Determination by ASTM Method

Plash and fire poiats, Gardner color, kinematic viscosity, and pour poiats are determined by ASTM methods ... 

Step 1 Molecular weight determination by ASTM method. 

S.P. = Smoke point in millimeters as determined by ASTM Method D1322... 

Elemental analysis of the minus 60-mesh coal was performed using ASTM methods D3177, D3178, and D3179 (15-17). Moisture and ash were determined by ASTM methods D3173 and D3174 (18,19), volatile matter by... 

Assay Determine by ASTM Method E 412-93, Assay of Liquid Chlorine (Zinc Amalgam Method). ... 

Mercury Determine as directed under Mercury Limit Test, Appendix IIIB, testing the Sample Preparation prepared as follows Transfer 2.0 mL of the Sample Solution into a 50-mL beaker, add 10 mL of water, 1 mL of 1 5 sulfuric acid, and 1 mL of a 1 25 solution of potassium permanganate, cover the beaker with a watch glass, boil for a few seconds, and cool. Moisture and Residue Determine by ASTM Method E 410-92, Moisture and Residue in Liquid Chlorine. ... 

Table III summarizes the most important physical-mechanical properties, as determined by ASTM methods, of high impact PS and PVC with EPDM type C elastomer contents of 10% and 9.2% respectively (see Experimental section above for preparative techniques). These products are characterized in Table IV.

To measure the validity of the EPM technique coals were chosen in which sulfate sulfur as determined by ASTM methods equaled zero and in which pyritic sulfur was minimal as determined by ASTM methods and as observed by optical microscopy. Since inorganic sulfur contents are small, any discrepancies between EPM and ASTM organic sulfur contents due to inaccurate pyrite or sulfate analysis also should be small. As can be seen in Table II the EPM analyses very closely approach those of the ASTM. 

A number of laboratory tests are used to predict chemical stabihty. The amount of existent gum in a gasoline is determined by ASTM D381. This method involves evaporating a sample by a jet of heated air. The residue is weighed, solubles are extracted with / -heptane, and the sample is reweighed. 

Apparent equivalent weight deterrnined by titration with hydrochloric acid. APHA color determined by ASTM D1209, platinum—cobalt method. 

Refractoriness. Refractoriaess is determined by several methods. The pyrometric cone equivalent (PCE) test (ASTM C24) measures the softening temperature of refractory materials. Inclined trigonal pyramids (cones) are formed from finely ground materials, set on a base, and heated at a specific rate. The time and temperature (heat treatment) requited to cause the cone to bend over and touch the base is compared to that for standard cones. 

Flammable liquid A liquid having a closed-cup flash point below 100°F (37.8°C) and having a Reid vapor pressure not exceeding 40 psia (2068.6 mm Hg) at 100°F (37.8°C), as determined by ASTM D 323, Standard Method of Test for Vapor Pressure of Petroleum Products (Reid Method).

For example, carbon content can be determined by the method designated for coal and coke (ASTM D3178) or by the method designated for municipal solid waste (ASTM E777). There are also methods designated for ... 

Flash point The flash point is defined as the minimum temperature at which a substance releases ignitable flammable vapors in the presence of an ignition somce, e.g., spark or flame. Flash points may be determined by two methods Tag closed cup via American Society for Testing and Materials (ASTM) method D56 or Cleveland open cup via ASTM method D93. Unless otherwise noted, all... 

Select the engine coolant or antirust with care to ensure adequate corrosion protection. Use only those products conforming to recognized standards such as ASTM D 3306 for engine coolant. Additionally, if your vehicle engine contains major cast aluminum components, be certain the engine coolant meets the heat rejection corrosion limits in ASTM specification D 3306 as determined by ASTM Test Method for Corrosion of Cast Aluminum Alloys in Engine Coolants Under Heat-Transfer Conditions (D 4340). 

The gasoline specification ASTM D-4814 requires gasoline which is marketed and sold to possess a minimum level of resistance to oxidative degradation. This resistance is determined by test method ASTM D-525 and is outlined below ... 

Table 9 shows the classification system for blacks most commonly used in mbber. The ASTM numbering system is based on the fundamental particle size of the black. Particle size is determined by several methods, including iodine absorption, nitrogen absorption, and light scattering.
