Introduction

This specification based JJF 1071-2010 "National Calibration Specifications writing rules", JJF 1001-2011 "Tong Metering Terms and definitions "and JJF 1059.1-2012" Evaluation and Expression of Uncertainty in Measurement "establishment. The specification for the first time to develop. Reference ballast calibration specifications

1 Scope

This specification applies to the rated frequency of 50Hz, 60Hz and 20kHz ~ 50kHz reference ballast calibration. 2. References This specification refers to the following documents. GB/T 10682-2010 double capped fluorescent lamps - Performance requirements GB/T 14044-2008 requirements for ballasts for tubular fluorescent lamps Performance GB/T 15042-2008 light discharge lamps (excluding tubular fluorescent lamps) - Performance requirements Ballasts GB/T 15144-2009 tubular fluorescent lamps with electronic ballasts performance requirements GB/T 17262-2011 Single-capped fluorescent lamps - Performance requirements Part 13 control unit GB/T 19510.13-2007 lamp. discharge lamps (excluding fluorescent lamps) with a straight Specific requirements for the exchange of electronic ballasts or For dated references, only the dated edition applies to this specification; undated reference documents Member, the latest edition (including any amendments) applies to this specification.

3 terminology and units of measurement

This specification uses the following terms and units of measurement. 3.1 Calibration current calibrationcurrent Calibration and adjustment of the reference ballast is based on the current value; unit. A. Voltage and current ratio 3.2 voltagecurrentratio Current terminal voltage divided by the reference ballast, that the reference ballast impedance; Unit. Ω.

4 Overview

Reference ballast is connected between the power source and the light source, to provide a baseline reference for measuring electrical characteristics of the light source parameters point. Frequency of 50Hz or 60Hz reference ballast is a special design of inductive ballast, by one or Several self-inductance coil, mounted or fitted with an auxiliary resistor; reference frequency of the town of 20kHz ~ 50kHz stream Device is a specially designed ballast resistor, by one or more of a resistor, can be equipped with an appropriate inductance or capacitance. Reference ballast is usually installed in the seal with mechanical, electrical, and magnetic protection housing. Reference ballast according to the assignment into a single value of the reference ballast, multi-valued reference ballast; subjects were divided into fluorescent lamps by Job Reference ballast and high-intensity discharge lamp ballasts reference; according to the working frequency divided reference frequency ballasts, high frequency group Associate ballast, wherein the reference frequency inductive ballasts, high frequency ballast reference was resistive.

5 Metrological characteristics

5.1 voltage and current ratio (impedance) 5.1.1 The ballast voltage reference current ratio (impedance) should be GB/T 10682 or GB/T 17262 Base Light
