1、Designation: F2342/F2342M 15Standard Specification forDesign and Construction of Composition or QualityConstituent Measuring Devices or Systems1This standard is issued under the fixed designation F2342/F2342M; the number immediately following the designation indicates the yearof original adoption or
2、, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the requirements for designand construction of evalua
3、tion devices or systems for measur-ing composition or quality constituents of live animals, live-stock and poultry carcasses, and individual cuts of meat, or acombination thereof. Examples include, but are not limited, tohalf and whole carcasses, primals, subprimals, and boxed meat.1.2 The values st
4、ated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3
5、This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.2. Referenced Docu

17、 of Units (SI) and other units specifically ap-proved in IEEE/ASTM SI 10 as a unit for use with SI.3.2.11 units of measure, nfor the purpose of thisspecification, the units of measure shall be the InternationalSystem of Units (SI).3.2.11.1 DiscussionSI units are divided into three classes:base units
18、, derived units, and supplementary units.4. Materials and Manufacture4.1 Indicators and Recording ElementsAll evaluation sys-tems or devices shall be provided with an indicating element,and all systems must include a recording element appropriatein design and adequate in amount for purposes of measu
19、ring,training, calibrating, and testing. The recording of measure-ments may be an electronic record. Primary indications andrecorded representations shall be clear, definite, accurate, andeasy to read during normal use and testing of the device.4.2 The minimum character size of all indications neces
20、saryto the measurement process shall be not less than 4 mm andeasy to read under any ambient condition.4.3 Any measuring or evaluation device or system without abuilt-in recording element shall be provided with a communi-cation interface that permits interfacing with a recordingelement.4.4 All measu
21、ring or evaluation devices or systems musteither (1) automatically maintain a ready-to-measure or evalu-ate condition, (2) automatically display a visual indication andrecord a fault condition, or (3 ) provide no indication ofmeasurement or evaluation.5. Physical Properties5.1 Units of Measure:5.1.1
22、 All measuring devices or evaluation systems shallindicate, or record in the appropriate unit of measure for thetechnology applied.5.1.1.1 The value of the smallest unit indicated or recordedshall not exceed 0.05 in. or 1.0 mm for devices providing alinear measurement, or 0.1 % of capacity.5.2 Opera
23、ting Temperature:5.2.1 All measuring devices or systems shall operate withinapplicable tolerance requirements over the normal ambienttemperature range of 10 to 40C 14 to 104F unless markedwith a restricted temperature range. If the temperature range isnarrower than 10 to 40C 14 to 104F, the ambientt
24、emperature at the time of device calibration shall be posted onthe device. If a measuring device or system is marked with arestricted operating temperature range, the minimum operatingtemperature range shall be not less than 30C 54F.5.2.2 A device or system shall not display or record anyusable valu
