SAMPLING
3. General Requirement
3.1 The seller shall have the option of being represented at the time of sampling and when he so requests, shall be furnished
with a duplicate sample.
4. Powders and Flakes Packed in Cans or Cartons
4.1 Take one can or carton at random from not less than 1% of the seller’s shipping containers, provided each package contains
not less than 50 lb (22.7 kg). In the case of smaller containers, take a can or carton at random from each lot of containers totaling
not more than 5000 lb (2268 kg) or fraction thereof. The gross sample shall in all cases consist of not less than three cans or cartons
taken at random from separate containers. In the case of very large lots where the sample drawn as above will amount to more
than 20 lb (9.1 kg), reduce the percentage of packages sampled so that the amount drawn will not exceed 20 lb (9.1 kg). Tightly
wrap the individual cans or cartons at once in paraffined paper and seal by rubbing the edges with a heated iron. The inspector shall
accurately weigh each wrapped can or carton and record its weight and the date of weighing on the wrapper. Place the wrapped
cans or cartons in an airtight container, which should be nearly filled, and which shall then be sealed, marked, and sent to the
laboratory for test. Samples shall be kept cool until tested.
5. Powders and Flakes in Bulk
5.1 Take a grab sample of not less than 0.5 lb (227 g) at random from not less than 1 % of the seller’s shipping containers,
provided each package contains not less than 100 lb (45.4 kg). In the case of smaller containers, take a grab sample of not less
