This standard is equivalent to the international standard IEC745-2-16 "Safety of hand-held power tools Part 2: Specific requirements for nailing machines| |tt||This standard should be used in conjunction with GB3883.1 "Safety of Handheld Power Tools Part 1: General Requirements" (IEC745-1). This standard lists the changes necessary to change Part 1 into "Safety Requirements for Electric Nailers". 1 Scope of application
Except for the following provisions, this chapter of GB3883.1 applies. 1.1 is changed to:
This standard applies to electric nailing machines (hereinafter referred to as nailing machines). 2 Definition
Except for the following provisions, this chapter of GB3883.1 applies. 2.2.23. Replaced with:
Normal load refers to the operation of the tool with the engaging parts (such as pins, nails and staples) specified in the manufacturer's instructions, which is equivalent to the number of operations per minute or per second indicated on the nameplate. Frequency, the load exerted on a tool during continuous operation on wood or similar materials. Note: The manufacturer can provide specialized devices to simulate normal use. 2.2.101 added:
A nailer is a tool for driving joints (such as dowels, nails, and U-shaped nails) into wood or similar materials. 3 General requirements
This chapter of GB3883.1 applies.
4 General precautions for testing

GB3883.16-93
Except for the following provisions, GB3883 .1 of this chapter applies. 7.1 Modification:
The rated input power or current should not be marked. Increase:
The maximum number of operations per minute or per second should be marked as: "—/min" or "—/s". 7.13 Added:
The instructions should indicate the recommended joint type and size or product number. Nailing machines should come with an instruction manual detailing how to operate the tool safely to minimize the risk of personal injury to the operator and others who may be nearby. bZxz.net

Except for the following provisions, this chapter of GB3883.1 applies. 16.2 Modification:
The first paragraph is changed to:
GB3883.16-93
The tool is subject to normal load requirements, but without joints, and operates intermittently for 24 hours at 1.1 times the rated voltage. , and then run intermittently for 24 hours at 0.9 times the rated voltage.
Note: Be careful to avoid excessive mechanical stress on the tool during no-load operation. For this purpose, the manufacturer can provide special test equipment or provide the necessary instructions for the tool.
During the test, the tools should be lubricated according to the manufacturer's instructions. During the test, it is allowed to replace those mechanical parts that may eventually fail without affecting electrical safety. 17 Abnormal operation
This chapter of GB3883.1 applies.
18 Mechanical hazards
Except for the following provisions, this chapter of GB3883.1 applies. 18.1 Addition:
Nailing machines shall have means to avoid inadvertent starting, and it shall not be possible to continuously eject joints before the operating switch or the nailing interlocking mechanism has first returned to the initial position. Nailing machines for use with joints having a mass greater than 3g or a penetration length greater than 25mm shall be designed such that if the speed of any joint projected into the air at the point leaving the tool is greater than or equal to 15m/s as predicted by the manufacturer, then unless the tool is used A force of 1.25 times the maximum mass or the maximum mass of the tool plus 5N (whichever is greater) presses the tool against the workpiece, otherwise the tool should not operate. Compliance is checked by observation and practical tests in all possible ways of using the tool. 19 Mechanical strength
