GB/T 30464-2013Tractors and machinery for agriculture and forestry -- Installation of lighting, light signalling and marking devices for travel on public roadways (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard uses redrafted Law Amendment uses ISO 16154:2005 "Tractors and machinery for agriculture and forestry road lighting, light signals and identification device installation regulations. " this standard and ISO 16154:2005 technical differences and for the following reasons.

--- On normative references, this standard has been adjusted technical differences, in order to adapt our technical conditions, the adjusted situation Focus is reflected in the status of Chapter 2, "Normative references", the specific adjustments are as follows.

- refers to the standard ISO 303 to adjust to China's GB/T 19365 and GB 4785;

- increase cited GB/T 20949-2007.

--- Remove the original International Standard Appendix F;

--- Modify the installation requirements in Appendix E content;

--- Increased A.24 requirements.

This standard made the following editorial changes.

--- Deleted the reference to international standards.

The standard proposed by China Machinery Industry Federation.

This standard by the National Standardization Technical Committee (SAC/TC201) Agricultural machinery centralized.

This standard was drafted. Chinese Academy of Agricultural Mechanization Sciences, Luoyang Tractor Research Institute, Zhejiang Liulin Machinery Co., Ltd.

1 Scope

This standard specifies the agricultural and forestry tractors, self-propelled machinery, agricultural trailers and towed machinery road illumination, light signals and standard Characteristics and installation requirements blogs device.

This standard applies to agricultural and forestry tractors, self-propelled machinery, agricultural trailers and towed machinery.

This standard does not apply to GB/T 19365 defined special forestry machinery as well as cars, trucks, buses and other motor vehicles and trailer.

3 Terms and Definitions

And the following terms and definitions defined in GB 4785 apply to this document.

Geometric visibility anglesofgeometricvisibility Depending on the lamp visible on the surface of the minimum solid angle.

Note 1. The solid angle is determined by several parts of the ball, the reference center of the sphere is located in the center lamps equator and parallel to the ground. Determine relevant portion of the reference axis.

Horizontal angle beta represents longitude, latitude indicates the vertical angle alpha. When viewed from infinity to observe, within the range of geometric visibility, there should be no obstruction of view Obstacle light propagation of surface fat.

Note 2. If the lamp near the measurement, the viewing direction must be moved in parallel to obtain the same accuracy.

Note 3. If there is an obstacle when the lamps have been type tested in the geometry within the visible obstacle degree can not be considered.

Note 4. When the installation of lighting, if some part of its apparent surface of any part of the vehicle by means of shielding, should provide proof lamps are unobstructed still the light distribution to meet the optical element values \u200b\u200bfor the certification (see Appendix C). Geometric visibility when the vertical angle below the horizontal may be reduced to 5 ° (lamp off the ground when the height is less than 750mm), the installation of optical components measuring the light distribution area can be reduced below the level of 5 °.

The reference axis Specified by the manufacturer, when measured with light and lighting installation, as a reference direction angle field of view (H = 0 °, V = 0 °), see Appendix D.

Reference center centreofreference by the intersection of the reference axis with the external surface of the transparent factory determined in Appendix D.
