test (see 4.4.1). Samples from each heat sealer shall be

tested daily with each type of material used. If the heat sealer is dedicated to a specific material

and the temperature setting is not changed, the sealer may be tested monthly. The monthly

testing shall not be started until thirty days of continuous testing results with no failures. A log

shall be maintained for recording the results of this test by heat sealer. Sealers tested shall be

selected from intimate pack, primary, and secondary pack areas. Any failure shall require return

to daily testing until subsequent 30-day period has been met without failure.

4.2.1.1.2 Sampling for fingerprint corrosion and cleanliness test. A daily sample shall be

tested for fingerprint corrosion and cleanliness in accordance with 4.4.2 (not applicable to

ceramic materials). Daily samples shall consist of one day's production or processing of

bearings, regardless of bearing dimensions and subject to the same packaging method and

cleanliness level and shall be one of the following:
