ASTM D1179 – Standard Test Methods for Fluoride Ion in Water Description: Significance and Use 4.1 Simple and complex fluoride ions are found in natural waters. Fluoride forms complexing ions with silicon, aluminum, and boron. These complexes may originate from the use of fluorine compounds by industry. 4.2 Fluoridation of drinking water to prevent dental caries is …
ASTM D1177 – Standard Test Method for Freezing Point of Aqueous Engine Coolants Description: Significance and Use 5.1 The freezing point of an engine coolant indicates the coolant freeze protection. 5.2 The freezing point of an engine coolant may be used to determine the approximate glycol or glycerin content, provided the glycol type is known. Scope 1.1 This …
ASTM D1171 – Standard Test Method for Rubber Deterioration—Surface Ozone Cracking Outdoors (Triangular Specimens) Description: Significance and Use 4.1 Molded or extruded rubber products must withstand the effects of ozone cracking and outdoor weathering for satisfactory use. This test enables a simple comparison of performance to be made under specified test conditions in an outdoor test. …
ASTM D117 – Standard Guide for Sampling, Test Methods, and Specifications for Electrical Insulating Liquids Description: Abstract This guide describes methods of testing and specifications for electrical insulating oils of petroleum origin intended for use in electrical cables, transformers, oil circuit breakers, and other electrical apparatus where the oils are used as insulating, or heat …
ASTM D1169 – Standard Test Method for Specific Resistance (Resistivity) of Electrical Insulating Liquids Description: Significance and Use 4.1 The resistivity of a liquid is a measure of its electrical insulating properties under conditions comparable to those of the test. High resistivity reflects low content of free ions and ion-forming particles, and normally indicates a low …
ASTM D1160 – Standard Test Method for Distillation of Petroleum Products at Reduced Pressure Description: Significance and Use 5.1 This test method is used for the determination of the distillation characteristics of petroleum products, biodiesel, and fractions that may decompose if distilled at atmospheric pressure. This boiling range, obtained at conditions designed to obtain approximately one …
ASTM D1159 – Standard Test Method for Bromine Numbers of Petroleum Distillates and Commercial Aliphatic Olefins by Electrometric Titration Description: Significance and Use 5.1 The bromine number is useful as a measure of aliphatic unsaturation in petroleum samples. When used in conjunction with the calculation procedure described in Annex A2, it can be used to estimate the …
ASTM D1157 – Standard Test Method for Total Inhibitor Content (TBC) of Light Hydrocarbons Description: Significance and Use 4.1 p-tertiary-butylcatechol is commonly added to commercial butadiene in amounts of 50 mg/kg to 250 mg/kg as an oxidation inhibitor. This test method is suitable for use by both producers and users of butadiene within the limitations described in Section 1. …
ASTM D1155 – Standard Test Method for Roundness of Glass Spheres Description: Significance and Use 4.1 The roundness of glass spheres is one measurable aspect relating to their performance as a retroreflective media. The function of this test method is to measure the percent of true spheres as related to compliance with applicable specifications. NOTE 1: This …
ASTM D1152 – Standard Specification for Methanol (Methyl Alcohol) (Withdrawn 2021) Description: Abstract This specification covers methanol (99.85 % grade). The non-volatile matter, odor property, and color property shall be tested to meet the requirements prescribed. Scope 1.1 This specification covers methanol (99.85 % grade). 1.2 The following applies to all specified limits in this standard; for purposes …
