Sampling from Textile Lots for Laboratory Testing
topic
Laboratory sample selection from textile bales, rolls, and packages follows ISO 1130 and fibre-specific sampling standards, using systematic random selection of primary samples from defined positions within lots, followed by sample preparation procedures that reduce bulk samples to laboratory specimens while preserving the statistical representativeness of the primary selection.
Role
Ensures that laboratory test specimens are genuinely representative of the bulk textile lot from which they are drawn, preventing sampling bias from edge effects, surface exposure, and within-lot position effects that would invalidate the inference from laboratory specimen measurements to the quality of the total lot population.
