1.1 This test method covers quantitatively determining the water extractable nitrogen in leather. 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...
1.1 This fire-test-response standard describes a procedure for measuring the minimum concentration of oxygen, expressed as percent volume, that will just support flaming combustion in a flowing mixture of oxygen and nitrogen. 1.2 This test method provides three testing procedures. Procedure...
This specification covers chromium-molybdenum alloy steel plates for welded broilers and pressure vessels designed for elevated temperature service. Materials considered under this specification are available in grades 2, 12, 11, 22, 22L, 21, 21L, 5, 9 and 91. The steel materials shall be killed...
This specification covers iron-chromium-nickel
4.1 The iodine adsorption number is useful in characterizing carbon blacks. It is related to the surface area of carbon blacks and is generally in agreement with nitrogen surface area. The presence of volatiles, surface porosity, or extractables will influence the iodine adsorption number....
5.1 Cryo-TEM is a technique used to record high resolution images of samples that are frozen and embedded in a thin layer of vitrified, amorphous ice (2-5). Because vitrification occurs so rapidly, the resultant specimen is almost instantly frozen, yielding a very accurate representation of the...
This specification covers general requirements that shall apply to wrought stainless steel bars, shapes, forgings, and billets or other semi-finished materials, except wire, for forging. The materials shall be furnished in one of the following conditions: (1) hot-worked; (2) hot-worked and...
1.1 This test method covers the determination of total nitrogen (TN) and total dissolved nitrogen (TDN) in surface water, seawater, groundwater, wastewater, and wastewater effluents in the range from 0.2?mg/L N to 10?mg/L N. Concentrations from 10?mg/L to 500?mg/L are possible when...
1.1 These test methods cover the chemical analysis of chromium and ferrochromium having chemical compositions within the following limits: Element Composition,?% Aluminum 0.25 max Antimony 0.005 max Arsenic 0.005 max Bismuth 0.005 max Boron 0.005 max Carbon 9.00 max Chromium ??51.0 to 99.5 Cobalt 0...
4.1 Knowledge of the UV transmittance of MEG is required to establish whether the product meets the requirements of its quality specifications. 4.2 Dissolved oxygen in organic solvents, such as MEG, forms complexes that shift the solvent absorption from the vacuum UV range into the measurable UV...
1.1 This test method covers the determination of nitrogen in lubricating oils when present in the concentration from 0.03?% to 0.10?% by mass, and for the determination of nitrogen in fuel oils when present in the concentration from 0.015?% to 2.0?% by mass. This test method is also...
3.1 This test method is used to measure the surface area of precipitated, hydrated silicas that is available to the nitrogen molecule using the multipoint (B. E. T.) method. Single point nitrogen surface area is measured in accordance with the Test Methods D5604. 3.2 Solids adsorb...
This SAE Standard provides the testing and functional requirements guidance necessary for a leak detection device that uses any non-A/C refrigerant tracer gas, such as helium or a nitrogen-hydrogen blend, to provide functional performance equivalent to a refrigerant electronic leak detector....
1.1 This test method is applicable to the determination of nitrate plus nitrite (as nitrogen) in drinking water, surface, saline, wastewater, and ground waters. The applicable range of this test method is from 0.05 to 5 mg/L of nitrogen. The range may be extended upward by dilution of...
1.1 This test method covers the determination of methane, ethane, propane, propene, acetylene, iso-butane, propadiene, butane, trans-2-butene, butene-1, isobutene, cis-2-butene, methyl acetylene and 1,3-butadiene in high-purity ethylene. The purity of the ethylene can be calculated by subtracting...
This specification covers LNG density calculation models for use in the calculation or prediction of the densities of saturated liquefied natural gas (LNG) mixtures at a specified temperature range given the pressure, temperature, and composition of the mixture. Composition restrictions for the...
This specification covers age-hardening stainless steel forgings for general use. Materials for forgings shall consist of billets or bars and shall either be forged, rolled, or cast or a section cut from an ingot. The steel specimens shall be solution annealed and age hardened and shall conform to...
