ASTM D1200 Viscosity By Ford Viscosity Cup
This test method covers the determination of the viscosity of Newtonian or near-Newtonian paints, varnishes, lacquers, and related liquid materials with the Ford-type efflux viscosity cup. If the material is non-Newtonian, that is, shear-thinning or thixotropic, Test Method D2196 should be used.

ASTM D3237 Lead in Gasoline by AAS
The gasoline sample is diluted with methyl isobutyl ketone and the alkyl lead components are stabilized by reaction with iodine and a quaternary ammonium salt. The lead content of the sample is determined by atomic absorption flame spectrometry at 283.3 nm, using standards prepared from reagent grade lead chloride. By the use of this treatment, all alkyl lead compounds give identical response.

Apparatus for Sulfur Content in Petroleum Products
KN-7039 Apparatus for Sulfur Content in Petroleum Products by WDXRF conforms to ASTM D7039 Standard Test Method for Sulfur in Gasoline, Diesel Fuel, Jet Fuel, Kerosine, Biodiesel, Biodiesel Blends, and Gasoline-Ethanol Blends by Monochromatic Wavelength Dispersive X-ray Fluorescence Spectrometry. & ASTM D2622 Standard Test Method for Sulfur in Petroleum Products by Wavelength Dispersive X-ray Fluorescence Spectrometry. The sample is placed in the X-ray beam, and the peak intensity of the sulfur Kα line at 0.5373 nm is measured. The background intensity, measured at a recommended wavelength of 0.5190nm (0.5437nm for a Rh target tube) is subtracted from the peak intensity. The resultant net counting rate is then compared to a previously prepared calibration curve or equation to obtain the concentration of sulfur in mg/kg or mass %.

EN14110 Methanol Content In Fatty Acid Methyle Esters By GC
the sample is heared at 80℃ in a hermetically sealed vial to allow desorption of contained methannol into the gas phase.when equilibrium is reached,a defined part of the gas phase is injected into a gas chromatograph,where methanol is detected with a flame ionisation detector.normally methanol is the only peak in the chromatogram.
