Proposal to amend the light source category LR4. This proposal relates to document GRE/2018/49 proposing to amend UN R128 in relation to the 1 min/30 min ratio. The change to UN R128 would affect the requirements of the LR4 category which is not its intention. Therefore, the present proposal modifies the category sheet of LR4 in order to maintain the current requirements for the LR4 standard light sources.
