But that is a big "IF." If filled to 454 g and 1 lb is claimed, 454 g is the larger claim and is what must be check under the current law. However, many packages are labeled 453 g | 1 lb in which case 1 lb is the larger claim and must be checked.
I don't see that checking only the smaller claim (if it is the metric claim) can be justified. Of course I agree that IF the company fills and claims such that the metric claim is the larger claim, only it needs to be checked. so it can be argued it is completely within the company's control. ________________________________ From: "mechtly, eugene a" <mech...@illinois.edu> To: U.S. Metric Association <usma@colostate.edu> Cc: USMA <usma@colostate.edu> Sent: Thursday, September 18, 2014 11:53 AM Subject: [USMA:54377] Re: NIST Training Course for Checking the Net Amouts inside Packages Ezra, Thanks for the compliment! The current FPLA requires “duality” of labeling. The NIST Handbook 133 (Page 15) requires verification of the “larger of the two declarations." Amendment of the current FPLA is necessary to make metric-only *labeling* a legal reality. However, Metric-Only *Enforcement* of amounts inside packages if already legal (in my opinion) so long as the declaration in units from the SI is the *larger* of the two declarations. Machines that fill packages are not precise to six significant digits. Hence the elaborate procedure of Maximum Allowed Variation (MAV) which allows some packages to contain less that the targeted amount. See Page 3 on MAV in NIST Handbook 133. Gene.
