Foreword
GB/T 16895 "low-voltage electrical installations" is divided into five parts, each part is divided into multiple sub-parts.
--- Part 1. Basic principles, general characteristics assessment and definition;
--- Part 4. Security;
--- Part 5. Selection and installation of electrical equipment;
--- Part 6. Inspection;
--- Part 7. Particular equipment or place requirements.
This section GB/T 16895 "low-voltage electrical installations," Part 4. Security Part 42.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 16895.2-2005 "Electrical installations in buildings - Part 4-42. Protection of thermal protection," and
GB/T 16895.2-2005 compared to the main technical changes are as follows.
Its scope now includes all thermal effects on electrical installations that propagate to other fire barriers adjacent to it and
Flame protection;
--- Added/revised requirements for evacuation routes in case of emergency;
--- Add/modify the processing or storage of the nature of the material requirements;
--- Add/modify the requirements on combustible building materials;
--- Add/modify the flame spread on the structure requirements;
--- Increases the places that may endanger valuables, the choice of its installation and installation of new requirements;
--- Increase the space heating equipment in overheat protection.
This section uses the translation method identical with IEC 60364-4-42.2010 "Low-voltage electrical installations Part 4-42. Safety and thermal protection
Should be protected. "
The documents of our country that are consistent with the corresponding international documents that are normative references in this section are as follows.
