Scope

1.1 These test methods cover the determination of chlorine in used oils, fuels, and related materials, including: crankcase, hydraulic, diesel, lubricating and fuel oils, and kerosene, all containing <25% (mass/mass) water.

1.1.1 Bromide and iodide are also titrated and reported on a molar basis as chlorine.

1.2 The entire analytical sequence, including sampling, sample pretreatment, chemical reactions, extraction, and quantification, is available in kit form using predispensed and encapsulated reagents. The overall objective is to provide a simple, easy to use procedure, permitting nontechnical personnel to perform a test in or outside of the laboratory environment in under 10 min. The test method also gives information to run the test without a kit.

1.2.1 Method A is preset to provide a greater than or less than result at 1000 mg/kg (ppm) total chlorine to meet regulatory requirements for used oils.

1.2.2 Method B provides results over a range from 200 to 4000 mg/kg total chlorine.

1.3 For both methods, positive bias will result from samples that contain greater than 3% (mass/mass) total sulfur. While a false negative result will not occur, other analytical methods should be used on high sulfur oils.

1.4 Method B Lower Limit of Quantitation -In the round- robin study to develop statistics for this method, participants were asked to report results to the nearest 100 mg/kg. The lower limit of quantification could therefore only be determined to be in the range from 870 to 1180 mg/kg .

1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific safety statements are given in Section 3.
