1.1 This standard practice is intended for low-risk UAS seeking type certification by the Federal Aviation Administration (FAA) under 14 CFR Part 21.17(b) in accordance with the FAA durability and reliability (D&R) means of compliance (MOC). The definition of "low-risk UAS" does not necessarily...
5.1 Low operating temperature fuel cells such as proton exchange membrane fuel cells (PEMFCs) require high purity hydrogen for maximum performance. The following are the reported effects (SAE TIR J2719) of the compounds determined by this test method. 5.2 Carbon...
5.1 The results of this test method may be used to determine nitrogen oxides and carbon monoxide emission concentrations from natural gas combustion at stationary sources. 5.2 This test method may also be used to monitor emissions during short-term emission tests or...
5.1 This test method is intended to provide a tool for assessing whether fuel storage and distribution facilities, or end user fuel tanks, are subject to microbial growth, and to alert fuel suppliers or users to the potential for fuel quality or operational...
This test method covers the determination of nitrogen oxides (NO and NO2), carbon monoxide (CO), and oxygen (O2) concentrations in controlled and uncontrolled emissions from natural gas-fired reciprocating engines, combustion turbines, boilers, and process heaters using portable analyzers...
5.1 This test method provides a measure of the presence of surfactants in aviation turbine fuels. Like Test Methods D2550 and D3602, this test method can detect carryover traces of refinery treating residues in fuel as produced. They can also detect surface active...
1.1 This test method covers the quantitative determination of water in liquefied petroleum gases (LPG) from 1 mg/kg to 250 mg/kg using an online electronic moisture analyzer, also known as an electronic hygrometer or dew point analyzer, in the absence of methanol or other anti-freeze agent....
5.1 Biodeteriogenic microbes infecting fuel systems typically are most abundant within slime accumulations on system surfaces or at the fuel-water interface (Guide D6469). However, it is often impractical to obtain samples from these locations within fuel systems. Although the...
IEC 62282-5-100:2018 covers construction, marking and test requirements for portable fuel cell power systems. These fuel cell systems are movable and not fastened or otherwise secured to a specific location. The purpose of the portable fuel cell...
This part of IEC 62282 covers construction, marking and test requirements for portable fuel cell power systems. These fuel cell systems are movable and not fastened or otherwise secured to a specific location. The purpose of the portable fuel cell...
The purpose of this International Standard is to provide a test procedure to evaluate the performance of islanding prevention measures used with utility-interconnect
This part of IEC 62282 covers operational and environmental aspects of the stationary fuel cell power systems performance. The test methods apply as follows: - power output under specified operating and transient conditions; - electrical and thermal efficiency under specified...
This International Standard defines the design, safety and operation characteristics of gaseous hydrogen land vehicle (GHLV) refuelling connectors. GHLV refuelling connectors consist of the following components, as applicable: - receptacle and protective cap (mounted on vehicle); - nozzle; -...
1.1 This test method covers the determination of the water vapor content of gaseous fuels by the use of electronic moisture analyzers. Such analyzers commonly use sensing cells based on phosphorus pentoxide, P2O5, aluminum oxide, Al2O3, or silicon sensors piezoelectric-type..
This document specifies test procedures for the basic characteristics of performance, reliability and electrical functionality for the battery packs and systems for either high-power or high-energy application. Unless otherwise stated, the test applies to both applications. NOTE 1 -...
