Foreword
GB/T
16895 "Low-Voltage Electrical Installations" is divided into 5 parts, and each part is divided into multiple sub-parts:
---Part 1: Evaluation and definition of basic principles, general characteristics;
---Part 4: Security Protection;
---Part 5: Selection and installation of electrical equipment;
---Part 6: Inspection;
---Part 7: Requirements for special devices or places:
This part is GB/T
Part 6 of 16895:
This part is in accordance with GB/T
Drafting of the rules given in 1:1-2009:
This part replaces GB/T
16895:23-2012
"Low-Voltage Electrical Installation Part 6: Inspection", and GB/T
16895:23-2012
In comparison, the main technical changes are as follows:
---Modified normative reference documents (see 6:2,:2012 edition 6:2);
---Added 3 items of preliminary inspection regulations (see 6:4:2:3);
---Modified the test sequence (see 6:4:3:1, 61:3:1 of the:2012 edition);
---Added more details in the general provisions of periodic inspection (see 6:5:1);
--- Added Table A:1 (see Appendix A) for the specific resistance value of copper conductors;
--- Deleted the example of the simplified diagram of the original Appendix D on the voltage drop evaluation (see Appendix D of the:2012 edition);
--- Deleted the original Appendix E recommendations for electrical equipment that have been reused in electrical installations (see Appendix E of the:2012 edition):
The translation method used in this part is equivalent to the IEC
60364-6:2016 "Low-Voltage Electrical Installation Part 6: Inspection":

Low-voltage electrical installations Part 6: Inspection
6:1 Scope
GB/T
This part of 16895 gives the initial inspection and periodic inspection requirements for electrical installations:
Through inspection and testing, Chapter 6:4 gives the requirements for the initial inspection of electrical installations, as far as possible to determine GB/T
16895
Whether the relevant requirements of other parts of the company have been met, and put forward the requirements for the initial inspection result report: Upon completion of new installations or existing installations
After the restructuring and expansion are completed, the initial inspection will be carried out:
Chapter 6:5 gives periodic inspections of electrical installations to ascertain as far as possible whether the installation and all its supporting equipment meet the requirements for use:
And the requirements for periodic inspection results reporting:
