ASTM D445 – Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity) Description: Significance and Use 5.1 Many petroleum products, and some non-petroleum materials, are used as lubricants, and the correct operation of the equipment depends upon the appropriate viscosity of the liquid being used. In addition, the viscosity …
ASTM D4449 – Standard Test Method for Visual Evaluation of Gloss Differences Between Surfaces of Similar Appearance Description: Significance and Use 5.1 Gloss3 is associated with the capacity of a surface to reflect more light in some directions than in others. The directions associated with mirror (or specular) reflection normally have the highest reflectances. Gloss is best …
ASTM D4444 – Standard Test Method for Laboratory Standardization and Calibration of Hand-Held Moisture Meters Description: Significance and Use 4.1 Hand-held meters provide a rapid means of sampling MC of wood-based materials during and after processing to maintain quality assurance and compliance with standards. These measurements are influenced by actual MC, a number of other wood …
ASTM D4442 – Standard Test Methods for Direct Moisture Content Measurement of Wood and Wood-Based Materials Description: Significance and Use 4.1 Moisture content is one of the most important variables affecting the properties of wood and wood-based materials. The procedures in these test methods are structured to permit the full range of use from fundamental research …
ASTM D4441 – Standard Specification for Aqueous Dispersions of Polytetrafluoroethylene Description: Abstract This specification establishes the properties and test methods for aqueous dispersions of polytetrafluoroethylene (PTFE) resins, and is used to determine if a shipment, lot, or container of PTFE dispersions is suitable for its intended use. These resins are homopolymers of tetrafluoroethylene, or in …
ASTM D4440 – Standard Test Method for Plastics: Dynamic Mechanical Properties Melt Rheology Description: Significance and Use 5.1 This test method provides a simple means of characterizing the important rheological properties and viscosity of thermoplastic polymers using very small amounts of material (approximately 25 to 50 mm in diameter by 1 to 3 mm in thickness …
ASTM D4438 – Standard Test Method for Particle Size Distribution of Catalysts and Catalyst Carriers by Electronic Counting Description: Significance and Use 4.1 This test method can be used to determine particle size distributions for material specifications, manufacturing control, and research and development work in the particle size range usually encountered in fluidizable cracking catalysts. Scope …
ASTM D4434 – Standard Specification for Poly(Vinyl Chloride) Sheet Roofing Description: Abstract This specification covers flexible fiber- or fabric-reinforced sheet made from poly(vinyl chloride) resin as the primary polymer intended for use in single-ply roofing membranes exposed to the weather. The sheet shall contain. In-place roof system design criteria such as fire resistance, material compatibility, …
ASTM D4429 – Standard Test Method for CBR (California Bearing Ratio) of Soils in Place (Withdrawn 2018) Description: Significance and Use Field in-place CBR tests are used for evaluation and design of flexible pavement components such as base and subbase course and subgrades and for other applications (such as unsurfaced roads) for which CBR is …
ASTM D4423 – Standard Test Method for Determination of Carbonyls in C4 Hydrocarbons Description: Significance and Use 4.1 The determination of the carbonyl content of polymerization-grade 1,3-butadiene is necessary, since in some polymerization reactions, the presence of carbonyls in excess over some specified amount can have a deleterious effect upon the polymer properties or the reaction …
