ASTM D4698 – Standard Practice for Total Digestion of Sediment Samples for Chemical Analysis of Various Metals Description: Significance and Use 5.1 The chemical analysis of sediments, collected from such locations as streams, rivers, lakes, and oceans can provide information of environmental significance. 5.2 These practices can be used with either suspended sediment (material actively transported by …
ASTM D4693 – Standard Test Method for Low-Temperature Torque of Grease-Lubricated Wheel Bearings Description: Significance and Use 5.1 This test method differentiates among greases having distinctly different low-temperature characteristics. This test is used for specification purposes and correlates with its precursor which has been used to predict the performance of greases in automotive wheel bearings in …
ASTM D4691 – Standard Practice for Measuring Elements in Water by Flame Atomic Absorption Spectrophotometry Description: Significance and Use 5.1 Elemental constituents in water and wastewater need to be identified to support effective water quality monitoring and control programs. Currently, one of the most widely used and practical means for measuring concentrations of elements is by …
ASTM D4684 – Standard Test Method for Determination of Yield Stress and Apparent Viscosity of Engine Oils at Low Temperature Description: Significance and Use 5.1 When an engine oil is cooled, the rate and duration of cooling can affect its yield stress and viscosity. In this laboratory test, a fresh engine oil is slowly cooled through …
ASTM D4683 – Standard Test Method for Measuring Viscosity of New and Used Engine Oils at High Shear Rate and High Temperature by Tapered Bearing Simulator Viscometer at 150 °C Description: Significance and Use 5.1 Viscosity values at the shear rate and temperature of this test method have been indicated to be related to the viscosity providing …
ASTM D4674 – Standard Practice for Accelerated Testing for Color Stability of Plastics Exposed to Indoor Office Environments Description: Significance and Use 5.1 Tests conducted in accordance with this practice are intended to induce property changes associated with use exposure to light and heat in typical office environments. These exposures are not intended to simulate the …
ASTM D4672 – Standard Test Method for Polyurethane Raw Materials: Determination of Water Content of Polyols Description: Significance and Use 5.1 This test method is suitable for quality control, as a specification test, and for research. The water content of a polyol is important since isocyanates react with water. Scope 1.1 This test method measures the water …
ASTM D4662 – Standard Test Methods for Polyurethane Raw Materials: Determination of Acid and Alkalinity Numbers of Polyols Description: Significance and Use 5.1 These test methods are suitable for quality control, as specification tests, and for research. The acid and alkalinity numbers indicate the extent of a reaction with acids. The results are measures of batch-to-batch …
ASTM D4658 – Standard Test Method for Sulfide Ion in Water (Withdrawn 2024) Description: Significance and Use 5.1 Sulfide ion is found in ground waters and wastewater, causing odor and corrosion problems. If acidified, these waters can release hydrogen sulfide, which is extremely toxic even at low levels. This test method provides a means for interference-free …
ASTM D465 – Standard Test Methods for Acid Number of Pine Chemical Products Including Tall Oil and Other Related Products Description: Significance and Use 3.1 These test methods are designed to broaden the scope of the earlier editions of the test method by the inclusion of tall oil and tall oil derived products as test materials …
