GB/T 1146-2009Bubble (English PDF)

Foreword

This standard replaces GB/T 1146-1989 "bubble level." This standard and GB/T 1146-1989 The main differences are as follows:

--- Increased electronic vial term.

--- Increased electronic vial classification.

--- After the inspection rules according to GB/T 2828.1, GB/T 2829 selected by the control parameters have been modified. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee photon science and optics (SAC/TC103) centralized. This standard is drafted by: a light Suzhou Instrument Co., Ltd., Shanghai Polytechnic University. The main drafters of this Standard. Wangjia Ping, Huang Weijia. This standard replaces the standards previously issued as follows:

--- GB 1146-1974;

--- GB/T 1146-1989. Vial

1 Scope

GB/T 1146-2009 is the Chinese national standard on bubble, in the field of image technology. 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 30 September 2009 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 December 2009. Classification: ICS 37.020, CCS N31. 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 vial terms, product classifications, requirements, test methods, inspection rules, signs and packaging. This standard applies to Anping and measuring small angle round and tubular vial.
