Foreword

The standard proposed by China Machinery Industry Federation. The standard measuring instrument by the National Standardization Technical Committee (SAC/TC132) centralized. This standard was drafted. Chengdu Tool Research Institute, Mar Precision Instrument (Suzhou) Co., Ltd. The main drafters of this standard. Li Weiguo, Jiang Zhigang, to Tang Jie, Ho Tung Star, Wang. Electronic digital altimeter

1 Scope

GB/T 22094-2008 is the Chinese national standard on height measuring instrument with electronic digital display, in the field of metrology and measurement. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 25 June 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2009. Classification: ICS 17.040.30, CCS J42. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the electronic digital altimeter terms and definitions, types and basic parameters, working conditions, requirements, test methods, inspection party France, marking and packaging. This standard applies to the number of electrons resolution of 0.1µm, 0.2µm, 0.5µm and 1µm, does not exceed the range of 1000mm Height Measuring Instrument (hereinafter referred to as "altimeter").
