and/or Devices - Tentative Code 

Section 5.59. Electronic Livestock, Meat, and Poultry Evaluation Systems 

and/or Devices – Tentative Code 

This tentative code has only a trial or experimental status and is not intended to be enforced. The requirements are 

designed for study prior to the development and adoption of a final Code for Livestock, Meat, and Poultry 

Evaluation Systems and/or Devices. Officials wanting to conduct an official examination of a device or system are 

advised to see paragraph G-A.3. Special and Unclassified Equipment. 

A. Application 

A.1. This code applies to electronic devices or systems for measuring the composition or quality constituents of 

live animals, livestock and poultry carcasses, and individual cuts of meat or a combination thereof for the purpose of 

determining value.

A.2. See also Section 1.10. General Code requirements. 

A.3. This code does not apply to scales used to weigh live animals, livestock and poultry carcasses, and individual 

cuts of meat unless the scales are part of an integrated system designed to measure composition or quality 

constituents. Scales used in integrated systems must also meet NIST Handbook 44 Section 2.20. Scale 

requirements. 

S. Specifications 

S.1. Design and Manufacture. – All design and manufacturing specifications shall comply with American 

Society for Testing Materials (ASTM) International Standard F2342 Standard Specification for Design and 

Construction of Composition or Quality Constituent Measuring Devices or Systems. 

N. Notes 

N.1. Method of Test. – Performance tests shall be conducted in accordance with ASTM Standard F2343 Test 

Method for Livestock, Meat, and Poultry Evaluation Devices. 

N.2. Testing Standards. – ASTM Standard F2343 requires device or system users to maintain accurate reference 

standards that meet the tolerance expressed in NIST Handbook 44 Fundamental Considerations, paragraph 3.2. 

(i.e., one-third of the smallest tolerance applied.)

N.3. Verification. – Device or system users are required to verify and document the accuracy of a device or 

system on each production day as specified by ASTM Standard F2341 Standard Practice of User Requirements for 

Livestock, Meat, and Poultry Evaluation Devices or Systems. 

N.3.1. Official Tests. – Officials are encouraged to periodically witness the required “in house” verification 

of accuracy. Officials may also conduct official tests using the on-site testing standards or other appropriate 

standards belonging to the jurisdiction with statutory authority over the device or system.

T. Tolerances 

T.1. Tolerances on Individual Measurements. – Maintenance and acceptance tolerances on an individual 

measurement shall be as shown in Table T.1. 

Table T.1. 

Tolerances 

Individual linear measurement of a single 

constituent 

∀ 1 mm (0.039 in) 

Measurement of area ∀ 1.6 cm2

 (0.25 in2) 

For measurements of other constituents As specified in ASTM Standard F 2343 

UR. User Requirements 

UR.1. Installation Requirements. 

UR.1.1. Installation. – All devices and systems shall be installed in accordance with manufacturer’s 

instructions.

UR.2. Maintenance of Equipment. 

UR.2.1. Maintenance. – All devices and systems shall be continually maintained in an accurate condition 

and in accordance with the manufacturer’s instructions and ASTM Standard F 2341. 

UR.3. Use requirements. 

UR.3.1. Limitation of Use. – All devices and systems shall be used to make measurements in a manner 

specified by the manufacturer. 

UR.4. Testing Standards. – The user of a commercial device shall make available to the official with statutory 

authority over the device testing standards that meet the tolerance expressed in Fundamental Considerations, 

paragraph 3.2. (i.e., one-third of the smallest tolerance applied). The accuracy of the testing standards shall be 

verified annually or on a frequency as required by the official with statutory authority and shall be traceable to the 

appropriate SI standard.
