introduction
In.2014, China issued the national standard GB/T 3883.1-2014 "Handheld, portable power tools and garden tools safety
Part 1. General Requirements, the original GB/T 3883 (handheld power tool part), GB/T 13960 (portable power tool part) and
GB/T 4706 (only for garden power tools) is integrated with the common technical requirements of the general safety standards for the three series of power tools.
The specific requirements for the specific types of small products used in conjunction with GB/T 3883.1-2014 are 3 parts, respectively, part 2 (hand
The part of the holding power tool), the third part (portable power tool part), the fourth part (the part of the garden power tool) are all converted to the corresponding country.
Special requirements for the standard IEC 62841 series.
The main elements of the standard name are expanded to “safe for hand-held, portable power tools and garden tools”, using the original hand-held power tools
