ASTM D6022-19 provides a standardized methodology for calculating the Permanent Shear Stability Index (PSSI) of a lubricant additive. By comparing viscosities before and after a defined shearing procedure, this practice allows formulators to quantify the viscosity loss contributed specifically by…
🧪 Scope and Significance of ASTM D6023-16 This standard test method explains the determination of the density (unit weight) of freshly mixed Controlled Low-Strength Material (CLSM) and provides the gravimetric formulas for calculating the corresponding yield, cement content, and air…
📐 Scope and Applicable Fuel Types ASTM D6021-22 provides a standardized method for measuring the total concentration of hydrogen sulfide (H₂S) in complex fuel matrices. The method is applicable for concentrations ranging from 0.01 to 100 µg/g (ppmw). It specifically…
📜 Standard Overview and Scope ASTM D602-81 (Reapproved 2019) provides the standard specification for barium sulfate pigments, specifically the naturally occurring barytes and the chemically precipitated blanc fixe. This specification is critical for industries such as paints, coatings, plastics, and…
The D6020 −00 (Reapproved 2020) standard practice provides a definitive method for calculating the combined (non-mineral) tanning agents and the degree of tannage in vegetable-tanned leather and leather containing organic retannages. It is essential for quality control and material characterization…
🧪 Purpose and Scope of ASTM D6019-20 ASTM D6019-20, designated as the “Test Method for Determination of Chromic Oxide in Basic Chromium Tanning Liquors (Ammonium Persulfate Oxidation),” provides a definitive procedure for quantifying chromium content in tanning baths. This method…
🔬 Scope and Significance of the Test This test method, designated ASTM D6018-96 (Reapproved 2012), is used for qualitatively determining the presence of lead salts in leather. Lead salts may be present in pigments used during leather manufacture, and this…
🧪 Scope and Significance ASTM D6016-17 (Reapproved 2023) specifies a standard test method for the quantitative determination of water extractable nitrogen in leather. This method identifies nitrogen-containing water extractable materials such as excess and loosely bound tannins, ammonium salts, and…
ASTM D6017-97 (Reapproved 2020) defines a standardized gravimetric test method for the quantitative determination of magnesium sulfate, commonly known as Epsom salt, in leather. This method is specifically designed to distinguish magnesium sulfate from other water-soluble non-tanning salts present in…
📐 Specimen Geometry and Preparation Section 7 of the standard specifies a square of leather approximately 4 in. by 4 in. (102 mm by 102 mm) as the required test specimen. Sampling is conducted strictly per Practice D2813, and conditioning…
