Standard Test Method for Thermal Resistance of Batting Systems Using a Hot Plate (Withdrawn 2023)

SIGNIFICANCE AND USE
4.1 The thermal resistance of a batting or batting/fabric system is of considerable importance in determining its suitability for use in fabricating cold weather protective clothing, sleeping bags, and bedding systems. The thermal interchange between man and his environment is, however, an extremely complicated subject which involves many factors in addition to the insulation values of fabrics and battings. Therefore, measured thermal insulation values can only indicate relative merit of a particular material.
SCOPE
1.1 This test method covers the measurement of the thermal resistance, under steady-state conditions, of battings and batting/fabric systems, and other materials within the limits specified in 1.2. It measures the heat transfer from a warm, dry, constant-temperature, horizontal flat-plate up through a layer of the test material to a cool atmosphere and calculates the resistance of the material. The measurements are made under still air conditions (Option #1) or with a horizontal air flow over the specimen (Option #2).  
1.2 For practical purposes, this test method is limited to determinations on specimens of battings and layered batting/fabric assemblies having an intrinsic thermal resistance from 0.1 to 1.5 K·m2/W and thicknesses not in excess of 50 mm.  
1.3 This test method also provides a method for determining the bulk density of the material, the insulation per unit thickness, and the insulation per unit weight.  
1.4 The values stated in SI units are to be regarded as standard.  
1.5 This standard does not purport to address the safety concerns associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This test method covers the measurement of the thermal resistance, under steady-state conditions, of battings and batting/fabric systems, and other materials within the limits specified in 1.2. It measures the heat transfer from a warm, dry, constant-temperature, horizontal flat-plate up through a layer of the test material to a cool atmosphere and calculates the resistance of the material. The measurements are made under still air conditions (Option #1) or with a horizontal air flow over the specimen (Option #2).
Formerly under the jurisdiction of Committee D13 on Textiles, this test method was withdrawn in January 2023 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Thermal Resistance of Batting Systems Using a Hot Plate
This standard is issued under the fixed designation D1518; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This standard replaces D1518-85, Thermal Transmittance of Textile Materials. This standard
provides a method for measuring the thermal resistance (insulation) provided by battings and
batting/fabric systems under still air conditions or an air flow condition. Other hot plate standards
F1868 and ISO 11092 provide a method for measuring the thermal resistance and evaporative
resistance of fabrics and fabric systems.The method for measuring fabric insulation in these standards
is comparable to Option 2:Air Velocity Condition in D1518. These standards can be used to compare
the thermal properties of textile materials. Manikin standards F1291 and F2370 can be used to
measure and compare the thermal resistance and evaporative resistance of clothing systems,
respectively. Manikin standard F1720 can be used to measure the insulation provided by sleeping bag
systems.
