Option D—Narrow Fabrics Your Alert Profile lists the documents that will be monitored. For other specimens, multiply the length by the width. Competent statistical assistance is recommended for the investigation of bias. Fabric mass is also sometimes expressed inversely as linear metres per kilograms yards per pound with the fabric width stated.
The last option is Option D which is intended for use with narrow fabrics as so designated by the trade.
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. Take a minimum of three such laboratory samples from different places, distributed as evenly as practicable along the length of the roll or piece. It may be impractical to condition the specimens in Option A or nonconditioned d776 may be agreed upon by the purchaser and supplier.
ASTM D/DMae1 – Standard Test Methods for Mass Per Unit Area (Weight) of Fabric
Weights of unconditioned fabric will be affected by the past history of the product. The asttm stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.
Combining values from the two systems may result in non-conformance with the standard. Historical Version s – view previous versions of standard.
In this procedure the complete laboratory sample is used as the specimen. Consider rolls of fabric to be the primary sampling units. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. NOTE 2—The tabulated values of the critical differences should be considered to be a general statement, particularly with respect to betweenlaboratory precision.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. These test methods cover the measurement of asfm mass per unit area weight and is applicable to most fabrics. Consider the rolls of fabric to be the primary sampling units.
As a minimum, the 3d776 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. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

The accuracy of the scale should be certi? This standard is not included in any packages. The cut edges must be a straight line, free of indentations or bulges, unless both edges have been made to trace parallel?
Consider the roll of fabric to be the primary sampling units. Consider the rolls of fabric in the lot sample as the laboratory sample and as the test 3d776.
Standards Subsctiption may be the perfect solution. Seersucker Gingham Corduroy Denim 0. Such results may not correspond with the results obtained after testing adequately conditioned specimens in the standard atmosphere for testing textiles. Last previous edition approved in as D — Precision and Bias Add to Alert PDF.
In this procedure a complete laboratory sample is used as a specimen. Need more than one copy? Option A may be used for acceptance testing of commercial shipments since it has been used extensively in the trade. 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.

The results are considered to be applicable to the sample only and not necessarily to the lot from which the sample was taken. Option C—Small Swatch of Fabric 9. ASTM D seam str There are four approved options in the measurement of fabric mass per unit area: As the voice of the U. Measurements by this method do not include selvages and should be reported as such, unless a selvage allowance is specified.
Two operators in each laboratory each tested two specimens of each material for mass per unit area.
