ASTM D6915-07 标准参考黑色颜料的炭黑评估用标准实施规程

This practice is intended to ensure that SRBs are produced and evaluated by a standard procedure. This practice is to be used to establish the average physicochemical properties of a set of carbon blacks to be used as SRBs. The carbon black grades to be used as SRBs should be selected to give as much coverage of the typical usage range for each test and as nearly evenly spaced across the range as possible. Typically, the carbon black grades selected consist of three tread (hard) type furnace grades (designated A, B, and C), three carcass (soft) type furnace grades (designated D, E, and F), and one thermal type grade (designated G). Subcommittee D24.61 may elect to carry one or more of the existing SRBs into the next set provided there is enough remaining material at the rate of usage to last through the expected life of the next set. Limiting the choice of grades to be used means that not all tests will have an SRB set that is evenly spaced across the range of interest. All the SRB candidates are produced at approximately the same time by the various producers. They are used as a set once they are approved. The sets are consecutively numbered. Values and identification for the current set are given in Guide D 4821. Any SRBs carried forward will be renumbered for the new set.1.1 This practice covers guidelines for the production and testing for uniformity of a set of carbon blacks to be used as Standard Reference Blacks (SRBs).1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.

Standard Practice for Carbon Black-Evaluation of Standard Reference Blacks

ASTM D4821-07e1 炭黑标准指南 试验方法精度和偏差的验证

One of the major causes of poor test precision is the lack of calibration or standardization of instruments, apparatus, reagents, and technique among laboratories. The sum of all sources of testing error is unique for an individual laboratory. A least-squares regression of a laboratory''s actual test values for reference materials to the established mean values will result in a unique least-squares regression line (and equation) for that laboratory. Generally, there are two reasons for using the SRBs in testing: (1) to monitor testing performance (see Section 4) to ensure that no systematic error or bias is affecting the test results, or (2) to establish a statistical calibration (see Section 5) when the correction of assignable causes (see Section 6) does not yield in-control test results. In addition to the calibration of a test method by physicochemical means, a statistical method for achieving calibration of a test method is presented. This guide outlines the use of control charts to graphically present calibration test data determined for the ASTM SRBs for those test methods given in Section 2. All laboratories are encouraged to utilize statistical control charts and the SRBs because this allows a comparison of testing precision within a laboratory to the “industry average” values found in Table 1, Table 2, or Table 3. The techniques of this guide can be used to continuously monitor testing execution and precision for other tests that are not listed in Section 2 or for materials that fall outside the range of the SRBs for those tests listed in Section 2. In these cases, each laboratory will have to establish the applicable mean and control limit values for the “local reference.” The monitoring will then consist of a comparison of present test results for the “local reference” to past performance within that laboratory instead of to “industry average” values.1.1 This guide covers a procedure for using ASTM Standard Reference Blacks (SRBs) to continuously monitor the precision of those carbon black test methods for which standard values have been established. It also offers guidelines for troubleshooting various test methods. 1.2 This guide establishes the x-chart control limits to be used when continuously monitoring those tests listed in Section 2. Alternatively, these control limits may be used as a basis for comparison to testing precision computed within a laboratory. 1.3 This guide uses statistical control chart methodology as discussed in MNL7 to determine if a laboratory''s test results differ significantly from the accepted values of the SRBs. 1.4 This guide provides a statistical procedure for improving test reproducibility when a laboratory cannot physically calibrate its apparatus to obtain the standard values of the ASTM SRBs, within the ranges given in the precision statement of the test method. 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.

ASTM D1510-07 炭黑—碘吸收值的标准试验方法

The iodine adsorption number is useful in characterizing carbon blacks. It is related to the surface area of carbon blacks and is generally in agreement with nitrogen surface area. The presence of volatiles, surface porosity, or extractables will influence the iodine adsorption number. Aging of carbon black can also influence the iodine number.1.1 This test method covers the determination of the iodine adsorption number of carbon black.1.1.1 Procedure A is the original procedure for this determination.1.1.2 Procedure B specifies an increased sample mass of carbon black and volume of iodine solution (the ratio is the same as in Procedure A) which results in a simplified formula for the calculation of the iodine number.1.2 The iodine adsorption number of carbon black has been shown to decrease with sample aging. New SRB HT Iodine Standards have been produced that exhibit stable iodine number upon aging. These SRB HT Iodine Standards are recommended for daily monitoring (x-charts) of testing and for standardization of iodine testing (see Section ) when target values cannot be obtained.1.3 The values stated in SI units are to be regarded as the standard.

ASTM D1900-06 碳黑.散装装运物抽样的标准实施规程

Sampling of bulk shipments of carbon blacks is of utmost importance since the location and number of samples taken by different laboratories can have a significant effect on the agreement of test values obtained. This practice is for use in obtaining representative samples of carbon black in each compartment or in the entire hopper car or hopper truck. These samples may be used to ascertain the average quality or the uniformity of a shipment, or both.1.1 This practice covers procedures for the sampling and data reporting of bulk shipments of carbon black in three-compartment hopper rail cars and compartmented bulk hopper trailers. Note 1 - The tests to be made on the samples obtained by this practice, how many samples are taken, where they are taken, and what statistical values (if any) to report shall be determined by agreement between the purchaser and the manufacturer. This practice gives guidance for use in developing such agreements or for use when no formal agreement exists. The specific details of each procedure are described in appropriate ASTM test methods used for testing carbon black.Note 2 - Some purchasers or manufacturers may consider Flexible Intermediate Bulk Containers (FIBC) to be a bulk shipment. See Practice D 1799 for guidance on sampling and reporting for this package.12. The values stated in SI units are to be regarded as the standard.

ASTM D4578-06(2012) 橡胶助剂的标准试验方法.萃取法测定硫百分比

Test Method A is commonly used for quality control testing because of the solvent efficiency of carbon disulfide. Test Method B employs toluene as a solvent because it is less toxic and less volatile than carbon disulfide. Test Method B is more likely to be used for research and development or for any other purpose where such information may be useful.1.1 These test methods cover the determination of solvent insoluble materials in a sulfur sample. The two test methods available are: (1) Test Method A, Extraction by Carbon Disulfide, and (2) Test Method B, Extraction by Toluene. If there are no other solvent insoluble materials present in the sulfur, these test methods determine the insoluble sulfur content directly. If other materials are also present, additional testing is necessary to identify what portion of the insolubles is insoluble sulfur. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
