The purpose of this document is to provide performance requirements for hydrogen dispensing systems used for fueling 35 MPa heavy duty hydrogen transit buses and vehicles (other pressures are optional). This document establishes the boundary conditions for safe heavy duty...
1.1 This specification defines the minimum fuel quality requirements for gaseous fuels consisting primarily of methane blended with volume fraction of up to 10 % hydrogen (H2) when used as an internal combustion engine fuel. 1.2 This specification defines the criteria for blending...
This specification covers the requirements for brush plating of tin-zinc by electrodeposition.
5.1 This test method is useful in determining the concentration of hydrogen sulfide in gaseous samples and in verifying compliance with operational needs and/or environmental limitations for H2S content. The automated performance operation of this method allows unattended measurement of H2S...
1.1 This test method is for the determination of total carbon and hydrogen in a sample of refuse-derived fuel (RDF). Both carbon and hydrogen are determined in one analysis. This test method yields the total percentages of carbon and hydrogen in RDF as analyzed and the results...
This specification covers the requirements for brush plating of zinc-nickel by electrodeposition.
1.1 This test method covers the determination of assay on mercaptobenzothiazol
1.1 This test method covers the Wiijs procedure for the determination of unsaturation (iodine value) in hydrogenated nitrile rubbers. 1.2 This test method is applicable only to those hydrogenated nitrile rubbers derived from copolymers of acrylonitrile and butadiene. 1.3 Iodine values are reported...
5.1 Sulfur present as mercaptans or as hydrogen sulfide in distillate fuels and solvents can attack many metallic and non-metallic materials in fuel and other distribution systems. A negative result in the doctor test ensures that the concentration of these compounds is insufficient to cause...
1.1 This test method2 covers the detection of hydrogen sulfide in liquefied petroleum (LP) gases. The sensitivity of the test is about 4?mg/m3 (0.15 to 0.2 grain of hydrogen sulfide per 100?ft3) of gas. 1.2 The values stated in SI units are to be regarded as standard. The values given...
This standard describes a test method for evaluating the susceptibility of uncoated cold rolled and hot rolled Ultra High Strength Steels (UHSS) to hydrogen embrittlement. The thickness range of materials that can be evaluated is limited by the ability to bend and strain the material to the...
1.1 This practice covers the sampling of all grades of steel, both cast and wrought, and all types (grades) of cast irons and blast furnace iron for chemical and spectrochemical determination of composition. This practice is similar to ISO?14284. 1.2 This practice is divided into the following...
1.1 This guide provides advice for conducting experiments to investigate the effects of helium on the properties of metals where the technique for introducing the helium differs in some way from the actual mechanism of introduction of helium in service. Techniques considered for introducing helium...
1.1 This practice covers the basic apparatus, procedures, and conditions required to create and maintain the severe wastewater analysis testing apparatus used for testing a protective coating or lining. 1.2 This apparatus may simulate the pertinent attributes of a typical domestic severe wastewater...
1.1 This test method covers an electronic hydrogen detection instrument procedure for measurement of plating permeability to hydrogen. This method measures a variable related to hydrogen absorbed by steel during plating and to the hydrogen permeability of the plate...
5.1 Proton exchange membranes (PEM) used in fuel cells are susceptible to contamination from a number of species that can be found in hydrogen. It is critical that these contaminants be measured and verified to be present at or below the amounts stated in SAE J2719 and ISO 14687 to ensure...
The purpose of this document is to define design, construction, operational, and maintenance requirements for hydrogen fuel storage and handling systems in on-road vehicles. Performance-based requirements for verification of design prototype and production hydrogen storage and...
This test method is for the determination of total sulfur in combustible fuel gases and is applicable to natural gases, manufactured gases, mixed gases, and other miscellaneous gaseous fuels. For the use of barium chloride titration following collection of sulfur dioxide by alternative procedures,...
1.1 This practice is for the determination of total sulfur from gas phase sulfur-containing compounds in high methane or hydrogen content gaseous fuels using on-line/at-line instrumentation. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are...
This specification establishes the requirements for finished parts machined from unplasticized polychlorotrifluoroe
