📐 Specimen Preparation and Test Conditions ASTM D4289-24a evaluates the compatibility of lubricating greases and fluids with elastomeric materials. Test coupons are cut from standard vulcanized elastomer sheets prepared in accordance with Practice D3182. For rubber products not available in…

📜 Purpose and Scope of Standard D4286 The ASTM D4286-08 (Reapproved 2021) standard provides a systematic criteria guide and procedural method for evaluating the qualifications of coating contractors. Specifically designed for light-water nuclear power plants, this practice focuses on the…

📐 Scope and Applicability This test method, designated ASTM D4287-00, determines the viscosity of paints, varnishes, and related products at a constant shear rate of 12,000 s⁻¹. It is applicable to both Newtonian and non-Newtonian fluids. However, paints that dry…

📐 Scope and Terminology This standard, designated D4284–12 (Reapproved 2017), specifies a test method for determining the pore volume distributions of catalysts and catalyst carriers using mercury intrusion porosimetry. The applicable range of apparent pore entrance diameters is typically between…

ASTM D4285-24, formally designated as the Standard Practice for Indicating Oil or Water in Compressed Air, is an essential quality control procedure widely adopted in the surface preparation and coatings industry. Also known simply as the “blotter test,” this method…

🧪 Scope and Application ASTM D4282 – 15 (Reapproved 2022) establishes a standardized test method for the determination of free cyanide in water and wastewater. Under this method, free cyanide is precisely defined as the cyanide species that diffuses as…

🧪 Scope and Principles ASTM D4283 – 98 (Reapproved 2022) is a specialized standard dedicated to the accurate measurement of kinematic viscosity in silicone fluids formulated for polish applications. Developed under the jurisdiction of ASTM Committee D21 on Polishes, this…

ASTM D4280-23 establishes the standard specification for extended life type, nonplowable, raised retroreflective pavement markers. These safety-critical devices are engineered to provide reliable nighttime lane marking and delineation under demanding traffic and environmental conditions. This specification unifies requirements across material…

ASTM D4281-95 (Reapproved 2005) defines the standard test method for determining oil and grease in water and wastewater. The method relies on a gravimetric determination of substances that are extractable by a specific fluorocarbon solvent from an acidified sample. As…

ASTM D4279-95 (Reapproved 2022) provides standardized methods for determining the water vapor transmission (WVT) rates of bulk shipping containers. It defines two distinct procedures — Method A for Reclosable Containers and Method B for Containers Not Designed for Reclosing —…

🧪 Overview and Scope of the Standard Guide ASTM D 4277 – 83 (Reapproved 1998) provides a comprehensive framework for testing heat-reactive nitrogen resins, particularly urea-formaldehyde and melamine-formaldehyde resins. The guide consolidates existing ASTM methods to evaluate the quality, consistency,…

ASTM D4278-02 defines a standard wet ashing practice designed to decompose wood samples, specifically preservative-treated wood, for subsequent inorganic chemical analysis. This procedure prepares the sample for the quantitative determination of arsenic (As), chromium (Cr), copper (Cu), phosphate (P), and…
