approval (Article 5 of Annex I), modification of approval (Article 6 of Annex I),

product uniformity (Article 7 of Annex I), informative documents (Annex II) and

approval mark is deleted, and the reason is the differences in the forms of the

standard system and legal systems;

-- "when the vehicle is in running order with one passenger in the front row (2.1 in

Annex I of 78/549/EEC)" is changed into "when the vehicle is in running order with

two passengers in the front row (5.1 of this Standard)". The reason is that

considering the factors relating to the body weight of Chinese, the weight of

passengers is calculated in accordance with the average calculated weight 65 kg.
