🧪 Scope and Summary of ASTM D6267 ASTM D6267/D6267M – 13 (Reapproved 2022) provides a standardized method for determining the apparent viscosity of hydrocarbon resins at elevated temperatures. This test is critical for characterizing the flow properties of resins usedā¦
📐 Scope and Significance ASTM D6265-23 describes a standard practice for separating contaminants in polymers using an extruder filter test. It covers the separation of unmolten particles, gels, and impurities that can cause imperfections in final extruded products. The standardā¦
This article provides an overview of ASTM D6263-23, Standard Specification for Extruded Rods and Bars Made From Rigid Poly(Vinyl Chloride) (PVC) and Chlorinated Poly(Vinyl Chloride) (CPVC). This specification covers material, dimensional, and workmanship requirements for extruded rods and bars usedā¦
📐 Specimen Geometry and Support Conditions This test method is designed for flat, square composite plates made from continuous-fiber reinforced polymer matrix composites. The specimen is supported over a circular opening or in a rigidly-backed configuration while a concentrated quasi-staticā¦
📐 Specifications and Classification for PAEK Shapes ASTM D6262-23 establishes requirements for poly(aryl ether ketone) (PAEK) basic shapes manufactured by extrusion, compression molding, or injection molding. PAEK is a family of semi-crystalline thermoplastics with alternating ketone and ether groups inā¦
📐 Scope, Significance, and Key Apparatus ASTM D6260-98 is a standard test method for the gravimetric determination of carbon black in a specific class of weather-stable nylon materials, as defined in Classification System D 4066. Carbon black is an essentialā¦
ASTM D6261-14 (Reapproved 2022) establishes requirements for extruded and compression molded basic shapes—plate, rod, and tubular bar—manufactured from thermoplastic polyester (TPES). This specification is designed for mechanical-grade plastic products used in fabrication of end items or parts, incorporating material, dimensional,ā¦
ASTM D6259-23 establishes a standardized practice for calculating a Pooled Limit of Quantitation (PLOQ) for analytical test methods. Derived from interlaboratory study (ILS) data and standard regression techniques, the PLOQ defines the lower concentration boundary at which numerical results areā¦
🔬 Scope and Applicability This test method, ASTM D6258-17 (Reapproved 2024), defines the procedure for measuring Solvent Red 164 dye concentration in diesel and burner fuels using visible spectroscopy. It is designed for No. 1 and No. 2 grades perā¦
📐 Overview and Scope This specification, ASTM D6256/D6256M-16, covers the fabrication of new wood-cleated shipping boxes with skidded, load-bearing bases. Designed for nonregulated domestic and overseas shipments, these boxes handle loads under 2500 lb [1134 kg] and lengths not exceedingā¦
