## Foreword

This handbook compiles the latest Uniform Laws and Regulations and
related interpretations and guidelines adopted by the National
Con­ference on Weights and Measures, Inc. (NCWM). At the 1983 Annual
Meeting, the NCWM voted to change the title of Handbook 130 and the
titles of the Laws and Regulations compiled in this handbook. The former
title of the handbook was \"Model State Laws and Regula­tions.\" \"Model
State\" was to be changed to \"Uniform\" in the titles to reflect that
these Laws and Regu­lations are (a) intended to be standards rather than
just guidelines, and (b) intended for adoption by political sub­divisions
other than States when deemed appropriate.

The compilation itself was endorsed by the NCWM in 1979. This edition
includes amend­ments approved at the Annual Meeting in 2002. The
Conference recommends adoption and promulgation by weights and measures
jurisdictions of these Uni­form Laws and Regu­lations as updated in this
handbook.

The National Institute of Standards and Technology has a statutory
responsibility for \"co­oper­a­tion with the States in securing uniformity
of weights and measures laws and methods of inspec­tion.\"  In partial
fulfillment of this respon­sibility, the Institute is pleased to publish
these recom­men­dations of the National Con­ference.

This handbook conforms to the concept of primary use of the
International System of Units (SI) recommended in the Omnibus Trade and
Competitiveness Act of 1988 by citing SI units before customary units
where both units appear together and placing separate sections
containing requirements for SI units before corresponding sections
containing requirements for customary units. In some cases, however,
trade practice is currently restricted to the use of customary units;
therefore, some requirements in this handbook will continue to specify
only customary units until the Conference achieves a broad consensus on
the permitted metric units.
