  • Maximum Dry Density of Cohesionless Soils by Pluviation and by ASTM D 4253-83: A Comparative Study

    Maximum dry densities of a variety of granular soils, ranging from silty sand to sandy gravel (Dmax = 9.5 mm), were determined by ASTM Test Methods for Maximum Index Density of Soils Using a Vibrating Table (D 4253-83) and by pluviation. The effects of various test conditions during pluviation were also investigated. The pluviation method offers several advantages compared to that of the ASTM ...

  • Comparison of EN 14078 and ASTM D7371 infrared biodiesel methods

    Infrared (IR) analysis is the most widely used measurement technology for measuring biodiesel in diesel. Both EN 14078 and ASTM D7371 methods use infrared as the analytical method and more specifically FTIR (Fourier Transform Infrared) spectroscopy. Infrared is a common spectroscopic technique used for quantitative and qualitative analysis. In the biodiesel measurement, the fatty acid methyl ...

  • New ASTM Test Method Offers Quick and Easy Oil and Grease Measurement for Water and Soil Samples

    Onsite Field Measurement of Oil and Grease A quick and easy field analysis method for determining oil and grease concentration levels is important for both offshore oil platforms and soil remediation sites.. Prior to the Montreal Protocol, infrared (IR) analysis using Freon as an extraction solvent was a widely used field and laboratory method. In 1999, the U.S. EPA promulgated Method 1664A ...

  • Get Comparable ASTM/EN Data for Biodiesel Blend Measurements While Saving Time and Money using Portable IR Analyzers

    Both EN 14078 and ASTM D7371 methods for measuring the percent biodiesel in diesel fuel use infrared analysis as the analytical method and are based around using an FTIR spectrometer which has the capability to do a multitude of analyses besides the biodiesel in diesel measurement. This is great for a laboratory where various biofuels measurements are required. However, if the only measurement ...

  • Using an inter‐laboratory study to revise methods for conducting 10‐ to 42‐d water or sediment toxicity tests with Hyalella azteca

    Studies have been conducted to refine USEPA, ASTM, and Environment Canada standard methods for conducting 42‐d reproduction tests with H. azteca in water or in sediment. Modifications to the H. azteca method include better defined ionic composition requirements for exposure water (i.e., >15 mg/L of chloride and >0.02 mg/L of bromide) and improved survival, growth and reproduction with ...

  • Evaluation of Fill Compaction

    Compaction was evaluated of existing fills at seven sites. The field densities were evaluated with three different techniques. These techniques included: (1) the sand-cone method, ASTM D 1556; (2) the drive-cylinder method, ASTM D 2937; and (3) a smaller version of drive cylinder that was driven manually into the ground. Two comparisons were made: between sand cone and drive cylinder (ASTM D ...

  • Empirical approach for the prediction of cetane number from the FAME composition

    Cetane number is a prime indicator in evaluating the quality of biodiesel fuel in the realm of diesel engines. Standards have been established world wide for cetane number determination, for example, ASTM D 613 in the USA, internationally, the International Organization for Standardization (ISO) standard ISO 5165, etc. These methods are usually arduous and expensive; the values obtained are ...

  • Strain Measurement in HDPE Geomembrane Tensile Tests

    According to ASTM D 638, the tensile strain in an HDPE geomembrane dumbbell specimen subjected to a tensile test should be evaluated using an extensometer that records the elongation of a defined length of the central portion of the specimen. However, the current practice in the United States for HDPE geomembrane quality control and conformance testing consists of following the 1991 NSF standard ...

  • Notched Constant Tensile Load (NCTL) Test for High-Density Polyethylene Geomembranes

    A modification of an old test method, the notched constant tensile load (NCTL) test, is reintroduced to evaluate the stress-cracking performance of high-density polyethylene (HDPE) geomembranes. In this modified test, notched dumbbell-shaped specimens are subjected to a range of constant tensile loads in a 10% Igepal (CO-630) solution at 50°C. The method has been proposed to ASTM and is being ...
