A.	PROPOSAL

Annex 3,

Paragraph 3.1.2.4.2.1., amend to read (deleting the last two subparagraphs and the corresponding footnote 5/):

".... this down-shift may be avoided, at the manufacturer's choice, according to paragraph 3.1.2.4.2.4."

Paragraph 3.1.3., the reference to footnote 6/ and footnote 6/, renumber as footnote 5/.

* * *

B.	JUSTIFICATION

This corrigendum would align the test method of Regulation No. 51 with that of standard ISO 362:1998 (third edition, dated 15 June 1998). It would eliminate in annex 3 the repetition of provisions of new paragraph 3.1.2.4.2.4. in the text of paragraph 3.1.2.4.2.1. In practice this means deleting the text which had been re-introduced into paragraph 3.1.2.4.2.1. by Corrigendum 2 to

the 02 series of amendments to Regulation No. 51.

Note by the secretariat: The reference to annex 3 and the renumbering of footnote 6/ were not mentioned in the proposal, as received from Italy.
