Proposal for amendments to Regulation No. 67
Document GRSG/2016/7
11 February 2016

Proposal to allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone. Currently, non-seamless double and single wall tubes are used in brake and fuel tubing applications, allowing for the use of a variety of end forms and coupling techniques. Provided the tubing can withstand the applicable tests according to Annex 15, Table 1, such configurations should be permitted under UN R67 in order to remove an unwarranted design restriction.
