SIGNIFICANCE AND USE
5.1 Option A procedures of Test Method D3774 for width are considered satisfactory for acceptance testing of commercial shipments because they are used extensively in the trade.
5.1.1 In case of a dispute arising from differences in reported test values when using Test Method D3774 for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. 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. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before testing is begun. 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.
SCOPE
1.1 This test method covers the measurement of the width of woven or knitted fabrics, usable width, or both. The method is applicable to full rolls, bolts of fabric, and short specimens removed from a roll or bolt. Unless otherwise specified, measurements shall include the selvages when present.
1.2 The method offers two options:
1.2.1 Option A—Full Roll or Bolt.
1.2.2 Option B—Short Specimen Removed from Full Roll or Bolt.
1.3 The values stated in either SI units or U.S. customary units are to be regarded as standard. The U.S. customary units may be approximate.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM D3774-18 is the internationally recognized standard test method for measuring the width of textile fabrics. Developed by ASTM International, this method supports accurate and consistent measurement practices across woven and knitted fabrics, including those with pile, napped, or raised surfaces. The standard is vital for quality control, product specification, and trade of textile materials, providing reliable procedures for acceptance testing of commercial shipments.
ASTM D3774-18 is applicable to full fabric rolls, bolts, and short specimens. It allows the measurement of both total and usable fabric width, including selvages unless specified otherwise. The test can be performed with fabrics laid tension-free or under specific finishing conditions, making it adaptable to various production and inspection environments.
Key Topics
- Measurement Procedures
- Option A: For full rolls or bolts, offering both tension-free and tension-applied measurement methods
- Option B: For short specimens cut from rolls or bolts, suitable when only small fabric samples are available
- Measurements include selvages unless directed otherwise
- Sampling and Conditioning
- Roll or bolt selection is randomized according to material specification or mutual agreement
- Fabric specimens must be conditioned following recognized textile testing practice (ASTM D1776) where possible
- Reporting Requirements
- Clear documentation of the specimen description, measurement option, tension use, measured width (full or usable), and measurement conditions
- Inclusion of minimum, maximum, and average width values, along with testing conditions
- Precision and Bias
- Option A is considered free of bias and is widely accepted as a referee method
- Statistical guidance is provided for resolving interlaboratory differences, using comparative tests and Student’s t-test
- Applicability
- Applies to both commercial acceptance testing and laboratory evaluation
- Suitable for a wide range of woven, knitted, circular-knitted, raised-surface, and shuttleless loom fabrics
Applications
ASTM D3774-18 is widely used in the textile industry by manufacturers, suppliers, and buyers to:
- Quality Assurance and Control:
Ensure that fabric width meets design specifications and contractual requirements through standardized testing practices - Acceptance Testing:
Provide a reliable and mutually recognized means for evaluating commercial fabric shipments prior to acceptance and payment - Dispute Resolution:
Establish objective measurement procedures for resolving disputes between suppliers and purchasers over reported fabric widths - Laboratory Testing:
Facilitate evaluation of fabric samples during product development and production, especially when only swatches or short samples are available
This standard enhances trust across the textile supply chain by promoting consistency, transparency, and reproducibility in fabric width measurement.

4.2 Option A offers two procedures for the measurement of fabric width, or pile width or napped surface width, or both, width
in full rolls or bolts. Raised (pile or napped) surface width or usable width may be measured in addition to, or in place of, the full
width. The first procedure is essentially a tension-free method,method; the second procedure provides for measurements made
during finishing or inspection operations that may impart tension to the fabric.
4.3 Option B covers the measurement of fabric width, pile surface width or napped surface width, or both, width when only
a short length of fabric is available for testing. This procedure is applicable when a small swatch of fabric is sent to the laboratory
to be used as the test specimen.available. Raised (pile or napped) surface width or usable width may be measured in addition to,
or in place of, the full width.
5. Significance and Use
5.1 Option A procedures of Test Method D3774 for width are considered satisfactory for acceptance testing of commercial
shipments because they are used extensively in the trade.
5.1.1 In case of a dispute arising from differences in reported test values when using Test Method D3774 for acceptance testing
of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias
between their laboratories. Competent statistical assistance is recommended for the investigation of bias. 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. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average
results from the two laboratories should be compared using Student’s t-test for unpaired data and an acceptable probability level
chosen by the two parties before testing is begun. 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.
6. Apparatus
6.1 Measuring device, metremeter (yard) stick or steel tape having 1-mm ( ⁄16-in.) graduations and a length that is greater than
the width of fabric to be measured.
7. Sampling
7.1 As a lot sample for acceptance testing, take at random the number of rolls of fabric as directed in an applicable material
specification or other agreement between the purchaser and the supplier.
7.2 For Option A, consider rolls of fabric to be the primary sampling units. Consider the rolls of fabric in the lot sample as the
laboratory sample and the points at which measurements are made within the rolls as test specimens. Circular knits may be
measured in tubular or slit form.
7.3 For Option B, cut a full width swatch at least 2 m (2 yd) long from each lot sampling unit as a laboratory sampling unit,
taking care that the weaveconstruction is not distorted within the swatches. Consider the points at which the measurements are
made within the swatchswatches as test specimens. This option is not suitable for acceptance testing because the results are
applicable to that swatch only.those swatches only. Circular knits may be measured in tubular or slit form.
8. Conditioning
8.1 Condition the specimens as directed in Practice D1776.
8.2 When 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. Such results may not correspond with
the results obtained after testing conditioned specimens in the standard atmosphere for testing textiles.
9. Procedure
9.1 Make all measurements, when possible, in the standard atmosphere for testing textiles, which is 21 6 12 °C (70 6 24 °F)
and 65 6 2 %5 % relative humidity.
9.2 Option A—Full Roll or Bolt:
