IEC Foreword
1) IEC (International Electrotechnical Commission) is a global standardization organization composed of national electrotechnical committees. The purpose of IEC is to promote standardization in the electronic and electrical fields. all possibilities for international cooperation, for which, among other activities, the IEC publishes International Standards, whose preparation is credible to technical committees, any IEC National Committee interested in the subjects involved International governmental and non-governmental organizations associated with IEC can also participate in the preparatory work. IEC and the International Organization for Standardization (ISO) work closely together in accordance with the conditions determined by the agreement between the two organizations. 2) A formal decision or agreement on an IEC technical document drawn up by a technical committee in which the National Committees have a special interest in the submitted content expresses as close as possible an international consensus concerning the content. 3) They are published in the form of standards, technical reports or protocols and in the form of recommendations for international use, in the sense that they have been recognized by various national committees.
4) In order to promote international uniformity, IEC National Committees are responsible for using IEC international standards in their national and regional standards as much as possible. When there are any differences between IEC standards and corresponding national standards or regional standards, they should be Whenever possible, indicate this in national or regional standards.
5) IEC does not provide any procedures for marking approval, and IEC is not responsible for any equipment that claims to comply with an IEC standard.
This standard was developed by IEC Technical Committee 34 (Lamps and Equipment) and Subcommittee 34D (Lamps). The second edition of this standard cancels and replaces the first edition published in 1979, the first revision in 1983, and the second revision in 1987.

4) If it is intended to be installed more than 8m above the ground, it will withstand For the maximum projected area of ??the wind, see Article 6.3.1. 5) If necessary, the range of cross-sectional areas of the suspension cables suitable for the luminaire. 6 Structure
The requirements of Chapter 4 and 6.1~6.5 of GB7000.1-1996 apply. 6.1 The waterproof grade of road and street lighting fixtures should be at least IPX3. 6.2 Luminaires suspended on jumper cables should be fixed with fastening devices. The size range of the jumper cables suitable for the fastening devices should be specified in the instructions provided with the light fixtures. be explained in. The device shall clamp the jumper cable to prevent displacement of the fixture relative to the jumper cable. During the installation and normal use of the lamp, the suspension device shall not damage the jumper cable. The qualification inspection shall be carried out by visual inspection after the lamp is fastened to the thinnest and thickest jumper cable within the scope specified by the lamp manufacturer. Note: Care should be taken to avoid electrolytic corrosion between the fastening device and the jumper cable. 6.3 The luminaire should be mounted on the support in a manner appropriate to the weight of the luminaire. The connector should be designed so that there is no excessive bending when the entire projection surface of the lamp is subjected to a wind speed of 150km/h. Fasteners that bear the weight of the luminaire and its internal accessories shall be provided with measures to prevent any part of the luminaire from loosening due to vibration, either during use or during maintenance.
Lamp components, in addition to being fixed with at least two devices (such as screws or similar devices with sufficient strength), should also have additional protective measures to prevent the fasteners from being damaged under normal circumstances. These parts will not fall and endanger people, animals and the surrounding environment. Compliance is checked by visual inspection and the test of 6.3.1 is carried out for high-ceiling or straight pole-mounted lamps. Note: Considering the possible impact of vibration, the lamp, together with the light source and pole it may use, should be considered in 6.3.1 Wind test of tall or straight pole-mounted lamps. The lamp should be placed horizontally with the largest projection surface viewed from the front and in accordance with the manufacturer's instructions. Recommended fixing accessory method for installation. Use a sandbag as a constant and uniform load and apply it to the lamp for 10 minutes. The installation height of the lamp should not exceed 8m when in use. The pressure generated by the sandbag on the projection surface of the lamp should be 1.5kN/m. When the installation height is above 8m, it is 2.0 when it is below 15m. kN/m2, 2.4kN/m2 when the installation height is 15m or above. The luminaire is then rotated 180° in the vertical plane around the mounting point, and the above test is repeated. During the test, the luminaire shall not be damaged or displaced from the fixed point, and the permanent deformation produced after either of the two processes of the test shall not exceed 1°. Figure 1 gives a schematic example of this test procedure. 6.4 If the correct position of the light source cannot be guaranteed by using a simple lamp holder, an appropriate supporting device should be provided. For adjustable lampholders or optical components, appropriate reference markings should be provided. Compliance is checked visually.
6.5. The glass cover should be composed of glass that can be broken into small pieces, or have a sufficiently small mesh protection device or coated glass that can retain glass fragments.
Compliance of flat glass covers is checked visually or, if no protective device is provided, by the following test. Support the entire area of ??the glass component to ensure that when the glass breaks, the particles will not scatter and prevent the particles from moving. At the midpoint of the long side of the glass, 30mm toward the center, impact the glass with a center punch, and the glass will break within 5 minutes. , calculate the fragments within a square with a side length of 50mm approximately located in the center of the most severely shattered area. This square does not include any edges of the glass, holes or areas within 30mm of the impact.
If the number of broken particles in a square with a side length of 50mm is not less than 60, the glass is considered qualified. A suitable method for counting particles is to place a square piece of transparent material with a side length of 50 mm on top of the glass and then mark each particle within the square with an ink dot and calculate it. For the particles on the edge of a square, select any two adjacent sides of the square, count all the particles crossed by the two sides, and do not count the particles crossed by other sides,
Regarding the glass cover formed by flat glass , the test is under consideration, 7 Creepage distances and clearances

9 terminal blocks
GB7000.5—1996
Chapter 14 and 15 of GB7000.1—1996 apply. The terminal block connecting the power supply shall allow the connection of wires with a nominal cross-sectional area in accordance with Table 14.1 of Chapter 14 of GB7000.1-1996. However, power cables with a cross-sectional area less than 1mm2 are excluded.
Compliance is checked by installing conductors with the specified minimum and maximum cross-sectional areas. 10 External and internal wiring
The requirements of Chapter 5 of GB7000.1-1996 and Article 10.1 below apply. 10.1 Road and street lighting fixtures should be provided with a cable holder to eliminate the tension caused by the connection of the conductors of the power cable to the terminal block. Without the holder, the weight of the cable will create a tension at the connection point. Compliance is checked by the relevant tests in Chapter 5 of GB7000.1-1996, but the test should be conducted with a tensile force of 60N and a torque of 0.25N·m.
The values ????used for tension and torque depend on the weight of the power cable. Generally speaking, the above values ??are appropriate, but for lamps intended to be installed higher than 20m and if the weight of the power cable imposes a force on the fixture If it exceeds 4kg, the test should be carried out with a pulling force of 100N and a torque of 0.35N·m.
