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ASTM D4429 – Standard Test Method for CBR (California Bearing Ratio) of Soils in Place (Withdrawn 2018) Description: Significance and Use Field in-place CBR tests are used for evaluation and design of flexible pavement components such as base and subbase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 …
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 …
