Precision and Bias Combining values from the two systems may result in non-conformance with the standard. Option C—Small Swatch of Fabric 9. Consider rolls of fabric to be the primary sampling units. Option C on the other hand is applicable when a small swatch of fabric is sent to the laboratory to be used as the test specimen. Please first verify your email before subscribing to satm.

For other specimens, multiply the length by the width. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. NOTE 2—The tabulated values of the critical differences should be considered to be a general s3776, particularly with respect to betweenlaboratory precision.
