📐 Scope and Applicability ASTM D4230-20 describes a standardized test method for determining the thermodynamic dew- or frost-point temperature of ambient air by condensing water vapor on a cooled surface. This temperature is referred to as the condensation temperature for…
📐 Overview and Key Terminology This standard practice, designated D4227-05 (Reapproved 2023), provides a standard qualifying method for coating applicators to verify their proficiency and ability to attain the required quality for application of specified coatings to concrete surfaces. It…
📋 Scope and Classification of Styrene-Butadiene Sheeting ASTM D4225-03 covers styrene-butadiene sheeting in thicknesses of 0.25 mm [0.01 in.] and greater. This material is specifically intended for use in instrument housings and applications requiring resistance to impact, where fabrication methods…
📐 Specimen Types and Conditioning These test methods are specifically designed to evaluate the impact resistance of rigid poly(vinyl chloride) (PVC) building products. The scope of D4226-19 covers rigid PVC plastic sheeting, profile flat sections (e.g., window lineals, siding), and…
📐 Test Method and Scope This test method, designated D4222-20, covers the determination of nitrogen adsorption and desorption isotherms of catalysts and catalyst carriers at the boiling point of liquid nitrogen. A static volumetric measuring system is employed to collect…
ASTM D4223/D4223M −20 establishes the standardized practices for the selection, proportioning, and fabrication of test specimens for asphalt-stabilized soils. The standard specifically covers the preparation of 100 mm [4 in.] diameter by 65 mm [2.5 in.] high cylindrical test specimens…
📐 Scope and Classification of Soil Sample Groups ASTM D4220/D4220M-14 establishes standard practices for preserving and transporting soil samples immediately after field acquisition. The standard uniquely categorizes samples into four distinct groups based on the intended end use and the…
ASTM D4221-18 establishes a standard double hydrometer method for evaluating the natural dispersive characteristics of clay soils. This test is critical for geotechnical engineering applications where soil-water interaction can lead to internal erosion and structural failure. It works by directly…
📐 Scope and Specification Basis ASTM D4219-22 provides a standardized method for determining the short-term unconfined compressive strength index of chemically grouted soils. The specific text establishes that the test utilizes a displacement-controlled application of load. This method is deeply…
🛠️ Scope and Required Apparatus ASTM D422-63 (Reapproved 2007) establishes a standard test method for the quantitative determination of the distribution of particle sizes in soils. The methodology is dual-phase: mechanical sieving for particles retained on the No. 200 (75…
