——In Mechanical Hazards, Figures 103~106 are introduced, and the static stalling torque measurement is modified (see 19.101; 19.101 in 2012 edition);
——Addition in Construction: "Tools with a maximum output torque greater than 100N.m shall not be provided with a lock-on device." The length of test device in switch installation requirements is modified from "proper length" to "25mm" (see 21.18.1.1; 21.18 in 2012 edition);
——Annex I (Informative) Measurement of Noise and Vibration Emissions is added;
——Table 4 in this part is replaced by Annex K (see K.18.8).
This part shall be used together with GB/T 3883.1-2014 Safety of Motor-operated Hand-held, Transportable Electric Tools and Lawn and Garden Tools - Part 1:General Requirements.
Clauses indicated with "applicable" in this part means that corresponding clauses in GB/T 3883.1-2014 are applicable; for clauses indicated with "replacement" in this part, those in this part shall prevail; for clauses indicated with "modification" in this part, corresponding clauses modified in this part, other than those in GB/T 3883.1-2014, shall prevail, while other contents in this clause is still applicable; for clauses indicated with "addition", not only corresponding clauses in GB/T 3883.1-2014, but also those in this part, shall be met.
This standard was proposed by China Electrical Equipment Industrial Association.
This part is under the jurisdiction of National Technical Committee on Electric Tools of Standardization Administration of China (SAC/TC 68).

3 Terms and Definitions
This chapter of GB/T 3883.1-2014 is applicable, except as follows.
Additional definitions:
3.101
drill
tool equipped with either a typical three jaw chuck or a machine taper, specifically designed to bore holes in various materials such as metal, plastics, wood, etc.
3.102
impact drill
tool equipped with a chuck specifically designed to bore holes in lightweight concrete, brick and other materials, being similar in appearance and construction, to a drill, but which has a built-in percussion system which gives an axial percussion movement to rotating output spindle
Some impact drills have a device for rendering the percussion system inoperative, so that they can be used as a conventional drill.
3.103
diamond core drill
drill designed to be equipped with a diamond core drill bit with or without a liquid system to drill into materials such as concrete or brick
3.104
mixer
a kind of electric tool mixing the coating, putty, mixed marl and similar materials
4 General Requirements
This chapter of GB/T 3883.1-2014 is applicable.
5 General Conditions for the Tests
This chapter of GB/T 3883.1-2014 is applicable, except as follows.
5.17 Addition:
The mass of the tool includes the drill chuck and the auxiliary handle, if any.
6 Radiation, Toxicity and Similar Hazards
This chapter of GB/T 3883.1-2014 is applicable.
7 Classification
This chapter of GB/T 3883.1-2014 is applicable.
8 Marking and Instructions
This chapter of GB/T 3883.1-2014 is applicable, except as follows.
8.1 Addition:
Drills and impact drills shall be marked with the following:
——rated no-load speed, r/min or min-1.
8.3 Addition:
Drills, impact drills and diamond core drills shall be marked with the following:
——maximum capacity of the chuck, mm.
8.14.1 Addition:
The additional safety instructions as specified in 8.14.1.101 shall be given. This part may be printed separately from the “General Power Tool Safety Warnings”.
8.14.1.101 Addition
Drill safety warnings
——Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
Note 1: the above warning applies only to impact drills and is omitted for drills.
——Use the auxiliary handle(s). Loss of control can cause personal injury.
Note 2: the above warning applies only to tools that are provided with auxiliary handle(s).
——Brace the tool properly before use. This tool produces a high output torque and without properly bracing the tool during operation, loss of control may occur resulting in personal injury.
Note 3: the above warning applies only for tools with a maximum output torque greater than 100N.m measured in accordance with 19.101.
——Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
——Do not turn the mixer on or off unless it is located in mixed materials. Failing to do so may result in personal injury.
8.14.2a) Addition:
101) for diamond core drills: maximum diamond core bit diameter, mm;
102) for tools with a average output torque greater than 100N.m measured in accordance with 19.101: instructions on how to brace the tool;
103) for mixers, applicable mixing medium for mixing device shall be specified.
