Standards Subsctiption may be the perfect solution. The results are considered to be applicable asttm the sample only and not necessarily to the lot from which the sample was taken.
Precision and Bias Originally approved in The results are considered to be applicable to aztm sample only and not necessarily to the lot from which the sample was taken. D37776 the rolls of fabric in the lot sample as the laboratory sample and as the test specimens. Combining values from the two systems may result in non-conformance with the standard.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Competent statistical assistance is recommended for the investigation of bias. We have no amendments or d376 for this standard. Summary of Test Methods 4. Historical Version s – view previous versions of standard.
Option A may be used for acceptance testing of commercial shipments since d3776 has been used extensively in the trade. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
ASTM D – 96 Standard Test Methods for Mass Per Unit Area (Weight) of Fabric
Mass per unit area: These fabrics are usually mm 12 in. Option C on the other hand is ast when a small swatch of fabric is sent to the laboratory to be used as the test specimen.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. You may delete a document from your Alert Profile at any time. Option D—Narrow Fabrics Combining values from the two systems may result in non-conformance with the standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Last previous edition approved in as D — The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. Your comments are invited either for revision of this standard or e3776 additional standards and should be addressed to ASTM International Headquarters.
Option C—Small Swatch aastm Fabric 9.
The cut edges must be a straight line, free of indentations or bulges, unless both edges have been made to trace parallel?
In this procedure the complete laboratory sample is used as the specimen. Option B—Full Width Sample 8. The components of variance for fabric mass per unit area expressed as standard deviations were calculated to be as follows: Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Current edition approved July 1, Specimens of a fabric may be weighed together. Subscription pricing is determined by: 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 ast, the light of the known bias.

The last option is Option D which is intended for use with narrow fabrics as so designated by the trade. Unless otherwise specified, these results will include selvages and will be on the basis of conditioned fabric. Weights of unconditioned fabric will be affected by the past history of the product.

Need more than one copy? 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.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. For other specimens, multiply the length by the width.
Describe the material or product sampled and the method of sampling used. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Combining values from the two systems may result in non-conformance with the standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Prepare such specimens from small swatches as is possible. If insufficient fabric is available to meet these criteria, note that fact in the report. NOTE 2—The tabulated values of the critical differences should be considered to be a general statement, particularly with respect to betweenlaboratory precision.
