UN R149: Proposal for a Supplement to the original text and 01 series of amendments

Proposal to correct inconsistencies and calculation errors in Conformity of Production (CoP) tables across both series of UN R149, which may otherwise cause confusion for manufacturers and technical services.

In UN R149-00, corrections include: deletion of erroneous maximum values at point 50L in CoP tables for Classes C, V and W Bend Light; correction of miscalculated 20% and 30% CoP minimum values for Classes C and V Bend Light Category 1; correction of the Class W non-bending mode maximum value at Segment 10 and its derived CoP values; and correction of rounding errors in Class R CoP minimum values.

In UN R149-01, corrections include: updating the Class W Bend Light CoP maximum at point BR to align with the type-approval table; correcting miscalculated Class R Bend Lighting CoP values; and fixing table note references in Annex 4 following the introduction of scientific notation in the 01 series.

Further details can be found in informal document GRE-94-10.
