ASTM D3616 – Standard Test Method for Rubber—Determination of Gel, Swelling Index, and Dilute Solution Viscosity Description: Significance and Use 4.1 These tests are particularly useful for quality control in the production of synthetic rubbers. 4.2 Percent gel is a measure of the amount of insoluble rubber present in the chosen solvent. Gel may be introduced intentionally …
ASTM D3612 – Standard Test Method for Analysis of Gases Dissolved in Electrical Insulating Oil by Gas Chromatography Description: Significance and Use 5.1 Oil and oil-immersed electrical insulation materials may decompose under the influence of thermal and electrical stresses, and in doing so, generate gaseous decomposition products of varying composition which dissolve in the oil. The …
ASTM D3611 – Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes Description: Significance and Use 5.1 This practice accelerates the natural aging of pressure-sensitive tapes so that the response to the usual physical property tests changes to the same extent as with an exposure to approximately two years of natural aging when compared with the response …
ASTM D3606 – Standard Test Method for Determination of Benzene and Toluene in Spark Ignition Fuels by Gas Chromatography Description: Significance and Use 5.1 Knowledge of the concentration of benzene may be required for regulatory use, control of gasoline blending, and/or process optimizations. Scope 1.1 This test method covers the quantitation in liquid volume percent of benzene …
ASTM D3605 – Standard Test Method for Trace Metals in Gas Turbine Fuels by Atomic Absorption and Flame Emission Spectroscopy Description: Significance and Use 5.1 Knowledge of the presence of trace metals in gas turbine fuels enables the user to predict performance and, when necessary, to take appropriate action to prevent corrosion. Scope 1.1 This test method …
ASTM D3603 – Standard Test Method for Rust-Preventing Characteristics of Steam Turbine Oil in the Presence of Water (Horizontal Disk Method) Description: Significance and Use 5.1 Horizontal metal surfaces, on which water droplets tend to be retained, are more prone to rusting and corrosion than vertical or sloping surfaces. This test method is therefore more discriminating …
ASTM D36 – Standard Test Method for Softening Point of Bitumen (Ring-and-Ball Apparatus) Description: Significance and Use 4.1 Bitumens are viscoelastic materials without sharply defined melting points; they gradually become softer and less viscous as the temperature rises. For this reason, softening points must be determined by an arbitrary and closely defined method if results are …
ASTM D3597 – Standard Performance Specification for Woven Upholstery Fabrics—Plain, Tufted, or Flocked Description: Significance and Use 4.1 Fabrics intended for this end-use should meet all of the requirements listed in Table 1. (A)For guideline purposes see 6.4.1. (B)Class in the colorfastness requirements is based on a numerical scale of 5 for negligible for no color change or …
ASTM D3590 – Standard Test Methods for Total Kjeldahl Nitrogen in Water Description: Significance and Use 4.1 These test methods are useful for measuring organic nitrogen and ammoniacal nitrogen, which are essential growth nutrients. 4.2 Nitrogen compounds are widely distributed in the environment. Sources of nitrogen include surface-applied fertilizers, cleaning products, and drinking water treatment aids. Because …
ASTM D3588 – Standard Practice for Calculating Heat Value, Compressibility Factor, and Relative Density of Gaseous Fuels Description: Significance and Use 5.1 The heating value is a measure of the suitability of a pure gas or a gas mixture for use as a fuel; it indicates the amount of energy that can be obtained as heat …
