Scope
GB/T 19123-2015 is the English-translated version of 三轮汽车和低速货车 转向信号灯配光性能.
GB/T 19123-2015 sets the photometric characteristics of the turn signal lamps fitted to tri-wheel vehicles and low-speed goods vehicles.
Clause 1 states that the standard specifies the technical requirements, test methods and inspection rules for the turn signal lamps of three-wheeled vehicles and low-speed vehicles, and that it applies to all types of turn signal lamp used on those vehicles.
The draft shows clause 1 Scope, clause 2 Normative references and clause 3 Terms, definitions and classification, split into 3.1 Terms and definitions and 3.2 Classification, and it breaks off after 3.2.
Clause 3.2 classifies the devices by their mounting position on the vehicle, their function and the minimum angle of light distribution: class 1 for a front device whose mounting distance from the nearest front fog lamp or turn signal lamp is not less than 40 mm, class 1a for more than 20 mm and less than 40 mm, class 1b for less than 20 mm, class 2a for a rear device with one luminous intensity level, class 2b for a rear device with two luminous intensity levels, and classes 5 and 6 for the side turn signal lamps used where class 1, 1a, 1b, 2a or 2b devices are fitted.
Clause 3.1.1 defines a combinable single lamp as one that can be used as a single lamp and can also be combined into a single dual lamp. Clause 2 cites GB/T 15766.1, GB/T 19119 and GB/T 19124.
The foreword records that against the 2003 edition the title was changed, the farm vehicle terms the 2003 edition used were renamed, the normative references were adjusted and reconfirmed, requirements on the angular range of minimum luminous intensity for class 5 devices were added, photometric requirements for the turn signal lamps of single-cylinder three-wheeled vehicles and low-speed trucks were added, those for multi-cylinder low-speed vehicles were adjusted, photometric measurement requirements were added for turn signal lamps installed no higher than 750 mm, and test equipment requirements were added; it also records that the standard was proposed by the China Machinery Industry Federation and is administered by SAC/TC234.
It replaces GB/T 19123-2003, was issued on 15 May 2015 and has applied since 1 October 2015.

Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 19123-2003 "farm vehicles turn signal light performance." This standard and GB/T 19123-2003. The main changes compared are as follows.
--- Standard name from "farm vehicles turn signal light performance" to "three-wheeled vehicles and low-speed vehicles turn signals Photometric characteristics ";
--- The "Farm Transporter" was renamed "low-speed vehicles," "three farm vehicles" was renamed "three cars", "four-wheel farm vehicles" Renamed as "low-speed vehicles";
--- Normative references have been adjusted and reconfirmation;
--- Increased 5 class means the minimum luminous intensity angular range of requirements;
--- Increased three-wheeled vehicles and low-speed single-cylinder truck turn signal light performance;
--- Adjust the multi-cylinder low-speed vehicle turn signal light performance;
--- Increasing the turn signal lamp installation height of not more than 750mm of photometric measurement requirements;
--- Increased test equipment requirements.
The standard proposed by China Machinery Industry Federation.
The low standard by the National Automotive Standardization Technical Committee (SAC/TC234) centralized.
1 Scope
