1.1 This test method, known as the guarded hot box method, covers the measurement of the steady-state thermal transfer properties of panels. In distinction to Test Method C177, which is primarily applicable to homogeneous samples, the guarded hot box method provides for the evaluation of thermal performance of building assemblies. This test method is suitable for building construction assemblies, building panels, and other applications of nono-homogeneous specimens at similar temperature ranges. It may also be used for homogeneous specimens. 1.2 This test method may be applied to any building construction for which it is possible to build a reasonably representative specimen of size appropriate for the apparatus. Note 1-A calibrated hot box, Test Method C976, may also be used for the described measurements and may prove more satisfactory for testing assemblies under dynamic conditions (nonsteady-state) and to evaluate the effects of water migration and air infiltration. The choice between the calibrated or the guarded hot box should be made only after careful consideration of the contemplated use. 1.3 In applying this test method, the general principles outlined must be followed; however, the details of the apparatus and procedures may be varied as needed. 1.3.1 The intent of this test method is to give the essential principles and the general arrangement of the apparatus. Any test using this apparatus must follow those principles. The details of the apparatus and the suggested procedures that follow are given not as mandatory requirements but as examples of this test method and precautions that have been found useful to satisfy the essential principles. 1.3.2 Persons applying this test method shall be trained in the methods of temperature measurement, shall possess a knowledge of the theory of heat flow, and shall understand the general requirements of testing practice. 1.3.3 This standard does not purport to address all of the safety problems, if any, associated with its use. 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. Note 2-While various units may be found for thermal properties, the International System of units is used exclusively in this test method. For conversion factors to inch-pound and kilogram-calorie systems, see Table 1.

5.1 Sonic anemometer/thermometers are used to measure turbulent components of the atmosphere except in confined areas and very close to the ground. These practices apply to the use of these instruments for field measurement of the wind, sonic temperature, and atmospheric turbulence components. The quasi-instantaneous velocity component measurements are averaged over user-selected sampling times to define mean along-axis wind components, mean wind speed and direction, and the variances or covariances, or both, of individual components or component combinations. Covariances are used for eddy correlation studies and for computation of boundary layer heat and momentum fluxes. The sonic anemometer/thermometer provides the data required to characterize the state of the turbulent atmospheric boundary layer.5.2 The sonic anemometer/thermometer array shall have a sufficiently high structural rigidity and a sufficiently low coefficient of thermal expansion to maintain an internal alignment to within ±0.1°. System electronics must remain stable over its operating temperature range; the time counter oscillator instability must not exceed 0.01 % of frequency. Consult with the sensor manufacturer for an internal alignment verification procedure.5.3 The calculations and transformations provided in these practices apply to orthogonal arrays. References are also provided for common types of non-orthogonal arrays.1.1 These practices cover procedures for measuring one-, two-, or three-dimensional vector wind components and sonic temperature by means of commercially available sonic anemometer/thermometers that employ the inverse time measurement technique. These practices apply to the measurement of wind velocity components over horizontal terrain using instruments mounted on stationary towers. These practices also apply to speed of sound measurements that are converted to sonic temperatures but do not apply to the measurement of temperature using ancillary temperature devices.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.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.

3.1 The general approach to this practice is to serve as an “overlay” of requirements to the ASTM F3411-22a Standard Specification for Remote ID and Tracking by identifying mandatory portions, substituting values as needed, overriding items that may be optional, and providing additional requirements that are beyond the scope of Specification F3411, yet are necessary to provide proper guidance to meet the requirements set forth in Part 89.3.2 Furthermore, this practice provides additional details on minimal testing requirements for those submitting a DOC based on this MOC.1.1 This practice provides a Means of Compliance (MOC) that gives sufficient clarity to the Unmanned Aircraft System (UAS) or Broadcast Module manufacturers to produce a compliant Remote ID (RID) System (RIDS) such that submitting a Declaration of Compliance2 (DOC) to this MOC will satisfy the requirements of the Federal Aviation Administration (FAA) 14 CFR Part 89 (Part 89) rule.3 This practice also explains what to expect from aircraft operating in compliance to this MOC.1.2 The FAA provided three options to comply with the Remote ID regulations: Standard Remote ID UAS, Remote ID Broadcast Modules, and FAA-recognized identification areas (FRIAs). The scope of this MOC is to cover both Standard RID and RID Broadcast Modules.1.3 The FRIA portion of the rule is out of scope since it provides a means to avoid the technical RID requirements by operating within administrative boundaries.1.4 Both SI and non-SI units are used in this document. Since this is an aviation standard and it addresses FAA rules, some units are used in preference of being consistent with industry and regulatory norms.1.5 Table of Contents:Title Section 1Referenced Documents 2 3Subset of Options in the F3411 Specification Considered 4Requirements and Exceptions from the F3411 Specification 5Alternative Applications of Specification F3411 to Meet Part 89    Requirements 6MOC Requirements Not Covered by the Practice 7Test Methods 8Precision and Bias 9Satisfaction of Rule Requirements 10Keywords 11ANNEX A1—Simulation Option for Accuracy Testing Annex A1APPENDIX X1—External Device for GCS Location Source Rationale Appendix X1APPENDIX X2—Power Level Rationale Appendix X21.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 The crystallinity of UHMWPE will influence its mechanical properties, such as creep and stiffness. The reported crystallinity will depend on the integration range used to determine the heat of fusion, and the theoretical heat of fusion of 100 % crystalline polyethylene used to calculate the percent crystallinity in an unknown specimen. Differential scanning calorimetry is an effective means of accurately measuring both heat of fusion and melting temperature.5.2 This test method is useful for both process control and research.1.1 This test method discusses the measurement of the heat of fusion and the melting point of ultra-high-molecular weight polyethylene (UHMWPE), and the subsequent calculation of the percentage of crystallinity.1.2 This test method can be used for UHMWPE in powder form, consolidated form, finished product, or a used product. It can also be used for irradiated or chemically-crosslinked UHMWPE.1.3 This test method does not suggest a desired range of crystallinity or melting points for specific applications.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.

3.1 Measurement of dry film thickness of organic coatings by physically cutting through the film and optically observing and measuring the thickness offers the advantage of direct measurement as compared with nondestructive means.3.2 Constituent coating layers of an overall thickness of a coating system can usually be measured individually by this test method, provide adhesion between each layer is sufficient. (However, this can be difficult in cases where the primer, topcoat, or multiple coating layers have the same, or very similar, appearance.)FIG. 1 Typical Crater Formed by Boring DeviceNOTE 1: The drawing is not to scale. It is for illustration purposes only.NOTE 2: θ  = 5.710593°  Tan θ = A/B = 0.1   A = 0.1B1.1 This test method covers the measurement of dry film thickness (DFT) of coating films by microscopic observation of a precision-cut, shallow-angle crater bored into the coating film. This crater reveals cross sectional layers appearing as rings, whose width is proportional to the depth of the coating layer(s) and allows for direct calculation of dry film thickness.1.1.1 The Apparatus, Procedure, and Precision and Bias discussions include Method A and Method B. Method A involves the use of an optical measurement apparatus which is no longer commercially available, but remains a valid method of dry film measurement. Method B is a software driven measurement procedure that supersedes Method A.1.2 The substrate may be any rigid, metallic material, such as cold-rolled steel, hot-dipped galvanized steel, aluminum, etc. The substrate must be planar with the exception of substrates exhibiting “coil set,” which may be held level by the use of the clamping tool on the drilling device.NOTE 1: Variations in the surface profile of the substrate may result in misrepresentative organic coating thickness readings. This condition may exist over substrates such as hot-dipped, coated steel sheet. This is true of all “precision cut” methods that are used to determine dry film thickness of organic coatings. This is why several measurements across the strip may be useful if substrate surface profile is suspect.1.3 The range of thickness measurement is 0 to 3.5 mils (0 to 89 μm).NOTE 2: For DFT measurements of films greater than 3.5 mils (89μm), but less than 63 mils (1600 μm), a 45° borer may be used in accordance with this test method, with the exception of 6.8, where the micrometer reading would provide a direct read-out, and division by ten would be unnecessary per 4.3.1 Method A.1.4 Measurements may be made on coil-coated sheet, certain formed products, or on test panels.1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.6 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.1.7 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.
