GB 15235-2007Photometric characteristics of reversing lamps for power-driven vehicles (English PDF)

Foreword

All technical content of this Standard is compulsory.

This Standard is corresponding to the United Nations Economic Commission for

Europe ECE R23-2002, Uniform Provisions Concerning the Approval of Reversing

Lamps for Power-driven Vehicles and Their Trailers. The degree of consistency is non-

equivalent, with the major differences as follows.

-- the administrative articles are deleted;

-- the annex "Minimum requirements for conformity of production control procedures"

is deleted;

-- the annex "Minimum requirements for sampling by an inspector" is deleted;

-- the inspection rules are added.

The main specifications, including general specifications, photometric performance,

light colour and test methods, are consistent with the above-mentioned Regulation.

This Standard replaces GB 15235-1994, Photometric Characteristics of Reversing

Lamps for Motor Vehicles and Their Trailers; and compared with the previous edition,

the major changes of this Standard are as follows.

-- the standard name is changed from the previous edition Photometric

Characteristics of Reversing Lamps for Motor Vehicles and Their Trailers into the

current edition Photometric Characteristics of Reversing Lamps for Power-driven

Vehicles and Their Trailers.

-- the Normative References and Terms of Article 2 of the previous edition are

modified.

-- "Prescriptions on lamps of the same type" of Article 4 of the previous edition is

modified into "Lamps of different types" of Article 4 of this Standard.

-- "Requirements for the lamps used in reversing lamps" of Article 6 of the previous

edition is deleted, and "Requirements for the lamps used in reversing lamps" is

modified and included in 5.3 of the new edition.

-- Article 7 of the previous edition is modified, adding the content as follows.

1) In the case where the reversing lamp is intended to be installed on a vehicle

exclusively, the photometric intensity may be verified only up to an angle of 30°

inwards (the position of a photometric value of 25 cd in Figure 1);

2) In directions below the horizontal plane, the intensity of light emitted shall not

exceed 8 000 candelas below 5° D;

3) the requirements for lamps equipped with several light sources and lamps

equipped with non-replaceable light sources are added.

-- "Measurement Methods" of Article 8 and "Inspection Rules" of Article 9 of the

previous edition are modified.

-- the content concerning light source module(s) is added.

From the date of implementation of this Standard, GB 15235-1994 is abolished. The

reversing lamps of power-driven vehicles and their trailers submitted for new

application of type approval shall conform to this Standard.

The transitional requirements for the implementation of this Standard. for the reversing

lamps of power-driven lamps and their trailers which have passed the type approval

before the implementation of this Standard, a transitional period of 24 months is given.

This Standard was proposed by the National Development and Reform Commission.

This Standard shall be under the jurisdiction of the National Technical Committee of

Auto Standardization.

This Standard was drafted by Shanghai Research Institute of Auto Lamps.
