Content | L&R Committee 2009 Interim Report Appendix C – Handbook 133 Revisions notes, and other information as needed. This handbook provides random and standard packaged products model inspection report forms in Appendix E, “Model Inspection Report Forms.” Refer to Appendix E for sample instructions to the complete the forms box numbers. Modify the model reports and the box numbers to meet your agency’s needs. Other formats that contain more or less information may be acceptable. Note: Inspection reports should be legible and complete. Good recordkeeping practices typically include record retention for a specified period of time (e.g., 1 to 3 years). Record the product identity, packaging description, lot code, location of test, and other pertinent data. Record the labeled net quantity of contents in Box 1. Record both metric and inch-pound declarations if they are provided on the package label. Example: If the labeled weight is 453 g (1 lb), record this in Box 1. When the declaration of net quantity on the package includes both the International System of Units (SI) (metric) and inch-pound units, the larger of the two declarations must be verified. The rounding rules in NIST Handbook 130, “Uniform Packaging and Labeling Regulations” permit packers to round declarations up or down based on their knowledge of their package filling targets and the accuracy of packaging equipment. Determine the larger of the values by converting the SI declaration to inch-pound units, or vice versa, using conversion factors that are accurate to at least six places. Compare the values, and use the larger value in computing the nominal gross weight (see later steps). Indicate on the report which of the declarations are being verified when packages labeled with two units of measure are encountered. Example: If the net weight declared on a package is 1 lb, the metric equivalent (accurate to six significant digits) is 453.592 g. Do not round down or truncate values in the calculations until the nominal gross weight is determined and recorded. If the package is also labeled 454 g, then the metric declaration is larger than the inch-pound declaration and should be used to verify the net contents of the package. The Basic Test Procedure does not prohibit the use of units of weight instead of dimensionless units when recording package errors, nor does it prohibit the use of net content computer programs to determine product compliance. Record the unit of measure in box 2. The unit of measure is the minimum division of the unit of measurement used to conduct the test. If a scale is used that reads to thousandths of a pound, the unit of measure is 0.001 lb even if the scale division is 0.002 lb or 0.005 lb. Example: If the scale has a scale division of 0.5 g, the unit of measure is 0.1 g. If a weighed package that has an error of “- 0.5 g,” record the error as “- 5” using “dimensionless units.” If the scale indicates in increments of 0.002 lb, the unit of measure is 0.001 lb. If a weighed package has an error of “+0.016,” record the error as “+ 16” using “dimensionless units.” When using dimensionless units, multiply package errors by the unit of measure to obtain the package error in weight. Enter the appropriate MAV value in box 3 for the type of package (weight, volume, etc.), the labeled net contents, and the unit of measure. L&R - C15 |
