GRB | Session 62 | 1-3 Sep 2015

15. The expert from IMMA proposed collective amendments to Regulations Nos. 9, 41, 63 and 92 to clarify that the provisions on fibrous materials are only applicable if such materials are in contact with exhaust gases (GRB-62-06-Rev.1). Following comments by the experts from Germany and OICA, GRB invited IMMA to revise the proposal and re-submit it to the next session, possibly as an official document.
