ASTM D3233 – Standard Test Methods for Measurement of Extreme Pressure Properties of Fluid Lubricants (Falex Pin and Vee Block Methods) Description: Significance and Use 5.1 Evaluations by both test methods differentiate between fluids having low, medium, and high levels of extreme-pressure properties. The user should establish any correlation between results by either method and service …
ASTM D3231 – Standard Test Method for Phosphorus in Gasoline Description: Significance and Use 5.1 Phosphorus in gasoline will damage catalytic convertors used in automotive emission control systems, and its level therefore is kept low. Scope 1.1 This test method covers the determination of phosphorus generally present as pentavalent phosphate esters or salts, or both, in gasoline. …
ASTM D3230 – Standard Test Method for Salts in Crude Oil (Electrometric Method) Description: Significance and Use 5.1 This test method is used to determine the approximate chloride content of crude oils, a knowledge of which is important in deciding whether or not the crude oil needs desalting. The efficiency of the process desalter can also …
ASTM D323 – Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method) Description: Significance and Use 5.1 Vapor pressure is an important physical property of volatile liquids. This test method is used to determine the vapor pressure at 37.8 °C (100 °F) of petroleum products and crude oils with initial boiling point above 0 °C (32 °F). 5.2 Vapor …
ASTM D3228 – Standard Test Method for Total Nitrogen in Lubricating Oils and Fuel Oils by Modified Kjeldahl Method Description: Significance and Use 5.1 The concentration of nitrogen is a measure of the presence of nitrogen-containing additives. Knowledge of its concentration can be used to predict performance. Scope 1.1 This test method covers the determination of nitrogen …
ASTM D3227 – Standard Test Method for (Thiol Mercaptan) Sulfur in Gasoline, Kerosine, Aviation Turbine, and Distillate Fuels (Potentiometric Method) Description: Significance and Use 5.1 Mercaptan sulfur has an objectionable odor, an adverse effect on fuel system elastomers, and is corrosive to fuel system components. Scope 1.1 This test method covers the determination of mercaptan sulfur in …
ASTM D3223 – Standard Test Method for Total Mercury in Water Description: Significance and Use 5.1 The presence of mercury in industrial discharge, domestic discharge, and potable water is of concern to the public because of its toxicity. Regulations and standards have been established that require the monitoring of mercury in water. This test method provides …
ASTM D3218 – Standard Specification for Polyolefin Monofilaments Description: Significance and Use 6.1 Acceptance Testing—The test methods in Specification D3218 for the determination of the properties of polyolefin monofilaments are considered satisfactory for acceptance testing of commercial shipments of polyolefin monofilaments, unless specified in the individual test method. These test methods are the best available and are used …
ASTM D3198 – Standard Test Method for Application and Removal Torque of Threaded or Lug-Style Closures (Withdrawn 2016) Description: Significance and Use These torque measurements are of value in: 5.1.1 Rating the performance of automatic capping machines, 5.1.2 Measuring any tendency for threaded or lug-style closures to loosen during storage or shipment of the package, …
ASTM D3192 – Standard Test Methods for Carbon Black Evaluation in NR (Natural Rubber) Description: Significance and Use 3.1 The major portion of carbon black consumed by the rubber industry is used to improve the physical properties, life expectancy, and utility of rubber products. These test methods provide a natural rubber formulation and directions for evaluating …
