GB/T 1226-2017General pressure gauge (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 1226-2010 "general pressure gauge." This standard GB/T 1226-2010 "general pressure gauge" compared to editorial changes in addition to the main technical differences are as follows:

--- For the direct installation of the meter connector length requirements made changes (see 4.3.4,.2010 Edition 4.3.4);

--- Modify the pressure gauge overpressure requirements (see 5.8,.2010 version 6.3);

--- Increased high-pressure gauges alternating pressure requirements and test methods (see 5.9.2,6.11.2);

--- Increased high pressure gauge overpressure test method (see 6.10);

--- Modify the working environment vibration test method (see 6.14,.2010 version 6.12). This standard is proposed by the China Machinery Industry Federation. This standard by the National Institute of Industrial Process Control and Automation Standardization Technical Committee (SAC/TC124) centralized.

1 Scope

GB/T 1226-2017 is the Chinese national standard on general pressure gauge, 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 29 December 2017 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 July 2018. Classification: ICS 17.100, CCS N11. 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 terms and definitions of general pressure gauge, product classification, technical requirements, test methods, inspection rules and signs, packaging and Storage requirements. This standard applies to the spring tube (C-shaped tube, coil spring, spiral tube) for the elastic components of the mechanical pointer pressure gauge, vacuum gauge and pressure Vacuum gauge (hereinafter referred to as instrument).

Note. This standard includes stainless steel pressure gauge and the shell is a special pressure gauge.
