GB/T 14218-2018Electronic lighting control equipment performance parameters and measurement methods (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 14218-1993 "electronic dimming equipment performance parameters and test methods", compared with GB/T 14218-1993 The main technical changes are as follows.

--- Updated the referenced documents in the normative references (see Chapter 2, Chapter 2 of the 1993 edition);

--- Replaced some terms in terms and definitions, and added some terms (see Chapter 3, Chapter 2 of the 1993 edition);

---Modified the content of "divided by control" in the equipment classification (see 4.3, 1993 edition 4.2);

--- Increased the content of the device "divided by installation type" and "divided by work mode" (see 4.1 and 4.4);

--- Revised the performance parameters related to the basic requirements of the dimming equipment (see 6.2, 1993 version 6.2);

--- Increased the noise requirements for distributed dimmers in performance parameters (see 6.2.1d));

--- Added performance parameters in the performance requirements of the protective grounding of dimming equipment (see 6.2.1e));

--- Increased the performance parameters in the shell protection level requirements (see 6.2.1f));

--- Added the performance parameters of the basic requirements of the dimmer, including cabinet temperature rise, short circuit and overload protection device, plug-in knot Table, trigger accuracy, heat dissipation function, electromagnetic compatibility, harmonics, insulation resistance and protection grounding copper bar minimum cross-sectional area requirements table (see 6.2.1);

--- Removed the requirement for input impedance in the performance parameters (see 6.2.5a of the 1993 edition);

--- Added the basic parameters of the digital dimming console in the performance parameters (see 6.2.3);

--- Increased the performance parameters of the dimmer performance parameter table and the dimming console in the performance parameters (see 6.3.1 and 6.3.2);

--- Added performance parameter test for grounding protection, insulation resistance, power frequency withstand voltage (electrical strength), electromagnetic compatibility, harmonics, Dimmer data receiving capability, dimming console refresh frequency experiment, dimming console and dimming cabinet response time experimental parameters Rong (see 7.2.10~7.2.16);

--- Removed the serial transmission content in the performance parameter test (see 7.2.12 of the 1993 edition);

--- Added the content of the measuring instrument (see Chapter 8).
