ASTM D4046 – Standard Test Method for Alkyl Nitrate in Diesel Fuels by Spectrophotometry (Withdrawn 2019) Description: Significance and Use 4.1 In diesel fuel, the presence of alkyl nitrates such as amyl nitrate, hexyl nitrate, or octyl nitrate causes a higher residue value than observed in untreated fuel, which can lead to erroneous conclusions as to …
ASTM D4045 – Standard Test Method for Sulfur in Petroleum Products by Hydrogenolysis and Rateometric Colorimetry Description: Significance and Use 4.1 In many petroleum refining processes, low levels of sulfur in feed stocks may poison expensive catalysts. This test method can be used to monitor the amount of sulfur in such petroleum fractions. 4.2 This test method …
ASTM D4039 – Standard Test Method for Reflection Haze of High-Gloss Surfaces Description: Significance and Use 5.1 Measured gloss values of specimens depend on the angle of illumination, refractive index of the material, and the geometric distribution of the reflected light. 5.2 Haze is produced by irregularities in the reflecting surface that affect the distribution of flux …
ASTM D4034 – Standard Test Method for Resistance to Yarn Slippage at the Sewn Seam in Woven Upholstery Fabrics (Withdrawn 2001) Description: Scope 1.1 This test method covers the measurement of the resistance to slippage of warp yarns or filling yarns in woven upholstery fabrics, when testing for yarn slippage at the seam.Note 1-This test …
ASTM D4031 – Standard Test Method for Bulk Properties of Textured Yarns Description: Significance and Use 5.1 The values obtained by this test method should not be used to predict similar properties in fabricated structures except in narrow well-defined comparisons, such as 16.7 tex (150-denier) polyester from the same feed yarn merge and textured on the …
ASTM D402 – Standard Test Method for Distillation of Cutback Asphalt Description: Significance and Use 4.1 This procedure measures the amount of the more volatile constituents in cutback asphalt. The properties of the residue after distillation are not necessarily characteristic of the asphalt used in the original mixture, nor of the residue which may be left …
ASTM D4018 – Standard Test Methods for Properties of Continuous Filament Carbon and Graphite Fiber Tows Description: Significance and Use 5.1 The properties determined by these test methods are of value in material specifications, qualifications, data base generation, certification, research, and development. 5.2 These test methods are intended for the testing of fibers that have been specifically …
ASTM D4017 – Standard Test Method for Water in Paints and Paint Materials by Karl Fischer Method Description: Significance and Use 4.1 Control of water content is often important in controlling the performance of paint and paint ingredients, and it is critical in controlling volatile organic compound (VOC) content. 4.2 Paint materials are often insoluble in common …
ASTM D4014 – Standard Specification for Plain and Steel-Laminated Elastomeric Bearings for Bridges Description: Abstract This specification covers bearings, which consist of all elastomer or of alternate laminates of elastomer and steel, when the function of the bearings is to transfer loads or accommodate relative movement between a bridge superstructure and its supporting structure, or …
ASTM D4007 – Standard Test Method for Water and Sediment in Crude Oil by the Centrifuge Method (Laboratory Procedure) Description: Significance and Use 5.1 The water and sediment content of crude oil is significant because it can cause corrosion of equipment and problems in processing. A determination of water and sediment content is required to measure …
