Solvent purity, however, is monitored mainly by gas chromatography, with individual non-standardized tests routinely being used by the associated industry.

To meet these future regulations and the changing requirements of the automotive industry, the composition of gasoline will also be changed and improved. New analytical methods will be developed to accurately test these new fuels. Petroleum-testing laboratories will apply more rapid spectroscopy techniques, faster chromatography methods, and hyphenated analytical techniques capable of measuring multiple parameters in a single analysis.

More precise test methods will be implemented employing smaller sample sizes, less toxic reagents, and fewer calibration materials. The acceptance of alternative test methodologies will expand as government agencies recognize performance-based test methods for fuel analysis.

Despite this limitation, the method has been used widely for diesel fuel due to the lack of a suitable alternative. In the California Air Resources Board issued regulations that limited the aromatic content of diesel fuel sold in California starting in Another approach to the determination of aromatics in middle distillates is high performance liquid chromatography, HPLC , with refractive index RI detection [2 ].

The Institute of Petroleum has standardized this technique as IP ASTM is currently considering this method and may adopt it as a standard. As the name implies, these products are heavier than gasoline but lighter than gas oils. Besides these products, gas turbine fuel, fuel oil heating oil , and some marine fuels are also classified as middle distillates because they have a wide boiling range that overlaps the lighter fuels.

These products have similar properties but different specifications as appropriate for their intended use. Methods for determining physical properties of these products are well established. They are listed in Table 2 and most will not be discussed further. Table 2 also lists methods for elemental analysis of middle distillates. This chapter will focus on compositional analysis of these products.

Because of the number of isomers in this carbon number range see Table 3 , complete speciation of individual hydrocarbons is not possible for middle distillates. Compositional analysis of middle distillates is obtained in terms of hydrocarbon group type totals.

These groups are most often defined by a chromatographic separation or a mass spectral Z-series. ASTM D86 is a low-efficiency, one theoretical plate distillation. This has been adequate for product specification purposes; however, engineering studies require true boiling point TBP data. Use of simulated distillation has been recently reviewed [1 ]. Typically HPLC is used to separate a particular hydrocarbon group saturates, mono-aromatics, di-aromatics and transfer it to a high-resolution GC column that can resolve many of the individual compounds [4,5 ].

These are rather sophisti2The italic face numbers in brackets refer to references at the end of this chapter. Spectrometric Methods Mass spectrometry has been a powerful technique for hydrocarbon-type analysis of middle distillates. It can provide more compositional detail than chromatographic analysis. Hydrocarbon types are classified in terms of a Z-series.

This method requires that the sample be separated into saturate and aromatic fractions before mass spectrometric analysis. I This separation is applicable to diesel fuel but not to jet fuel, since it is impossible to evaporate the solvent used in the separation without also losing the light ends of the jet fuel.

In addition, this method can give the Z series information by carbon number showing how the composition changes with boiling point. Results from this test are not equivalent to mass- or volume-percent aromatics determined by the chromatographic methods. The chromatographic methods determine the mass- or volume-percentage of molecules that have one or more aromatic tings. Any alkyl substituents on the rings contribute to the percentage of aromatics determined by chromatographic techniques.

ASTM D gives the toolpercent of aromatic hydrogen or carbon atoms. Relatively easy to measure physical properties such as density, viscosity, and refractive index have been correlated to hydrocarbon composition. Several examples of this type of correlative methods are listed in Table 2.

In recent years an entirely new class of correlative methods has been developed. These use near-infrared NIR or midinfrared spectra together with sophisticated chemometric techniques to predict a wide variety of properties. Properties such as saturates, aromatics, and freezing point of jet fuel [9 ] and density, viscosity, aromatics, heat of combustion, and cetane index of diesel fuel [10] have been successfully predicted.

The displacement to be used for the evaluation of the ndings is the average displacement indicated by both instruments mounted symmetrically equidistant from the centroid of the cluster as shown in Fig. The device shall be placed on the structural member to allow the sensing element to bear perpendicularly on the anchor or on a contact plate located on the loading plate as shown in Fig.

The structural member shall be at least 1. The structural member will act as a beam if the spacing between reaction supports is greater than the thickness of the member.

Standard Test Methods for

A structural member with a thickness of at least 1. In general, the thickness of the test member shall be equal to the minimum member depth specied by the manufacturer.

The overall size of the test specimen shall only be reduced when the minimum requirements in 6. Conditioning 7. Describe such conditions in detail.

ASTM Standards

Cast-in-place concrete, grout-set, and epoxy-set anchors are some examples of anchorage systems that require provisions for aging or curing. The choice of the controlled conditions shall simulate the conditions under which the anchors will be used.

Testing shall begin only after the test specimens have reached at least an appropriate stable condition with regard to temperature and moisture content.

Static Tests 8. For tests on clusters of anchors, the instrument shall lie on a plane through the axis of the shear loading rod or plate.

Manual on Hydrocarbon Analysis (Astm Manual Series)

An extension of the axis of the shear loading rod or plate shall pass through the centric axis of the cluster of anchors. Test Specimens 6.

The anchors shall be tested at distances equal to or greater than those given in Table 2. The distances in Table 2 are not intended for design of attachments. Table 2 test support requirements are not prohibited from being reduced for bonded anchors with embedments equal to or greater than 20 anchor diameters. For anchors intended to be eld-installed at spacings less than specied in Table 2 in groups of two or more, test at the intended spacings or edge distances per the requirements of 8.

The structural member is not prohibited from being steel-reinforced. The location and orientation of any reinforcement embedded in concrete or masonry members shall be evaluated. This procedure shall also be repeated for each variation in the structural member. Position the loading device in such a way that it is centered over the anchor to be tested.

Provide uniform contact between the surface of the structural member and the support system. In the nal alignment of the support system, ensure that the forces to be applied through the loading rod are perpendicular to the surface of the structural member section.

The amount of torque or pretension applied to the anchor by the attaching nut or locking device shall be uniform for each series of tests. Whenever a loading plate is required in the testing of a cluster of anchors, ensure uniform loading of the individual anchors of the cluster. A reaction bridge is not required along the edge of the structural member if the edge distance is larger than 4 hef in all directions.

Place the loading plate-rod assembly onto the structural member and secure it in place with the appropriate nut or other locking device typically used for the particular anchor installation to be tested. The amount of force exerted on the loading plate by the attaching nut or locking device shall be uniform for each series of tests performed. For tests that require precise anchor load-displacement data for calculating stiffness or assessing proper functioning, the continuous load application method is required.

Plot the initial and 2-min readings of the measurement devices in the form of load-displacement curves. Maintain complete load-displacement records throughout the test or plot after completion of the test. The data records shall include a time record of the beginning and end of each increment of constant load.
