Except as otherwise specified in the contract! the contractor may use his own or any other facilities suitable for the performan

32、ce of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure that supplies and services conform to prescribed requirem

33、ents. 4.1.1 The supplier shall submit to the contracting officer a certificate of compliance indicating that the adhesive complies with the shelf storage life requirement as specified in 3.11.

Sampling of the adhesive shall be performed as directed by the procuring agency either (a) in a thoroughly-mixed batch of adhesive before packaging, or (b) on a lot of packaged adhesives (filled containers). Sampling for preparation for delivery shall be

36、 made on the packaged, or packaged and packed lot. 4.2.3 Examination of filled containers. When the examination is to be performed on filled containers, a random sample of such containers shall be selected for examination from each lot in accordance with MIL-STD-105.

The condition in the container shall be determined as follows: Each container in the sample shall be opened and sufficient adhesive shall be poured into a clean, dry vessel to permit the remainder of the adhesive

39、 to be stirred without spilling. The adhesive shall be stirred with a clean paddle reaching to the bottom of the container, presence of segregation, caking, lumps, skins or solid particles shall be observed! and differences in consistency between sample units shall be determined by feeling the resis

40、tance to movement of the paddle and by observing the material as it drains off the paddle. shall then be returned to the container.
