Proposal to establish a requirement for easy access to the LPG container installation in order to permit visual (periodical) inspection as a means to reduce the safety risks, such as refueling explosion, due to corrosion.
26. The expert from Germany proposed to also strengthen the requirements in UN Regulation No. 67 for the installation and inspection of LPG-containers and their accessories (GRSG-112-32). GRSG welcomed the proposal. The Chair invited all GRSG experts to send their comments, in due time, to the expert from Germany and proposed to resume consideration of this subject at the next session of GRSG on the basis of combined (see para. 25. above) proposal.
32. Reporting on some cases of structural failures of cylinders in his country, the expert from Italy proposed amendments to Annex 3A on the test requirements for the periodic requalification of cylinders (GRSG-112-28). The expert from Finland stated that these test requirements on periodical inspections of CNG/LNG vehicles in use were only recommendations to be taken into account during the type approval procedure of a new type of vehicle. GRSG noted that Contracting Parties were used to perform on their national level the periodical technical inspections in different ways. Referring to GRSG-112-32 presented under agenda item 7 (see para. 26 above), the expert from Germany introduced GRSG-112-33 proposing to also strengthen the requirements in UN Regulation No. 110 for the installation on vehicles of CNG-cylinders, LNG-tanks and their accessories as well as for their subsequent inspection of without the need of disassembling the containers.
33. GRSG noted general support on the proposals. The Chair invited all GRSG experts to send their comments, in due time, to the experts from Germany and Italy. GRSG agreed to resume consideration of this subject at its next session on the basis of official documents, prepared by Germany and Italy, taking into account the comments received.
