Standard Test Method f Consider the rolls of fabric to be the primary sampling units. Mass per linear yard: It may be impractical to condition the specimens in Option A or nonconditioned testing may f3776 agreed asm by the purchaser and supplier.
Mass per unit area: The last option is Option D which is intended for use with narrow fabrics as so designated by the trade. For die-cut specimens, the area of the die is normally given.
Your comments are invited either for satm of this standard or for additional standards and should be addressed to ASTM International Headquarters. Fabric mass is also sometimes expressed inversely as linear metres per kilograms yards per pound with the fabric width stated. Already Subscribed to this document. If insufficient fabric is available to meet these criteria, note that fact in the report.

Competent statistical assistance is recommended for the investigation of bias. The second option is Option B which is applicable to a full-width sample cut from a full piece, roll, bolt, or cut. Combining values from the two systems may result in non-conformance with the standard.
Option C—Small Swatch of D33776 9. The results are considered to be applicable to the sample only and not necessarily to the lot from which the sample was taken.
Two operators in each laboratory each tested two specimens of each material for mass per unit area.
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. Last previous edition approved in as D — The results are considered to be applicable to the sample only and not necessarily to the lot from which the sample was taken. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
There are four approved options in the measurement of fabric mass per unit area: Specimens of a fabric may be weighed together. Consider the rolls of fabric in the lot sample as the laboratory sample and as the test specimens. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing.
These fabrics are usually mm 12 in.
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 asm. No further reproductions authorized. 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.

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.
For other specimens, multiply the length by the width. Current edition approved July 1, NOTE 2—The tabulated values of the critical differences should be considered to be a general statement, particularly with respect to betweenlaboratory precision.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Prepare such specimens from small swatches as is possible.
