There are hand-held power tools and portable power tools according to their operation methods. The safety performance requirements of the two are also different. The International Electrotechnical Commission <1EC\SC6F Subcommittee\Safety of Electric Tools\ has formulated the IEC60745 series of safety standards for hand-held power tools and the IEC6102 series of safety standards for portable power tools, and they have been adopted as equivalent to the GH3883 series standards and the GB13360 series standards respectively. , is the safety certification standard for various handheld and portable power tools. With the human's attention to the protection of the natural environment, the use of electric tools for gardening has developed rapidly. The International Conference on Electrical Engineering has determined the special requirements for electric lawn mowers with pedestrian control.
IFC:SC6:F is the sub-technical committee of the 61st Technical Committee "Safety of Household and Similar Electrical Appliances" engaged in the formulation of safety standards for power tools, including electric tools and other small products. Because the first version of 1E03351001 has been equivalently adopted by 4735.1-1S, when part of it is equivalent to 16033292, the general requirements are partly in GR470F.1-1938. 1 Standard

20.103.2 Flying object hazards
In the expected convenience, the station transmission of the call equipment should provide sufficient protection to prevent the coffee from the rotating light foreign matter falling to the kidney flying with a small amount of foreign matter near the price required test:
The following test shall be carried out.
Place the device in the test pressure room specified in the record AA. The pressure increases as described. The structure used shall be checked by the tests contained in Appendix AA.2 which shall be carried out before and after this test. It shall be divided into sections with horizontal lines as shown in Figure AA.1 and in Appendix CC. The projectile used in the test shall be of diameter .5 and a steel ball with a hardness of at least 4 HR. If a steel ball projectile is used, the injection point shall be set at 12 o'clock and positioned on the top circle of the ejection device as shown in Figures AA.2 and AA.3, and positioned horizontally. For multiple ejection devices, one injection point shall be set for each ejection device. The outlet of the ejection tube shall be located so that it is flush with the upper surface of the fiber surface layer of the shell (see Appendix BB, 3B.1). The system shall be configured so that the steel ball can be ejected at a constant speed. If necessary, the machine may be secured at the bottom of the machine to prevent horizontal movement. During the test, the machine shall be operated at the maximum operating speed of the motor (specified in 2,117). For parts that are not allowed to run frequently or frequently, the machine shall be tested in various working modes. Note: The test personnel shall enter the test area with a small amount of effort and stand at a high altitude. The shovel and drag device shall be adjusted to: when it is on a hard horizontal surface, it can just touch the ground and sweep. Before the test, adjust the ball spraying capacity according to the pressure of the ball on the top of the well. The ball is placed on the top of the well with a lead weight line: 0\ The range is less than 100 meters. After understanding the situation of its position, one copper ball is shot into the machine at a time, and the steel ball is added in small increments until each ball part of the machine is passed. The test is started after it is determined that the product has been lowered. The calcium ball that is cracked or damaged shall be replaced.
During each test, 50 pellets are shot into the target area. For multi-shot equipment, each axis should be tested and the results of each test should be calculated. If during any test there is excessive deviation in a local section, it may be necessary to replace or repair the plate before continuing the test. If the hole left by the previous test cannot be covered by a 40m square label, the plate should be replaced. On any part, do not put on the glue mark completely. Before the test, the steel ball (on the test surface) can be removed by the test personnel to minimize rebound. If necessary, the European and African excavated disk wood medical projectile will be damaged by the impact. Otherwise, the test quality will be unsatisfactory. The number of hits shall be counted and recorded on the data sheet shown in Appendix C. Projectiles hitting the damage climbing area and the distance line shall be recorded as the target area below this line.
For the shovel width 6Um and above, each weapon test <5 (core required projectiles) should hit the target area from 450m to the target area without missing the target. The projectiles above the board (upper vertical x) should not hit the target. When controlling the target area forward from the 450mm line, the hit should not be more than 2 meters. For the case where the width of the shovel joint is greater than 600m, the number of bullets hitting the conveying surface to the load plate (lower and vertical area) in each test (50 bullets) should be no less than 50, of which no more than 6 bullets are hit in the plate above 3m (vertical area). In addition, the bullets hitting the working area between the bottom surface and 1mm above the 1m line (vertical area) should not exceed 2 bullets in a test failure. It can be seen that the test is carried out with all tools, and both devices must pass the test. 20.103.3 The shovel and digging device of the control device, the discharge structure, the guide plate and the collector, the discharge trough, the guide plate and the case have sufficient strength to withstand the impact of foreign objects on the digging device.

If a steel ball projectile is used, the injection point shall be set at 12 o'clock and positioned on the top circle of the ejection device as shown in Figures AA.2 and AA.3, and positioned horizontally. For multiple ejection devices, one injection point shall be set for each ejection device. The outlet of the ejection tube shall be located so that it is flush with the upper surface of the fiber surface layer of the shell (see Appendix BB, 3B.1). The system shall be configured so that the steel ball can be ejected at a constant speed. If necessary, the machine may be secured at the bottom of the machine to prevent horizontal movement. During the test, the machine shall be operated at the maximum operating speed of the motor (specified in 2,117). For parts that are not allowed to run frequently or frequently, the machine shall be tested in various working modes. Note: The test personnel shall enter the test area with a small amount of effort and stand at a high altitude. The shovel and drag device shall be adjusted to: when it is on a hard horizontal surface, it can just touch the ground and sweep. Before the test, adjust the ball spraying capacity according to the pressure of the ball on the top of the well. The ball is placed on the top of the well with a lead weight line: 0\ The range is less than 100 meters. After understanding the situation of its position, one copper ball is shot into the machine at a time, and the steel ball is added in small increments until each ball part of the machine is passed. The test is started after it is determined that the product has been lowered. The calcium ball that is cracked or damaged shall be replaced.
During each test, 50 pellets are shot into the target area. For multi-shot equipment, each axis should be tested and the results of each test should be calculated. If during any test there is excessive deviation in a local section, it may be necessary to replace or repair the plate before continuing the test. If the hole left by the previous test cannot be covered by a 40m square label, the plate should be replaced. On any part, do not put on the glue mark completely. Before the test, the steel ball (on the test surface) can be removed by the test personnel to minimize rebound. If necessary, the European and African excavated disk wood medical projectile will be damaged by the impact. Otherwise, the test quality will be unsatisfactory. The number of hits shall be counted and recorded on the data sheet shown in Appendix C. Projectiles hitting the damage climbing area and the distance line shall be recorded as the target area below this line.
For the shovel width 6Um and above, each weapon test <5 (core required projectiles) should hit the target area from 450m to the target area without missing the target. The projectiles above the board (upper vertical x) should not hit the target. When controlling the target area forward from the 450mm line, the hit should not be more than 2 meters. For the case where the width of the shovel joint is greater than 600m, the number of bullets hitting the conveying surface to the load plate (lower and vertical area) in each test (50 bullets) should be no less than 50, of which no more than 6 bullets are hit in the plate above 3m (vertical area). In addition, the bullets hitting the working area between the bottom surface and 1mm above the 1m line (vertical area) should not exceed 2 bullets in a test failure. It can be seen that the test is carried out with all tools, and both devices must pass the test. 20.103.3 The shovel and digging device of the control device, the discharge structure, the guide plate and the collector, the discharge trough, the guide plate and the case have sufficient strength to withstand the impact of foreign objects on the digging device. After passing the flying object test: the machine is inspected again, and the shovel and digging device should not show any damage or meat 20.104 Requirements for other soil scarifiers and sand scarifiers 20.104.1—Shielding structures—Guards and shields 20.104.1.1 The excavator shall be protected by shields at the front and rear of the excavator and behind the lower support. The excavator shall not be able to approach any part of the excavator within the scope of the specification (Figure 1u7). 20.104.1.2 The surface of the excavator shall be covered by a baffle extending at least as shown in Figure 109. 20.104.1.3 The excavator end of the excavator shall be covered by a baffle extending above the upper surface. The baffle shall be extended to at least half of the surface. After the excavator is removed, the baffle shall be at least halfway above the horizontal surface of the excavator (Figure 10).2 Hazards of flying objects
In the expected period of use, the equipment should provide adequate protection to prevent the risk of injury to people caused by the falling of rotating light foreign objects. Test:
The following test should be carried out for inspection.
Place the device in the test pressure room specified by the AA. The pressure should be increased as described. The structure used shall be checked by the tests contained in Appendix AA.2 which shall be carried out before and after this test. It shall be divided into sections with horizontal lines as shown in Figure AA.1 and in Appendix CC. The projectile used in the test shall be of diameter .5 and a steel ball with a hardness of at least 4 HR. If a steel ball projectile is used, the injection point shall be set at 12 o'clock and positioned on the top circle of the ejection device as shown in Figures AA.2 and AA.3, and positioned horizontally. For multiple ejection devices, one injection point shall be set for each ejection device.
