ASTM D4422 – Standard Test Method for Ash in Analysis of Petroleum Coke Description: Significance and Use 4.1 The ash content is one of the properties used to evaluate petroleum coke and indicates the amount of undesirable residue present. Acceptable ash content varies with the intended use. Scope 1.1 This test method covers the determination of the …
ASTM D4419 – Standard Test Method for Measurement of Transition Temperatures of Petroleum Waxes by Differential Scanning Calorimetry (DSC) Description: Significance and Use 5.1 DSC in a convenient and rapid method for determining the temperature limits within which a wax undergoes during transitions. The highest temperature transition is a solid-liquid transition associated with complete melting; it …
ASTM D4417 – Standard Test Methods for Field Measurement of Surface Profile of Blast Cleaned Steel Description: Significance and Use 5.1 The height of surface profile has been shown to be a factor in the performance of various coatings applied to steel. For this reason, surface profile should be measured prior to coating application to ensure …
ASTM D4414 – Standard Practice for Measurement of Wet Film Thickness by Notch Gages Description: Significance and Use 4.1 Wet film thickness measurements of coatings applied on articles can be very helpful in controlling the thickness of the final dry coating, although in some specifications the wet film thickness is specified. Most protective and high performance …
ASTM D4404 – Standard Test Method for Determination of Pore Volume and Pore Volume Distribution of Soil and Rock by Mercury Intrusion Porosimetry Description: Significance and Use 5.1 This test method is intended for use in determining the volume and the volume distribution of pores in soil and rock with respect to the apparent diameter of …
ASTM D4402 – Standard Test Method for Viscosity Determination of Asphalt at Elevated Temperatures Using a Rotational Viscometer Description: Significance and Use 5.1 This test method is used to measure the apparent viscosity of asphalts at handling, mixing, or application temperatures. 5.2 Some asphalts may exhibit non-Newtonian behavior under the conditions of this test method, or at …
ASTM D4400 – Standard Test Method for Sag Resistance of Paints Using a Multinotch Applicator Description: Significance and Use 4.1 Evaluation of sag resistance is essential in quality control for both producers and purchasers of coatings. Practical application tests are poor in reproducibility, while viscometric methods, for example Test Methods D2196, are time-consuming and lack the convincing …
ASTM D4383 – Standard Specification for Plowable, Raised Retroreflective Pavement Markers Description: Abstract This specification covers a type of plowable, retroreflective, raised pavement marker for lane marking and delineation. Retroreflective markers are intended for nighttime visibility. Markers shall be classified as to type, color, and intended application. The types of markers are: type A, type …
ASTM D4382 – Standard Test Method for Barium in Water, Atomic Absorption Spectrophotometry, Graphite Furnace Description: Significance and Use 5.1 Barium ranks about sixth in order of abundance in nature; however, it is normally found in only trace quantities in drinking water. Consumption, inhalation, or absorption of 500 to 600 mg is considered fatal to human …
ASTM D4378 – Standard Practice for In-Service Monitoring of Mineral Turbine Oils for Steam, Gas, and Combined Cycle Turbines Description: Significance and Use 4.1 This practice is intended to assist the user, in particular the power-plant operations and maintenance departments, to maintain effective lubrication of all parts of the turbine and guard against the onset of …
