4.1 Titration techniques using KF reagent are one of the most widely used for the determination of water. 4.2 Although the volumetric KF titration can determine low levels of water, it is generally accepted that coulometric KF titrations (see Test Method E1064) are more...
1.1 This test method covers the determination of assay on mercaptobenzothiazol
This test method is for the determination of total sulfur in combustible fuel gases and is applicable to natural gases, manufactured gases, mixed gases, and other miscellaneous gaseous fuels. For the use of barium chloride titration following collection of sulfur dioxide by alternative...
5.1 New and used petroleum products can contain basic constituents that are present as additives. The relative amount of these materials can be determined by titration with acids. The base number is a measure of the amount of basic substances in the oil always under the conditions of the...
1.1 This test method covers the determination of water from 0?% to 2.0?% mass in most liquid organic chemicals, with Karl Fischer reagent, using an automated coulometric titration procedure. Use of this test method is not applicable for liquefied gas products such as Liquid Petroleum Gas...
1.1 This test method covers a procedure for the assay of 2-mercaptobenzothiaz
5.1 Crude oils and oil sands bitumen contain naturally occurring acidic species. Acidity of crude oil has been implicated in corrosion of distribution and process systems. The relative amount of these materials can be determined by titrating with bases. The acid number is a measure of this amount...
These test methods cover the chemical analysis of sulfonated and sulfated oils. Water by distillation with volatile solvent and moisture and volatile matter by hot-plate shall be tested to meet the requirements prescribed. Titration test, extraction-titration test, and ash-gravimetric...
1.1 This test method covers a procedure for determining the basic constituents in petroleum products in the field or laboratory using a pre-packaged test kit. The test uses a micro-titration resulting in a visual endpoint facilitated by a color indicator. 1.1.1 This test method covers base...
These test methods cover the sampling and chemical analysis of paste, powder, or liquid detergent fatty alkyl sulfates. The different procedure for sampling and chemical analysis of past, powder, or liquid detergent are presented and discussed in details. Distillation test, titration test,...
4.1 Factors governing selection of a method for the determination of uranium include available quantity of sample, sample purity, desired level of reliability, and equipment availability. 4.2 This test method is suitable for samples between 20?mg to 300 mg of uranium, is applicable to fast breeder...

1.1 This test method covers the determination of hardness in water by titration with potentiometric detection via optical sensor. This test method is applicable to waters that are free of chemicals that will complex calcium or magnesium. The lower detection limit of this test method is...
The test method describes the procedure for the direct determination of water concentration in polyol ester and diester based aerospace lubricants by commercially available automated coulometric Karl Fischer titration instruments. The method was validated to cover the water concentration...
1.1 This test method2 is applicable to the measurement of chloride in highly mineralized waters such as oil field brines, seawater, and brackish water. The test method is based upon the titration of chloride with silver nitrate, using a visual indicator. 1.2 Samples containing from 10?mg to...
1.1 This test method covers procedures for the determination of total sulfur in petroleum products including lubricating oils containing additives, and in additive concentrates. This test method is applicable to samples boiling above 177?°C (350?°F). Other sulfur concentrations outside of those...
5.1 Hydroxyl is an important functional group and knowledge of its content is required in many intermediate and end use applications. This test method is for the determination of primary and secondary hydroxyl groups and can be used for the assay of compounds containing them. 5.2 This test method...
5.1 This test method provides for the quantitative determination of total acidity in ethylene glycols by non-aqueous potentiometric titration. The run time for titration of ethylene glycol samples ranges from 5 to 10 min with no sample preparation required. The length of time for a...
1.1 This test method covers the determination of acidic or basic constituents (Note 1) in petroleum products3 and lubricants soluble or nearly soluble in mixtures of toluene and isopropyl alcohol. It is applicable for the determination of acids or bases whose dissociation constants in water are...
