📐 Scope and Significance of the Stain Index Test This standard, ASTM D2746/D2746M‑18 (Reapproved 2023), covers the determination of the staining tendency of asphalt and the assignment of a Stain Index proportional to the extent of staining observed. The method…

📐 Overview and Scope ASTM D2749-22 establishes standard symbols for dimensions of pipe fittings made of plastic materials. It provides a comprehensive list of letter designations with definitions, accompanied by drawings of typical fittings to illustrate dimension placements. This standard…

📐 Scope and Applicability These practices (ASTM D2743‑68) provide general information on instrumental techniques, including infrared and ultraviolet spectroscopy and gas chromatography, for detecting adulteration or nonuniformity in traffic paint vehicle solids. The procedures are applicable when traffic paint is…

🔬 Test Method Overview This test method describes the procedure for determining the relative tinting strength of white pigments by reflectance measurements of black tints. It is applicable only when comparing a test pigment with a reference standard of the…

🔬 Introduction and Scope This standard, designated ASTM D2739-97 (Reapproved 2017), defines a precise test method for evaluating the volume resistivity of cured, resin-based conductive adhesives. The measurement is performed directly on a thin adhesive layer as it would exist…

📋 Overview and Scope ASTM D2741-95 (Reapproved 2005), formally titled “Standard Test Method for Susceptibility of Polyethylene Bottles to Soot Accumulation,” establishes a controlled laboratory procedure for evaluating the relative tendency of polyethylene bottles to accumulate soot particles. The standard…

📋 Scope and Material Classification ASTM D2737-22 is issued under the fixed designation D2737 and covers polyethylene (PE) plastic tubing in outside diameters and Standard Dimension Ratios (SDRs) pressure rated for water. The specification defines requirements for PE compounds, workmanship,…

📐 Scope and Specimen Geometry ASTM D2732-14 (Reapproved 2020) defines the standard procedure for determining the unrestrained linear thermal shrinkage of plastic film and sheeting. This test method is specifically applicable to materials with a thickness of 0.76 mm (0.030…

🧪 Summary of Test Method and Core Principle ASTM D2734-23 provides standard test methods for determining the void content of reinforced plastics and composites. The fundamental principle relies on a density-based comparison approach. The densities of the individual constituents (the…

The ASTM D2729-21 standard specifies requirements for poly(vinyl chloride) (PVC) sewer pipe and fittings for non-pressure, gravity-flow drainage systems outside buildings. It covers materials, dimensions, workmanship, chemical resistance, and joint tightness for solid and perforated pipe. 🏗️ Scope and Applications…

ASTM D2731-21 provides a definitive methodology for determining the elastic properties of “as produced” elastomeric yarns, including rubber, spandex, and other elastomers. Operating specifically with Constant-Rate-of-Extension (CRE) tensile testing machines, this standard captures critical hysteresis-related data points such as force…

ASTM D2726/D2726M – 21 establishes the standard procedure for determining the bulk specific gravity (Gmb) and density of non-absorptive compacted asphalt mixtures. Administered by ASTM Subcommittee D04.21, this method is a cornerstone test for asphalt mixture design, production quality control,…
