Introduction

In.2014, my country issued the national standard GB/T 3883.1-2014 ``Safety No. of Handheld and Portable Power Tools and Garden Tools''

Part 1.General Requirements, the original GB/T 3883 (part of hand-held power tools), GB/T 13960 (part of portable power tools) and

The common technical requirements of the general safety standards for the three major series of electric tools in GB/T 4706 (only for garden power tools) have been integrated.

There are 3 parts in the special requirements for specific types of small products that are used in conjunction with GB/T 3883.1-2014.

Portable power tools part), part 3 (portable power tools part), and part 4 (garden power tools part), all transform the corresponding country

The specific requirements of the international standard IEC 62841 series.

The main element of the standard name is expanded to "safety of hand-held, portable power tools and garden tools", and the original hand-held power tools are used

Part of the standard number GB/T 3883.The standard sub-part number of each sub-category product consists of three digits, of which the first digit

Indicates the corresponding part, the 2nd and 3rd digits indicate different subcategories.
