Introduction

JJF 1355-2012 "non-automatic scales (indicating analogue scales) Type Evaluation Outline" Modify adopted OIMLR76- 1.2006, "non-automatic weighing instrument" international recommendations relating to the provisions indicating analogue scales, taking the GB/T 11884- 2008 "Spring dial scale" developed from the relevant technical requirements. Replace JJG555-1996 "non-automatic weighing Universal Test procedures, "the relevant provisions indicating analogue scales. In the preparation of the implementation of the format JJF 1016-2009 "Measuring Instruments Type evaluation outline guidelines for the preparation "requirement. Non-automatic scales (indicating analogue scale) Type Evaluation Outline

JJF 1181-2007 "metrological terminology and definitions", GB/T 14250-2008 "Weighing term" and GB/T 11884-2008 "spring dial scale" in terms apply to this outline. In this paper, the main symbol involved. Max. maximum capacity; Min. minimum capacity; e. verification scale.

4 Overview

Indicating analogue scale is. A spring is a load cell, the scale pointer and dial direct. As spring dial scale and so on. Spring dial scale principle. it is the use of a spring deformed by external force, that it is within the elastic limit of the spring Deformation and Hooke's law and an external force proportional to the work. Spring dial scale structure. mainly by load-bearing means, metering spring means, gear, zero means and shell Composition, in order to reduce the effect of temperature changes on the weighing indication, but also equipped with a temperature compensation device.
