In addition to complying with the corresponding provisions of GB/T 3883.1-2014, it must also comply with the additional provisions of this document.

In.2014, my country issued GB/T 3883.1-2014 "Safety of hand-held and portable power tools and garden tools - Part 1.

General Requirements", the original GB/T 3883 (hand-held power tools), GB/T 13960 (portable power tools) and GB/T 4706

(Garden power tools only) The common technical requirements of the general safety standards of the three major series of power tools have been integrated.

The special requirements for specific types of small products used in conjunction with GB/T 3883.1-2014 are divided into three parts, namely Part 2 (hand

Part 3 (Hand-held power tools), Part 3 (Part movable power tools), Part 4 (Part 4 (Garden power tools)), are all converted into corresponding

Specific requirements of the 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 will be used.

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

Indicates the corresponding part, and the 2nd and 3rd digits indicate different small categories of products.

The new version of GB/T 3883 series standards will form a more scientific, complete, universal and unified series of safety standards for power tool products

The system makes the implementation of standards more feasible and easy to use.

At present, the new version of GB/T 3883 series standards "Handheld Power Tools Part" has released the following standards.
