A lot shall consist of actyl triethyl citrate produced at one plant with no change in formulation or process, If manufacture is by batch process, each batch shall constitute a lot. A batch shall be defined as in 6.3. the are sha s ha The 4.4 Acceptance samplinq, The number of
16、 containers to be chosen at random for acceptance sampling shall be equal to the square root of the total number of containers in the lot. If the number thus obtained is not a whole number, the number of containers to be sampled shall be increased to the next high whole number. In no case, however,
17、shall number of containers to be sampled be less than seven (unless there less than seven containers in the lot, in which case each container 1 be sampled), 4,4,1 Primary sample. From each selected container, a sample 1 be taken from three or more places throughout the container. total weight of the
18、 samples taken from each container shall weigh at least 50 granis (g)u placed in a clean, dry container, and labeled to identify the material name, original container designation, contract number, and lot number, Eacn sample thus taken shall be mixed thoroughly, 4,4.2 Composite sample. Each primary
19、sample shall be subdivided to prepare a composite sample (not in excess of 500 9). material not used shall be returned to the primary sample container, After mixing the composite sample thoroughly, place the composite sample in a clean, dry container; seal and identify the composite sample with the
