GB/T 16838-2021Environmental test and severities for fire electronic products (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document replaces GB/T 16838-2005 "Environmental Test Methods and Severity Levels of Fire Electronic Products", and is compatible with GB/T 16838-2005 In comparison, in addition to structural adjustments and editorial changes, the main technical changes are as follows.

--- Change the classification of severity levels from the original 4 levels to 5 levels (see 4.3.1, 3.3 in the 2005 edition);

---Modified high temperature (operation) test, high temperature (endurance) test, low temperature (operation) test, low temperature (endurance) test, constant damp heat (operation) Test, constant damp heat (endurance) test, alternating damp heat (operation) test, alternating damp heat (endurance) test, water test, voltage fluctuation resistance Disturbance test, voltage sag, short-term interruption and voltage change immunity test, electrostatic discharge immunity test, radio frequency electromagnetic field radiation Radio immunity test, electrical fast transient pulse group immunity test, surge (impact) immunity test and radio frequency field induced conducted disturbance Interference immunity test (see 5.1~5.8, 5.18~5.25, 4.1~4.8, 4.14~4.19 and 4.21 of the 2005 edition);

---Added new requirements for the safety integrity level of fire-fighting electronic products (see 4.2);

--- Added free drop test, mildew test, salt spray test, sand dust test, power frequency magnetic field immunity test, AC power port harmonic Low-frequency immunity test items of wave, interharmonic wave and power grid signal (see 5.14, 5.15, 5.16, 5.17, 5.26, 5.27).
