1.1 This is a high-performance liquid chromatographic (HPLC) test method applicable to the determination of certain n-methylcarbamoyloximes and n-methylcarbamates in ground water and finished drinking water (1 ) .2 This test method is applicable to any carbamate analyte that can be hydrolyzed to a primary amine. The following compounds have been validated using this test method: Analyte Chemical Abstract Services Registry Number A Aldicarb 116-06-3 Aldicarb sulfone 1646-88-4 Aldicarb sulfoxide 1646-87-3 Baygon 114-26-1 Carbaryl 63-25-2 Carbofuran 1563-66-2 3-Hydroxycarbofuran 16655-82-6 Methiocarb 2032-65-7 Methomyl 16752-77-5 Oxamyl 23135-22-0 1.2 This test method has been validated in a collaborative round-robin study (2 ) and estimated detection limits (EDLs) have been determined for the analytes listed in 1.1 (Table 1 ). Observed detection limits may vary between ground waters, depending on the nature of interferences in the sample matrix and the specific instrumentation used. 1.3 This test method is restricted to use by, or under the supervision of, analysts experienced in both the use of liquid chromatography and the interpretation of liquid chromatograms. Each analyst should demonstrate an ability to generate acceptable results with this test method using the procedure described in 12.3 . 1.4 When this test method is used to analyze unfamiliar samples for any or all of the analytes listed in 1.1 , analyte identifications should be confirmed by at least one additional qualitative technique. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Additional guidance on laboratory safety is available and suitable references for the information are provided (3- 5 ) . 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
