ASTM D4327 – Standard Test Method for Anions in Water by Suppressed Ion Chromatography Description: Significance and Use 5.1 Ion chromatography provides for both qualitative and quantitative determination of seven common anions, F−, Cl−, NO2−, HPO4 −2, Br−, NO3−, and SO4−2, in the milligram per litre range from a single analytical operation requiring only a few millilitres …
ASTM D4326 – Standard Test Method for Major and Minor Elements in Coal Ash By X-Ray Fluorescence Description: Scope 1.1 This test method covers the analysis of the commonly determined major and minor elements in ash from coal using X-ray fluorescence (XRF) techniques. Note 1: Test Method D5016 is used for determination of sulfur. Note 2: Although not included in …
ASTM D4325 – Standard Test Methods for Nonmetallic Semi-Conducting and Electrically Insulating Rubber Tapes Description: Significance and Use 5.1 The physical and electrical properties, including break strength, elongation, dielectric strength, dissipation factor, permittivity, fusion, etc., will vary with temperature and moisture content. Control the temperature and moisture content of the sample for these test methods to …
ASTM D4318 – Standard Test Methods for Liquid Limit, Plastic Limit, and Plasticity Index of Soils Description: Significance and Use 5.1 These test methods are used as an integral part of several engineering classification systems to characterize the fine-grained fractions of soils (see Practices D2487 and D3282) and to specify the fine-grained fraction of construction materials (see Specification D1241). The …
ASTM D4317 – Standard Specification for Polyvinyl Acetate-Based Emulsion Adhesives Description: Abstract This specification covers polyvinyl acetate or polyvinyl acetate copolymer resin emulsion adhesives suitable for use on wood, wood-based substrates, or plastic laminates. This does not cover the group of polyvinyl-based adhesives suitable for bonding flexible films. Adhesives are classified on the basis of …
ASTM D4310 – Standard Test Method for Determination of Sludging and Corrosion Tendencies of Inhibited Mineral Oils Description: Significance and Use 5.1 Insoluble material may form in oils that are subjected to oxidizing conditions. 5.2 Significant formation of oil insolubles or metal corrosion products, or both, during this test may indicate that the oil will form insolubles …
ASTM D4309 – Standard Practice for Sample Digestion Using Closed Vessel Microwave Heating Technique for the Determination of Total Metals in Water Description: Significance and Use 5.1 The analysis of many types of water for metals using flame atomic absorption spectrophotometry, inductively coupled plasma emission spectrophotometry, direct current plasma emission spectrophotometry, or graphite furnace atomic absorption …
ASTM D4308 – Standard Test Method for Electrical Conductivity of Liquid Hydrocarbons by Precision Meter Description: Significance and Use 5.1 The generation and dissipation of electrostatic charge in fuel due to handling depend largely on the ionic species present which may be characterized by the “rest electrical conductivity.” The time for static charge to dissipate is …
ASTM D4305 – Standard Test Method for Filter Flow of Aviation Fuels at Low Temperatures (Withdrawn 2010) Description: Significance and Use The lowest temperature at which aviation fuels remain free of solid hydrocarbon crystals, which may restrict the flow of fuel through filters in an aircraft fuel system, is a key safety parameter in the …
ASTM D4303 – Standard Test Methods for Lightfastness of Colorants Used in Artists’ Materials Description: Significance and Use 5.1 The retention of chromatic properties by a colorant over a long period of years is essential in a work of art. Accelerated exposure simulates color changes that may reasonably be expected. The producer and the user of …
