A composite sample may contain from two to four subsamples of the same area as
each other and of each single surface sample in the composite. The weighted
arithmetic mean is obtained by summing, for all samples, the product of the

For example, the weighted arithmetic mean of a single surface sample containing
60 µg/ ft2, a composite sample (three subsamples) containing 100
µg/ ft2, and a composite sample (4 subsamples) containing 110 µg/
ft2 is 100 µg/ ft2. This result is based upon the equation (60+(3*100)
