GB/T 15478-2015Test methods of the performances for pressure transducer/sensor (English PDF)

Foreword

The standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 15478-1995 "Test methods of the performance for pressure transducer/sensor". As compared with GB/T 15478-1995, the main changes of this standard are as follows: -In

3.1.2 and 3.1.3, MODIFY the relative humidity to "30% ~ 85%", and MODIFY the deviation range to "± 5%"; -CANCEL the clause

3.2 dynamic conditions from the original standard; - Respectively determine the indicators in 3.3.1b),

3.3.3 as 1/3, 1/5 and 1/5; -In 5.3.2b), with respect to the output impedance, DIVIDE the sensor circuit into passive circuit and active circuit, with corresponding test methods; -In 5.4.2.4, MODIFY the hysteresis definition to "Hysteresis is, at the same test point, the maximum absolute value of the output difference when the measured value increases and decreases"; -In 5.4.2.5, MODIFY the repeatability definition to "Repeatability is the consistency between successive measurement results"; -REMOVE the two indicators "zero drift" and "overload (overload)"from the static performance indicators, both of which are listed as independent items; - CHANGE the "sensitivity stability" to "full scale output stability"; -In 5.6.2b), MODIFY the "... 5 to 10 times the dynamic performance of the sensor." to "... 5 times the dynamic performance of the sensor."; -In 5.9.2.1,CONDUCT detailed descriptions against the "temperature effect test", making specific requirements; MODIFY the "thermal sensitivity drift" to "thermal full-scale output drift"; MODIFY the "thermal sensitivity lagging" to the "thermal full scale output lagging"; MODIFY the "conduct three measurement upper and lower calibration cycles" to the "conduct one measurement upper and lower calibration cycle (only one cycle is measured)"; Test methods of the performances for pressure transducer/sensor

1 Scope

GB/T 15478-2015 is the Chinese national standard on test methods of the performances for pressure transducer/sensor, 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 10 December 2015 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 2016. 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 test conditions, the general provisions of the test, the test items and the test methods, AND data calculation and processing for the performance of the pressure sensor (abbreviated as sensor). This standard applies to pressure sensors (including absolute pressure sensor, differential pressure sensor, gauge pressure sensor AND negative pressure sensor).
