Incomplete sampling
Websampling unit (e.g., purging with humidified HCF zero air overnight or longer) and repeat the zero-air challenge. You must not use a sampling device that has not met the standards in this section. Note: If extended purging durations are not adequate to eliminate contaminants, then disassemble and clean according to Section 8.4 of this method. WebHere are a few simple steps to reduce sampling error: Increase sample size: A larger sample size results in a more accurate result because the study gets closer to the actual population size. Divide the population into groups: Test groups according to their size in the population instead of a random sample.
