41. The expert from the Netherlands presented GRSG-113-24 and GRSG-113-25 justifying the need to introduce in the Regulation new requirements for components used in LNG/CNG systems such as the “CNG accumulator” and the “CNG compressor”. GRSG noted general support on the proposals. The Chair invited all GRSG experts to send their comments, in due time, to the expert from the Netherlands. GRSG agreed to resume consideration of this subject at its next session on the basis of an official document, prepared by the Netherlands, taking into account the comments received.
