Standard Specification for Performance for Weather Information Reports, Data Interfaces, and Weather Information Providers (WIPs)

Standard Specification for Performance for Weather Information Reports, Data Interfaces, and Weather Information Providers (WIPs)

SCOPE
1.1 In this specification, the standard of performance for weather information reports, analyses, and services performed by a weather information provider (WIP) in support of extensible traffic management (xTM) systems, unmanned aircraft systems (UAS) and vertical takeoff and landing (VTOL) systems operating from the surface to 5000 ft (1524 m) above ground level (AGL) are addressed.  
1.2 This specification does not define how to report a meteorological aerodrome report (METAR). This specification supports evolving international and the sovereign civil aviation authority (CAA) and air navigation service provider (ANSP) regulations.  
1.3 Relationship to International WIP Standards—One objective of this specification is to harmonize the standard across CAAs internationally to enable subject matter compatibility across standards developed by other standards development organizations (SDOs). The existence of multiple standards for the same subject matter can occur when a region’s regulator requires that a necessary standard be developed by a particular SDO. In these cases, ASTM International may seek to establish a cooperative arrangement with the applicable SDO to ensure consistency between the related standards.  
1.4 This specification provides an initial version to provide guidance to commercial aviation operations including, but not limited to, UAS and VTOL users, for weather measurements and analyses. Research and development activities will continue to inform and lead to modifications to this specification.  
1.5 This specification will not cover the standard of performance for weather forecasts.  
1.6 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.7 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.  
1.8 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.

ASTM D6866-24(Test Method)
Standard Test Methods for Determining the Biobased Content of Solid, Liquid, and Gaseous Samples Using Radiocarbon Analysis

SIGNIFICANCE AND USE
4.1 This testing method provides accurate biobased/biogenic carbon content results to materials whose carbon source was directly in equilibrium with CO2 in the atmosphere at the time of cessation of respiration or metabolism, such as the harvesting of a crop or grass living its natural life in a field. Special considerations are needed to apply the testing method to materials originating from within artificial environments. Application of these testing methods to materials derived from CO2 uptake within artificial environments is beyond the present scope of this standard.  
4.2 Method B utilizes AMS along with Isotope Ratio Mass Spectrometry (IRMS) techniques to quantify the biobased content of a given product. Instrumental error can be within 0.1-0.5 % (1 relative standard deviation (RSD)), but controlled studies identify an inter-laboratory total uncertainty up to ±3 % (absolute). This error is exclusive of indeterminate sources of error in the origin of the biobased content (see Section 22 on precision and bias).  
4.3 Method C uses LSC techniques to quantify the biobased content of a product using sample carbon that has been converted to benzene. This test method determines the biobased content of a sample with a maximum total error of ±3 % (absolute), as does Method B.  
4.4 The test methods described here directly discriminate between product carbon resulting from contemporary carbon input and that derived from fossil-based input. A measurement of a product’s 14C/12C or 14C/13C content is determined relative to a carbon based modern reference material accepted by the radiocarbon dating community such as NIST Standard Reference Material (SRM) 4990C, (referred to as OXII or HOxII). It is compositionally related directly to the original oxalic acid radiocarbon standard SRM 4990B (referred to as OXI or HOxI), and is denoted in terms of fM, that is, the sample’s fraction of modern carbon. (See Terminology, Section 3.)  
4.5 Reference standards, available to all...
SCOPE
1.1 This standard is a test method that teaches how to experimentally measure biobased carbon content of solids, liquids, and gaseous samples using radiocarbon analysis. These test methods do not address environmental impact, product performance and functionality, determination of geographical origin, or assignment of required amounts of biobased carbon necessary for compliance with federal laws.  
1.2 These test methods are applicable to any product containing carbon-based components that can be combusted in the presence of oxygen to produce carbon dioxide (CO2) gas. The overall analytical method is also applicable to gaseous samples, including flue gases from electrical utility boilers and waste incinerators.  
1.3 These test methods make no attempt to teach the basic principles of the instrumentation used although minimum requirements for instrument selection are referenced in the References section. However, the preparation of samples for the above test methods is described. No details of instrument operation are included here. These are best obtained from the manufacturer of the specific instrument in use.  
1.4 Limitation—This standard is applicable to laboratories working without exposure to artificial carbon-14 (14C). Artificial 14C is routinely used in biomedical studies by both liquid scintillation counter (LSC) and accelerator mass spectrometry (AMS) laboratories and can exist within the laboratory at levels 1,000 times or more than 100 % biobased materials and 100,000 times more than 1% biobased materials. Once in the laboratory, artificial 14C can become undetectably ubiquitous on door knobs, pens, desk tops, and other surfaces but which may randomly contaminate an unknown sample producing inaccurately high biobased results. Despite vigorous attempts to clean up contaminating artificial 14C from a laboratory, isolation has proven to be the only successful method of avoidance. Completely separate chemical ...

Standard Test Method for Charpy Impact Test on Thin Specimens of Polyethylene Used in Pressurized Pipes

SIGNIFICANCE AND USE
5.1 Brown and Lu4,5 show the Charpy impact energy is related to the ultimate critical temperature of the rapid crack propagation [RCP] behavior as measured by the ISO 13477, S-4 test.6  
5.2 The test method may be used to determine the impact energy of polyethylene used in the manufacture of pipe . This test method involves the preparation of a small compression molded specimen of PE resin that is then notched in a specified manner. The specimen is then broken in a pendulum impact machine. The impact energy is recorded in joules. The value obtained is referred to as the Charpy impact energy.
SCOPE
1.1 This test method describes the specimen preparation and the method of measuring the impact energy of polyethylene used in pressurized pipes.  
1.2 The test specimens are taken from compression molded plaques of the resin from pellets or pipe.  
1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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.

Standard Test Method for Evaluating Aerial Response Robot Endurance

SIGNIFICANCE AND USE
5.1 This test method is part of an overall suite of related test methods that provide repeatable measures of robotic system mobility and remote pilot proficiency. The operational endurance of a robot significantly impacts the performance of the robot during a variety of tasks. Robot endurance is a complex function of robot design, control scheme design, and energy storage selection. This test method evaluates the endurance of a robot through continuous operation. The outdoor and indoor movement tests flight path chosen for endurance testing specifically challenges robotic system locomotion, flight system to maintain position, and remote situational awareness by the remote pilot. As such, it can be used to represent modest outdoor flight or indoor flight within confined areas. The indoor hovering and dwelling tests similarly challenge these capabilities, but for remaining stationary in air within an outdoor or confined indoor area. The endurance test standard provides a method in which the operational endurance of a large variety of robot sizes and locomotion system designs may be compared. The test provides both a measure of the endurance of the robot and a measure of the reliability of the robot when operating continuously for extended periods of time on complex flight paths or continuous use, or both.  
5.2 The indoor tests with containment walls represent repeatable complexity within commercial spaces and residential dwellings with hallways and doorways, or warehouses.  
5.3 The test apparatuses are low-cost and easy to fabricate so they can be widely replicated. The procedure is also simple to conduct. This eases comparisons across various testing locations and dates to determine best-in-class systems and remote pilots.  
5.4 Evaluation—This test method can be used in a controlled environment to measure baseline capabilities. The endurance test apparatus can also be embedded into operational training scenarios to measure degradation due to uncontrolled variab...
SCOPE
1.1 This test method is intended for remotely operated aerial response robots (that is, unmanned aerial systems [UAS], drones, unmanned aircrafts) operating in complex, unstructured, and often hazardous environments. It specifies the apparatuses, procedures, and performance metrics necessary to measure the mission endurance of an aerial robot while either station keeping or following an approximate flight path defined by obstacles or boundaries, or both, intended to induce repeated cyclical movement. This test method is one of several robot tests that can be used to evaluate overall system capabilities.  
1.2 The robotic system includes a remote pilot in control of most functionality, so an onboard camera and remote pilot display are typically required. This test method can be used to evaluate assistive or autonomous behaviors intended to improve the effectiveness or efficiency of remotely operated systems.  
1.3 Different user communities can set their own thresholds of acceptable performance within this test method for various mission requirements.  
1.4 Performing Location—This test method may be performed anywhere the specified apparatuses and environmental conditions can be implemented. Flying unmanned aircraft without a comprehensive understanding of the laws and regulations enforced by the relevant jurisdiction poses significant safety and legal risks. Failure to comply with these regulations may result in accidents, injuries, property damage, and legal consequences. Users of this standard are strongly advised to review and adhere to all applicable ASTM Committee F38 standards and to ensure full compliance with the authorities holding jurisdiction.  
1.5 Units—The International System of Units (SI Units) and U.S. Customary Units (Imperial Units) are used throughout this document. They are not mathematical conversions. Rather, they are approximate equivalents in each system of units to enable use of readily ava...

Standard Specification for Polyethylene (PE) Plastic Pipe (DR-PR) Based on Outside Diameter

ABSTRACT
This specification covers polyethylene (PE) pipe made in dimensions based on outside determined range of diameters and larger. The piping is intended for new construction and insertion renewal of old piping systems used for the transport of water, municipal sewage, domestic sewage, industrial process liquids, effluents, slurries, etc., in both pressure and nonpressure systems. Different dimensional properties of pipes like outside diameter, wall thickness, eccentricity, toe-in, and special sizes shall be determined. Physical properties such asdensity, melt index, flexural modulus, tensile strength, slow crack growth resistance, hydrostatic strength, color and UV stabilizer, HDB, and HDS shall determined as well. In order to determine the performance of pipes under pressure the following tests shall be done: short-term pressurization test and elevated temperature sustained pressure test. The pipe shall be homogeneous throughout and essentially uniform in color, opacity, density, and other properties. The inside and outside surfaces shall be semi matte or glossy in appearance (depending on the type of plastic) and free of chalking, sticky, or tacky material. The surfaces shall be free of excessive bloom, that is, slight bloom is acceptable. The pipe walls shall be free of cracks, holes, blisters, voids, foreign inclusion, or other defects that are visible to the naked eye and that may affect the wall integrity. Holes deliberately placed in perforated pipe are acceptable. Bloom or chalking may develop in pipe exposed to direct rays of the sun (ultraviolet radiant energy) for extended periods and, consequently, these requirements do not apply to pipe after extended exposure to direct rays of the sun.
SCOPE
1.1 This specification covers polyethylene (PE) pipe made in three standard outside diameter sizing systems, based on outside diameters of DIPS 3, IPS 4, Metric 90 mm and larger. For smaller sizes refer to Specification D3035. See 5.2.5 for guidelines on special sizes.  
1.2 The piping is intended for new construction and insertion renewal of old piping systems used for the transport of water, municipal sewage, domestic sewage, industrial process liquids, effluents, slurries, etc., in both pressure and nonpressure systems.
Note 1: The user should consult the manufacturer to ensure that any mechanical or chemical effects to the polyethylene pipe caused by the material being transported will not affect the service life beyond limits acceptable to the user. See PPI TR-19 Chemical Resistance of Thermoplastic Piping Materials for guidance on chemical effects, www.plasticpipe.org  
1.3 All pipes produced under this specification are pressure-rated. See Appendix X5 for information on pressure rating.
Note 2: References and material descriptions for PE2406, PE3408 and materials having a HDB of 1450 psi have been removed from Specification F714 due to changes in Specification D3350 and PPI TR-3. For removed designations, refer to previous editions of Specification F714, Specification D3350, PPI TR-3 and PPI TR-4. The removal of these materials does not affect pipelines that are in service. See Note 4 and Note 9.  
1.4 This specification includes criteria for choice of raw material, together with performance requirements and test methods for determining conformance with the requirements.  
1.5 Quality-control measures are to be taken by manufacturers. See Appendix X4 for general information on quality control.  
1.6 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.7 The following safety hazards caveat pertains only to the test methods portion, Section 6, of 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 t...

Standard Test Methods for Rosin Acids Content of Pine Chemicals, Including Rosin, Tall Oil, and Related Products

SIGNIFICANCE AND USE
4.1 This is a revision of the method for measuring rosin acids content combines the three major ways of determining the rosin acids content of pine chemicals products into a single method.  
4.1.1 For materials containing less than 15 % rosin, the modified Glidden procedure has gained acceptance. For materials containing more than 15 % rosin the modified Wolfe Method is preferred. The modified Wolfe and modified Glidden procedures differ only in their details. They have been combined here into a single procedure. This procedure can be run using either a potentiometer or an internal indicator to determine the end point of the titration. Use of a potentiometer is preferred and is the referee method. Use of an internal indicator is the principal alternative method. They will be referred to as the Potentiometric Method and the Internal Indicator Method.
SCOPE
1.1 These test methods cover the determination of rosin acids in tall oil, tall oil fatty acid, tall oil rosin, and other pine chemicals products.  
1.2 These test methods may not be applicable to adducts or derivatives of rosin, fatty acid, or other pine chemicals products.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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.

Standard Test Method for Comparing the Brightness of Fluorescent Penetrants

SIGNIFICANCE AND USE
5.1 The principle use of this procedure is for the comparison of the brightness between batches of fluorescent penetrants compared to a specified standard, as a batch quality control test.  
5.2 The procedure is also utilized in monitoring the brightness of an in-use penetrant against the brightness of the unused sample of the same material.  
5.3 The significance of the results are not absolute values but rather relative comparisons at a point in time, by a particular laboratory or operator on the specified fluorometer.
SCOPE
1.1 This test method describes the techniques for comparing the brightness of the penetrants used in the fluorescent dye penetrant process. This comparison is performed under controlled conditions that eliminate most of the variables present in actual penetrant examination. Thus, the brightness factor is isolated and is measured independently of the other factors which affect the performance of a penetrant system.  
1.2 The brightness of a penetrant indication is affected by the developer with which it is used. This test method, however, measures the brightness of a penetrant on a convenient filter paper substrate which serves as a substitute for the developer.  
1.3 The brightness measurement obtained is color-corrected to approximate the color response of the average human eye. Since most examinations are done by human eyes, this number has more practical value than a measurement in units of energy emitted. Also, the comparisons are expressed as a percentage of some chosen standard penetrant because no absolute system of measurement exists at this time.  
1.4 The measurements made by this standard compare the brightness of a candidate penetrant to that of a standard penetrant when tested according to the technique. There is no known correlation between the results obtained and the brightness of actual flaw indications obtained using the penetrant in inspection.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 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.
