5.1 This standard, used in conjunction with a verification protocol can be used to gain certification for the purposes of the removal of trash and/or debris from stormwater runoff in order to meet regulatory and permit needs.1.1 The scope of this standard is to provide test criteria for the evaluation of Stormwater Control Measures (SCM), especially Manufactured stormwater Treatment Devices (MTDs), for the removal of trash and/or debris greater than 5 mm in at least two dimensions in a laboratory setting. The use of this standard in conjunction with an appropriate verification program allows for the publication of verified reporting for use in gaining certification by Authorities Having Jurisdiction (AHJs).1.2 For the purpose of this method, a Trash Capture Device (TCD) is an SCM that has the capacity to capture and retain trash and or debris. This may be the primary objective of the device or it may be a secondary feature of a device designed primarily as a Hydrodynamic Separator (HDS) or a filter for capturing sediment particles. This protocol does not address the sediment removal of such devices.1.3 Units—The values stated in inch-pound units are to be regarded as standard, except for methods to establish and report sediment concentration and particle size. It is convention to exclusively describe sediment concentration in mg/L and particle size in mm or μm, both of which are SI units. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. Reporting of test results in units other than inch-pound units shall not be regarded as non-conformance with this test method.1.4 Acceptance of test results attained according to this specification may be subject to specific requirements set by a Quality Assurance Project Plan (QAPP), a specific verification protocol, or AHJ. It is advised to review one or all of the above to ensure compliance1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 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.

Consistency in analysis depends on being aware of a significant change in instrumental response, such as that caused by drift or changes in analytical precision, or both, and taking corrective action. The usual corrective action for drift is standardization. Standardization, however, when there is no real need, can only broaden the spread of subsequent analyses. One purpose of this practice is to set guidelines that will avoid “unnecessary standardization.” To control manufacturing processes, there must be confidence that a consistent material is being produced and that the analysis of the material is reliable. For assurance that the material meets specification, a purchaser may require the supporting record of control charts to assess that proper analytical control has been maintained. Ideally, variations in analytical results may be held to chance causes. The concept of a confidence interval or limits on a control chart is based on what can be expected when all normal precautions are exercised. When results appear to go out of control, the analyst should consider and correct what might be an assignable cause. As experience is accumulated, however, it may not seem unusual for readings to drift with time as optics degrade, detector response changes, or excitations conditions change, for example, when deposits build up on a counter electrode (a correctable assignable cause), or the longer range effects as an X-ray tube deteriorates.1.1 This practice covers procedures for determining if a spectrochemical analysis is under statistical control. 1.2 Criteria are presented for determining when corrective action is required. 1.3 Control will be effected by using verifiers to test instrument response. It is recommended, although not required, that this be accompanied by the plotting of control charts. 1.4 The preparation of control charts is described. 1.5 Limitations—The procedures that are described do not apply to analyses that require a calibration each time a set of analyses is run. Reference is made specifically to atomic emission spectrometry, but the practice has a more general application. 1.6 This practice does not apply to validation procedures that monitor the correctness of calibration.

4.1 This practice will provide the following: (1) a statistical summary of individual production run data plotted on a control chart; (2) a statistical summary of data from multiple production runs; (3) a procedure to relate the average and variation of these data groups to specification limits, and (4) indexes for comparing different manufacturing units for projecting future capabilities or as historical reference.1.1 This practice covers (1) a statistical procedure for analyzing the test data generated in the statistical process control of a carbon black manufacturing process; (2) a format for reporting process capability determined from the analysis of control chart data of an individual production run, and (3) a format for reporting process performance determined from the analysis of control chart data of an individual production run.1.2 This practice specifically applies to the analysis of pelleted carbon black samples taken during the manufacturing process prior to storage. This practice does not apply to shipment samples taken from hopper cars or other containers or packages.1.3 This practice is specifically designed to be used for those test methods given in Classification D1765 which specify target values. However, these techniques are applicable to other test methods on carbon black.1.4 This practice describes the calculation for two methods of determining capability factors from an analysis of process control data.1.4.1 Process capability (Cp) is a measurement of variation calculated from the process control chart data with the use of an estimated standard deviation (^σ) from the mean value of the moving range (R) chart. The calculation of the process capability (Cp and Cpk) indexes can be used as historical information or to predict future performance of the process, but are only valid when the process is in a state of statistical control.1.4.2 Process performance (Pp) is a measurement of variation calculated from the process control chart data using sample standard deviation(s). The calculation of the process performance (Pp and Ppk) indexes are used for a historical reference of a process' performance and does not require a state of statistical control.1.5 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.

1.1 These test methods cover procedures for the operation of several instruments measuring various properties of cotton fibers; specifically micronaire, color, trash content, length, length uniformity, strength, and fiber elongation. These instruments are connected through a computer communications network and collectively are known as the Motion Control HVI Fiber Information System (See Fig. 1). These methods are applicable to loose cotton fibers taken from raw or partially processed cotton or some types of cotton wastes. 1.1.1 The micronaire reading of loose cotton fibers is determined by measuring the resistance of a "plug" of cotton fibers to air flow under prescribed conditions. 1.1.2 The measurement of length and length uniformity is made by an air flow measuring instrument outputting a voltage directly proportional to the amount of fiber in the prepared specimen at a given distance from the base of the prepared test beard, which is held in a clamp. 1.1.3 The measurements of tensile strength or breaking tenacity and elongation are made by an instrument in which the fibers are clamped between jaws with 1/8-in. (3.2-mm) spacing. A strain-gage device is used to measure breaking force, and a displacement measuring device is used to determine the fiber elongation at breaking load. 1.1.4 The measurement of the color of raw cotton is done by means of a cotton color meter of the Nickerson-Hunter type. It can be used to measure color of any type of raw cotton. 1.1.5 The measurement of the surface trash content of raw cotton is accomplished through optical analysis of the sample by a computer governing the scanning action of the sample through a video camera. 1.2 These test methods may exhibit shifts in the levels of the instrument outputs depending on the stage of processing at which the cotton fiber exists for testing. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only; the conversion may be approximate. 1.4 This standard contains the following sections: Sections 1 Referenced Documents 2 Terminology 3 Sampling 4 Conditioning 5 Micronaire Method 6-11 Length and Length Uniformity Method 12-20 Strength and Elongation Determination Method 21-29 Color and Trash Determination Method 30-34 Calculations 35 Report 36 Precision and Bias 37-39 Keywords 40 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. Specific precautionary statements are given in Note 6 and Section 17.
