ASTM D3866 – Standard Test Methods for Silver in Water Description: Significance and Use 4.1 The principal adverse effect of silver in the body is cosmetic. It causes argyria, a permanent, blue-gray discoloration of the skin, eyes, and mucous membranes. 4.2 Relatively small quantities of silver are bactericidal or bacteriostatic and find limited use in both disinfection …
ASTM D3860 – Standard Practice for Determination of Adsorptive Capacity of Activated Carbon by Aqueous Phase Isotherm Technique Description: Significance and Use 5.1 This practice is used when activated carbon is considered as an adsorbent in treating water. Since both granular and powdered activated carbons are commercially available, a standard practice is needed to ensure that …
ASTM D3859 – Standard Test Methods for Selenium in Water Description: Significance and Use 4.1 In most natural waters selenium concentrations seldom exceed 10 μg/L. However, the runoff from certain types of seleniferous soils at various times of the year can produce concentrations as high as several hundred micrograms per litre. Additionally, industrial contamination can be …
ASTM D3850 – Standard Test Method for Rapid Thermal Degradation of Solid Electrical Insulating Materials By Thermogravimetric Method (TGA) Description: Significance and Use 5.1 Thermogravimetry is useful in determining the dynamic functional effect of temperature on the amount of volatile materials leaving a specimen as the latter is heated progressively to higher temperatures. TGA can be …
ASTM D3849 – Standard Test Method for Carbon Black—Morphological Characterization of Carbon Black Using Electron Microscopy Description: Significance and Use 4.1 Carbon black morphology significantly affects the transient and end-use properties of carbon black loaded polymer systems. A carbon black’s particle size distribution is its single most important property, and it relates to degree of blackness, …
ASTM D3846 – Standard Test Method for In-Plane Shear Strength of Reinforced Plastics (Withdrawn 2024) Description: Significance and Use 5.1 Shear tests of various kinds are widely used in the reinforced plastics industry to assess the strength of the reinforcement-to-resin bond in polyester-, vinyl ester-, and epoxy-resin composites. In addition to their importance for the generation …
ASTM D3838 – Standard Test Method for pH of Activated Carbon Description: Significance and Use 4.1 When a fluid containing an adsorbate is passed through a bed of activated carbon, chemical reactions may take place between the activated carbon, its other noncarbonaceous constituents, and the adsorbate-containing fluid. The pH of the carbon may be a significant …
ASTM D3835 – Standard Test Method for Determination of Properties of Polymeric Materials by Means of a Capillary Rheometer Description: Significance and Use 4.1 This test method is sensitive to polymer molecular weight and molecular weight distribution, polymer stability—both thermal and rheological, shear instability, and additives such as plasticizers, lubricants, moisture reinforcements, or inert fillers, or …
ASTM D3831 – Standard Test Method for Manganese in Gasoline By Atomic Absorption Spectroscopy Description: Significance and Use 5.1 Certain organo-manganese compounds act as antiknock agents when added to gasoline. This test method provides a means for determining the concentration of such a material in a gasoline sample. Scope 1.1 This test method covers the determination of …
ASTM D3829 – Standard Test Method for Predicting the Borderline Pumping Temperature of Engine Oil Description: Significance and Use 5.1 Borderline pumping temperature is a measure of the lowest temperature at which an engine oil can be continuously and adequately supplied to the oil pump inlet of an automotive engine. Scope 1.1 This test method covers the …
