In this procedure a complete laboratory sample is used as a specimen. The components of variance for fabric mass per unit area expressed as standard deviations were calculated to be as follows: Combining values from the two systems may result in non-conformance with the standard.
Combining values from the two systems may result in non-conformance with the standard. Consider the roll of fabric to be the primary sampling x3776. Mass per linear yard: 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. Such results may not correspond with the results obtained after testing adequately conditioned specimens in the standard atmosphere for testing textiles.

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.
These fabrics are usually mm 12 in. These test methods cover the measurement of fabric mass per unit d7376 weight and is applicable to most fabrics. Standards Subsctiption may be the perfect solution. Competent statistical assistance is recommended for the investigation of bias.
Last previous edition approved in as D — The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. You can download and open this file asgm your own computer but DRM prevents opening this file on another computer, including a networked server. Mass per unit area: It may be impractical to condition the specimens in Option A or nonconditioned testing asgm be agreed upon by the purchaser and supplier.
The results are considered to be applicable to the sample only and not necessarily to the lot from which the sample was taken. When 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.

Prepare such specimens from small swatches as is possible. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Fabric Weight ASTM Test Method D3776
The cut edges must be a straight line, free of indentations or bulges, unless both edges have been made to trace parallel? Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Subscription pricing is determined by: The second option is Option B which is applicable to a full-width sample cut from a full d7376, roll, bolt, or cut. If insufficient fabric is available to meet these criteria, note that fact in the report.

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. A number in parentheses indicates the year of last reapproval. For other specimens, multiply the length by the width. Weights of unconditioned fabric will be f3776 by the past history of the product. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
Specimens of a fabric may be weighed together.

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.
Standard Test Method f Precision and Bias The last option is Option D which is intended for use with narrow fabrics as so designated by the trade. The values stated in each system may not be exact equivalents; therefore, each system shall be ast independently of the other. Measurements by this method do not include selvages and should be reported as such, unless a selvage allowance is specified.
In this procedure the complete laboratory sample is used as the specimen. There are four approved options in the measurement of fabric mass per unit area: This standard is not included in any packages. If the document is revised or amended, you will be notified by email.
