ASTM D1725-12 (Reapproved 2019) is a standard practice that provides detailed instructions for preparing resin solutions intended for viscosity measurement using the bubble time method. This practice ensures consistency in sample preparation, whether for solid resins dissolved in the laboratory…
⚙️ Scope and Normative References ASTM D1719-11 (Reapproved 2019) covers the specification for isobutyl alcohol (also known as 2-methyl-1-propanol and isobutanol). This specification is primarily intended for solvents used in paint, varnish, lacquer, and related coating products. The values stated…
📐 Scope and Terminology The test method quantifies the volume ratio of hydrocarbon diluent to active solvent required to cause persistent heterogeneity (precipitation) in a cellulose nitrate solution. The end point is strictly defined as the maximum number of unit…
ASTM D1721 – 97 (Reapproved 2007) provides a standardized procedure for detecting the presence of oxidizable impurities, notably phenols, in tricresyl phosphate (TCP). This test method is essential for specification acceptance and quality control in the evaluation of plasticizers and…
ASTM D1712-09 (Reapproved 2020) is a standard practice for evaluating the resistance of plastics to sulfide staining. It is crucial for materials containing metallic compounds that may form colored sulfides when exposed to sulfide sources. The practice specifies specimen preparation,…
📐 Scope and Referenced Standards This specification, ASTM D1718 – 09 (Reapproved 2023), defines the requirements for isobutyl acetate (95 % grade), a solvent widely employed in paints, lacquers, and as a chemical intermediate. For determining conformance, all observed or…
📐 Scope and Material Specifications ASTM D1710-15 (Reapproved 2021) is the standard specification for extruded polytetrafluoroethylene (PTFE) rod, heavy-walled tubing, and basic shapes. This specification covers materials manufactured from the virgin PTFE resin defined in Specification D4894, as well as…
📐 Overview of D1711-24 Terminology ASTM D1711-24 is a standard terminology that compiles technical terms used in testing and specifying solid electrical and electronic insulating materials. It serves as a central reference for definitions balloted through Subcommittee D09.94 and the…
📐 Specimen Geometry and Dimensions ASTM D1708-18 defines the tensile testing of plastics using a standard microtensile “dog-bone” specimen. While superseded for general use by D638 (Type V specimen) or D882, it remains the standard for specific material specifications relying…
The ASTM D1709-24 standard specifies two test methods for determining the impact resistance of plastic film by the free-falling dart method. The energy required to cause failure is expressed as the weight (mass) of the dart dropped from a specific…
