48. The expert from the Russian Federation introduced GRSP-51-29-Rev.1, proposing that the former scope of the UN Regulation be applicable to all N vehicle categories. He explained the current text exempted all vehicles not having a separate cab from the loading compartment (van type). The expert from Sweden argued that the tests of the 03 series of amendments to the UN Regulation, had been designed by the informal working group on truck cab strength for vehicles heavier than 7.5 tons. He indicated that the extension of the scope, as proposed by the expert from the Russian Federation, could be a second phase of work of the informal working group. The expert from OICA, former secretary of the informal working group, reminded GRSP that his group decided specifically to increase the severity of the tests focusing only on vehicles with a separate driver’s cab. GRSP agreed to resume consideration of this agenda item at its December 2012 session and requested the secretariat to distribute GRSP-51-29-Rev.1 with an official symbol.
