🔬 Scope and Significance of the Test Method ASTM D3234-88 (Reapproved 1999) defines a standardized procedure for determining the abrasion resistance of glossy smooth coatings of petroleum wax or wax-based blends applied to paper and paperboard. The test is designed…
📐 Test Overview and Scope The ASTM D3235-23 standard specifies a precise gravimetric method for determining the solvent extractables in petroleum waxes. This parameter, often referred to as “oil content,” is a critical quality indicator. As outlined in Section 5…
📐 Test Method Scope and Equipment ASTM D3233-24 covers two procedures for evaluating the load-carrying properties of fluid lubricants using the Falex Pin and Vee Block machine. The test involves a rotating steel journal at 290 rpm ± 10 rpm…
📐 Scope and Summary of the Test Method ASTM D3230-19, the Standard Test Method for Salts in Crude Oil (Electrometric Method), determines the approximate chloride concentration in crude oil. The range of concentration covered is 3.5 mg/kg to 500 mg/kg…
🔬 Principle and Summary of the Test Method Standard Test Method D3231-24 (developed under Subcommittee D02.03) provides a procedure for the determination of phosphorus in gasoline. Phosphorus, often found as pentavalent phosphate esters or salts, is detrimental to automotive catalytic…
This standard, D3228-22, defines a modified Kjeldahl method for determining total nitrogen in lubricating oils and fuel oils. It covers specific concentration ranges: 0.03 % to 0.10 % by mass for lubricating oils, and 0.015 % to 2.0 % by…
📜 Standard Overview and Scope ASTM D323-20, the Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method), provides procedures for determining vapor pressure of gasoline, volatile crude oil, and other volatile petroleum products. The Reid vapor pressure is…
📐 Scope and Applicability The ASTM D3227-24 (also designated as IP 342/20) standard specifies a potentiometric method for the determination of thiol (mercaptan) sulfur in a variety of petroleum fuels. It is specifically applicable for measuring mercaptan sulfur concentrations within…
🔬 Scope and Significance of this Test Method ASTM D3224-02 standardizes the determination of water solubility of auxiliary solvents (cosolvents) used with biocides like pentachlorophenol in wood preserving solutions. These solvents formulate high-concentration liquid concentrates for shipment or enhance the…
🛢️ Solvent Composition and Physical Requirements This specification outlines the stringent requirements for low-boiling hydrocarbon solvents formulated to carry oil-borne preservatives, most commonly pentachlorophenol. The base solvent must exhibit a narrow range of physical properties to ensure optimal penetration, drying,…
