5.1 Upon mutual agreement between the purchaser and seller, fabrics intended for this end use should meet all the requirements listed in Table 1 of this specification.5.2 It is recognized that for purposes of fashion or aesthetics the ultimate consumer of articles made from these fabrics may find acceptable fabrics that do not conform to all of the requirements in Table 1. Therefore, one or more of the requirements listed in Table 1 may be modified by mutual agreement between the purchaser and seller.5.2.1 If any of the requirements in Table 1 are modified by mutual agreement between purchaser and seller, any reference to the specification shall state that: “This fabric meets ASTM Specification D4769, except for the following characteristic(s).”5.3 Where no prepurchase agreement has been reached between the purchaser and seller, and in case of controversy, the requirements listed in Table 1 are intended to be used as a guide only. As stated in 5.2, ultimate consumer demands dictate varying performance parameters for any particular style of fabric.5.4 The significance and use of particular properties and test methods are discussed in the appropriate sections of the specified test methods.1.1 This specification covers woven and warp knitted comforter fabrics, composed of any textile fiber, or mixture of fibers.1.2 These requirements apply to the length and width directions for those properties where fabric direction is pertinent.1.3 The following safety hazards caveat pertains only to the test methods described in this specification: 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.1.4 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.

5.1 This test method is considered satisfactory for acceptance testing of commercial shipments because it has been used extensively in the trade for that purpose.5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative test should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use the samples for such a comparative test that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data, a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.5.1.2 This test method is suitable for use with narrow fabrics when the count across the total width is measured in the narrow direction and extrapolated to the number of yarns per centimeter (inch).1.1 This test method covers the measurement of end (warp) and pick (filling) count and is applicable to all types of woven fabrics.NOTE 1: Historically, the term fabric count has been used to describe the end and pick count of woven fabrics. The terms end count and pick count are replacing the term fabric count, to provide clarity.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.2.1 Throughout this document, there will be some instances in which the units do not convert 1:1. This is to acknowledge that this is a global document and that different parts of the world use different units of measurement. Organizations using the metric system wil report the count per 1 cm. Organizations using the English system will report the count per 1 in.1.3 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.NOTE 2: For a current test method for the wale and course count of weft knitted fabrics, refer to Test Method D8007.1.4 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.
