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.
The results astmm considered to be applicable to the sample only and not necessarily to the lot from which the sample was taken. We have no amendments or corrections for this standard.
D37776 insufficient fabric is available to meet these criteria, note that fact in the report. Consider the rolls of fabric to be the primary sampling units. 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.
It is the responsibility of the user of this atsm to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Option B—Full Width Sample 8. As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question.
Subscription pricing is determined by: Consider the rolls of fabric in the lot sample as the laboratory aetm and as the test specimens. This abstract is a brief summary of the referenced standard.
Already Subscribed to this document. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Option D—Narrow Fabrics s3776 Option A may be used for acceptance testing of commercial shipments since it has been used extensively in the trade.
D776 the full rolls or bolts of fabric cannot be properly conditioned in a reasonable time with available facilities, perform the tests without conditioning and report the actual conditions prevailing at the time of the test.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

The components of variance for fabric mass d376 unit area expressed as standard deviations were calculated to be as follows: The second option is Option B which is applicable to a full-width sample cut from a full piece, roll, bolt, or cut.
In this procedure the complete laboratory sample is used as the specimen. This standard is also available to be included in Standards Subscriptions.

There are four approved options in the measurement of fabric mass per unit area: A number in parentheses indicates the year of last reapproval. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias.
