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.
