ASTM D471 – Standard Test Method for Rubber Property—Effect of Liquids Description: Significance and Use 4.1 Certain rubber articles, for example, seals, gaskets, hoses, diaphragms, and sleeves, may be exposed to oils, greases, fuels, and other fluids during service. The exposure may be continuous or intermittent and may occur over wide temperature ranges. 4.2 Properties of rubber …
ASTM D4705 – Standard Test Method for Stitch Tear Strength of Leather, Double Hole Description: Significance and Use 3.1 This test method is designed to measure the load required to tear leather through two holes in the test specimen. Tanners and leather buyers have found that this test gives an indication of the resistance of leather …
ASTM D4704 – Standard Test Method for Tearing Strength, Tongue Tear of Leather Description: Significance and Use 4.1 Knowledge of the strength of the sample can be a determining factor for the end use of the product. Scope 1.1 This test method is intended for determining the tearing strength of leather by measuring the force required to …
ASTM D4703 – Standard Practice for Compression Molding Thermoplastic Materials into Test Specimens, Plaques, or Sheets Description: Significance and Use 4.1 The methods by which sample materials are prepared and molded influence the mechanical properties of the specimen. Unlike injection molding, the objective of compression molding is to produce test specimens or sheets that are both …
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 …
