ASTM C1269-97 内置穿过式金属探测器操作灵敏度设置调整的标准规程

1.1 This practice covers a procedure for adjusting the operational sensitivity of in-plant walk-through metal detectors. Performance of this procedure should result with in-plant walk-through metal detectors being adjusted to an initial operational sensitivity setting suitable for performance testing. 1.2 This practice does not set test object specifications or specify specific test objects. These should be specified by the regulatory authority. 1.3 This practice uses information developed by Practice C1270, or an equivalent procedure, which identifies the critical test object (from a specified set of test objects), its critical orientation, and the critical test path through the detection zone. In the case of Practice C1270, the information is found on the detection sensitivity map(s) for each in-plant walk-through metal detector. 1.4 This practice is one of several developed to assist operators of nuclear facilities with meeting the metal detection performance requirements of the regulatory authorities (see Appendix). 1.5 This standard practice is neither intended to set performance levels nor limit or constrain technologies. 1.6 This practice does not address safety or operational issues associated with the use of walk-through metal detectors. 1.7 The values stated in SI units are to be regarded as standards. The values given in parentheses are for information only.

Standard Practice for Adjusting the Operational Sensitivity Setting of In-Plant Walk-Through Metal Detectors

ASTM C1270-97(2003) 内置穿过式金属探测器探测灵敏度标志的标准实用规程

1.1 This standard practice covers a procedure for determining the weakest detection path through the portal aperture and the worst-case orthogonal orientation of metallic test objects. It results in detection sensitivity maps, which model the detection zone in terms related to detection sensitivity and identify the weakest detection paths. Detection sensitivity maps support sensitivity adjustment and performance evaluation procedures (see Practices C 1269 and C 1309). Note 1Unsymmetrical metal objects possessing a primary longitudinal component, such as handguns and knives, usually have one particular orientation that produces the weakest detection signal. The orientation and the path through the detector aperture where the weakest response is produced may not be the same for all test objects, even those with very similar appearance.Note 2In the case of multiple specified test objects or for test objects that are orientation sensitive, it may be necessary to map each object several times to determine the worst-case test object or orientation, or both.1.2 This practice is one of several developed to assist operators of walk-through metal detectors with meeting the metal detection performance requirements of the responsible regulatory authority. (See )1.3 This practice is neither intended to set performance levels, nor limit or constrain operational technologies.1.4 This practice does not address safety or operational issues associated with the use of walk-through metal detectors.1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.1 This standard practice covers a procedure for determining the weakest detection path through the portal aperture and the worst-case orthogonal orientation (Note 1) of metallic test objects. It results in detection sensitivity maps, which model the detection zone in terms related to detection sensitivity and identify the weakest detection paths. Detection sensitivity maps support sensitivity adjustment and performance evaluation procedures (see Practice C1269). Note 1-As used in this practice, orthogonal orientation refers to alignment of the longitudinal axis of a test object along the XYZ axes of the Cartesian coordinate system; is horizontal and across the portal, is vertical, and is in the direction of travel through the portal. Note 2-Unsymmetrical metal objects possessing a primary longitudinal component, such as handguns and knives, usually have one particular orientation that produces the weakest detection signal. The orientation and the path through the detector aperture where the weakest response is produced may not be the same for all test objects, even those with very similar appearance. Note 3-In the case of multiple specified test objects or for test objects that are orientation sensitive, it may be necessary to map each object several times to determine the worst-case test object or orientation, or both. 1.2 This practice is one of several developed to assist operators of walk-through metal detectors with meeting the metal detection performance requirements of the responsible regulatory authority. 1.3 This practice is neither intended to set performance levels, nor limit or constrain operational technologies. 1.4 This practice does not address safety or operational issues associated with the use of walk-through metal detectors. 1.5 The values stated in SI units are to be regarded as the standard.

1.1 This practice covers evaluation of an optical emission vacuum spectrometer to analyze carbon and low-alloy steels. It covers instruments used for the analysis of solid samples taken from molten metal for production control or from products to confirm the composition. Both pre-installation and post-installation precision and accuracy are included in the evaluation. 1.2 While are specific for plain carbon and low-alloy steel, they could be supplemented by similar tables for other materials.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.
