5.1 The Federal Occupational Safety and Health Administration, in 29?CFR 1910, designates that certain gases and vapors must not be present in workplace atmospheres at concentrations above specific values. 5.2 This practice will provide a means for the determination of airborne concentrations of...
4.1 Titanium dioxide pigments are components with high refractive index that significantly influence the opacity, color, durability, and other properties of coatings. This test method for determining titanium dioxide content is quicker and easier to use than Test Methods D1394, a wet chemical...
1.1 These test methods cover the determination of the water present in new or unused glycol-based coolant concentrates using a volumetric (Test Method A) or an automatic coulometric titrator procedure (Test Method B). 1.2 Many carbonyl compounds react slowly with the Fischer reagent, causing...
3.1 The iodine value of a fatty acid product is a measure of the unsaturated fatty acid content of that product and consequently a measure of the ease of oxidation or drying capacity of that fatty acid product. 3.2 This test method measures the unsaturation as iodine value by addition of an...
4.1 This test method may be used in quality control laboratories when the repeated analysis of titanium dioxide in similar paints may be required. Reagents and time are kept to a minimum when this test method is used in place of wet chemical analysis such as in Test Methods D1394. However,...
1.1 These test methods cover the chemical analyses of hydraulic cements. Any test methods of demonstrated acceptable precision and bias may be used for analysis of hydraulic cements, including analyses for referee and certification purposes, as explained in Section 4. Specific chemical test methods...
1.1 This practice covers a procedure for estimating the fathead minnow (Pimephales promelas) 96-h LC50 of nonreactive (that is, covalently bonded without unsaturated residues) and nonelectrolytic (that is, require vigorous reagents to facilitate substitution, addition, replacement reactions...
4.1 Materials handling equipment operability and long-term integrity are concerns that originate during the design and fabrication sequences. Such concerns are most efficiently addressed during one or the other of these stages. Equipment operability and integrity can be compromised during handling...
4.1 Control of water content is often important in controlling the performance of paint and paint ingredients, and it is critical in controlling volatile organic compound (VOC) content. 4.2 Paint materials are often insoluble in common Karl Fischer solvents such as methanol. Pyridine has been found...
1.1 This guide is intended to serve as a reference for laboratories wishing to perform 99Tc analyses in soil. Several options are given for selection of a tracer and for the method of extracting the Tc from the soil matrix. Separation of Tc from the sample matrix is performed using an extraction...
1.1 These test methods cover the quantitative determination of dissolved or occluded water present in any proportion in liquid pine chemicals, such as turpentine, pinene, dipentene, pine oil, tall oil, and tall oil fatty acids. Three methods of moisture testing are included. The Karl Fisher...
1.1 This test method covers unirradiated uranium-plutonium mixed oxide having a uranium to plutonium ratio of 2.5 and greater. The presence of larger amounts of plutonium (Pu) that give lower uranium to plutonium ratios may give low analysis results for uranium (U) (1)2, if the amount of plutonium...
1.1 This test method is intended as a screening test to determine if the solids in a paint contain more than 0.5?% lead. The test described barely detects the presence of 0.4?% but gives a definite positive result at the 0.5?% level. Note 1: This test method may be used to detect the presence of...
1.1 This test method provides an indication of the environmental stress crack resistance of plastic tight-head drums as a summation of the effects of container design, resin, manufacturing conditions, field performance, and other factors. 1.2 This test method may be used to evaluate a plastic...
1.1 This test method permits detection, within 16 days, of the potential for deleterious alkali-silica reaction of aggregate in mortar bars. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. When this test method refers to...
5.1 For the middle distillates whose boiling range is between 170?°C and 400?°C by such distillation methods like Test Method D2887, Procedure A can separate and determine the content of total aromatics and total nonaromatics by SPE and GC analysis of the resulting fractions. The determination of...
1.1 This test method covers procedures for testing estuarine or marine organisms in the laboratory to evaluate the toxicity of contaminants associated with whole sediments. Sediments may be collected from the field or spiked with compounds in the laboratory. General guidance is presented in...
This test method covers the apparatus and procedure for the electrometric measurement of oxidation-reduction potential (ORP) in water. The test method described has been designed for the routine and process measurement of oxidation-reduction potential. ORP is defined as the electromotive force...
3.1 Because of the tendency of prestressed titanium alloy parts to crack if heated while in contact with certain chemical reagents, it is necessary to ensure that cleaning and maintenance materials will not initiate stress corrosion of titanium alloys under controlled conditions. For test...
1.1 This test method covers a direct injection ion chromatographic procedure for determining existent and potential inorganic sulfate and total inorganic chloride content in hydrous and anhydrous denatured ethanol and butanol to be used in motor fuel applications. It is intended for the analysis of...
