Instructions
Scale Type Evaluation
AUTOMATIC HOPPER SCALES
Block I. Information about the scale tested .
This block supplies basic background and contact information so that NMFS can maintain accurate contact
records.
Name and mailing address of scale manufacturer
Name, mailing address (if different from manufacturer), telephone and FAX number
of manufacturer’s representative
Model and serial number of scale submitted for evaluation.
Block II. Information about all scales.
More than one model of scale may be evaluated at the same time. However, the models may differ from the
model submitted for evaluation only in the elements of the scale that perform motion compensation, the size
or capacity of the scale, and the software used by the scale. If other elements differ, a separate application
must be completed.
Model Designation: Enter the model name or number that will be visible to the scale inspector and will
allow him to clearly determine that the scale he is inspecting is on the list of approved scales.
Maximum capacity: Report in kilograms.
Value of scale divisions: Enter the smallest division displayed by the scale.
Number of scale divisions: Is the maximum capacity divided by the value of scale divisions.
Minimum Weighment: This must not be less than 20 percent of the maximum capacity or less than 100
scale intervals (except the final weighment of a lot).
Minimum Totalized Load: This may not be less than 4 weighments, and should be reported in
kilograms.
Block III. Information about the certifying laboratory
Information about the laboratory which performed the laboratory evaluation and type testing. The
laboratory must be accredited by the government of the country in which testing was conducted.
Name of laboratory
Mailing address, telephone and FAX of laboratory
Name and Address of Government Agency accrediting the laboratory

Block IV. Certification of compliance
This block is to certify that the manufacturer’s representative believes the scale or scale component is in
compliance with regulations at 50 CFR 679 as indicated in the checklist and test report forms.
Signature and printed name of representative. Enter name and signature of person responsible
for evaluation of the scale
Date of signature
Block V. List of attachments
This block is a checklist of attachments intended to help the manufacturer’s representative include the
correct documentation that NMFS needs to approve the scale. The information provided must be
sufficient to allow NMFS to judge whether the scale is appropriate for its intended use on a vessel at-sea.
Requirements for motion compensation are specifically described in Appendix A, section 2.3.2.6.
Each scale listed in Block II must be described.
Written description and diagrams of the scale indicating primary features of the scale, how the scale
operates, and how the scale compensates for vessel motion.
Describe the difference between the scale submitted for laboratory evaluation and all other scales for
which the laboratory evaluation will apply.
Laboratory test results: Verification of test results that a scale meets the laboratory evaluation and
testing requirements in appendix A to 50 CFR part 679 and each of the influence quantity and
disturbance tests as specified in the annex to appendix A that:
Led to an International Organization of Legal Metrology (OIML) certificate of conformance or
Demonstrates that the scale meets all test requirements in Appendix A or the annex to Appendix
A of 50 CFR 679.28. An National Type Evaluation Program (NTEP) certificate will be accepted
only for the specific influence factor tests which were conducted to receive the NTEP certificate
additional information must be submitted to verify compliance with the laboratory tests that are
not performed under the NTEP.
List of adjustments. Enter a list of types of scale adjustments that will be recorded on the audit trail,
including the name of the adjustment as it will appear on the audit trail, and a written description of
the adjustment. An audit trail in the form of an event logger must be provided to document changes
made using adjustable components.
Other.
This should include any supporting information that will assist NMFS in determining if the scale
meets the performance and technical standards.
Block VI. General Requirements checklist
This checklist is provided for your own convenience and does not need to be submitted to NMFS. Each
item on this list is required before a scale may be approved by NMFS. For each item on the checklist,
there is a reference to a paragraph of Appendix A to 50 CFR 679.28 (attached). If the scale being
evaluated meets that criterion, place a mark in the plus column. If a scale does not meet the criterion, or
you are not certain whether it meets the criterion, place a mark in the minus column.
