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 ________________ A Numbering system of Chemical Abstracts, Inc. 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 and health 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).

ASTM D4936-10(2015) 采用还原/滴定法进行巯基苯并噻唑亚磺酰胺鉴定的标准试验方法

5.1 This test method is designed to assess the purity of 2-mercaptobenzothiazole sulfenamide accelerators. These products are used in combination with sulfur for the vulcanization of rubber. 5.2 The test method is suitable for assessing product specifications in that the property it measures is related to product performance. Since it is the primary property for comparison of product quality at different production facilities, good interlaboratory accuracy and precision is required. 5.3 Based on past experience, two significant sources of error in this test method are: (1) incomplete reduction and (2) titration end point assessment. Problems in these areas can be avoided by closely following the procedure. 1.1 This test method covers the determination of assay on mercaptobenzothiazole (MBT) sulfenamides. It is based on a titration of the basic amines liberated upon reduction of the sulfenamides with hydrogen sulfide gas (H2S)2 ,3 or 2-mercaptobenzothiazole. 1.2 Any free amine (HNR2) or weak acid salts of the corresponding amine (HX·HNR2) are titrated prior to reduction. This titer is used to calculate percent basic impurity (as free amine) in the sample. 1.3 With the indicated modifications, this test method is applicable to all MBT sulfenamides, that is, N-cyclohexyl-2-benzothiazolesulfenamide (CBS), N,N-diisopropyl-2-benzothiazyl sulfenamide (DIBS), 2 (morpholinothio) benzothiazole (MBS), N,N-dicylohexyl-2-benzothiazyl sulfenamide (DCBS), N-tert-butyl-benzothiazole-sulfenamide (TBBS), and 4-morpholinyl-2-benzothiazyl disulfide (MBSS). 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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. For specific hazard statements, see Section 9.
