Working Party on General Safety | Session 104 | 15-19 Apr 2013

35. On behalf of the task force on Liquefied Natural Gas vehicles (LNG), the expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2013/7 proposing to insert into UN Regulation No. 110 new provisions for vehicles using LNG in their propulsion systems. He also presented GRSG-104-34, GRSG-104-35, GRSG-104-36, GRSG-104-37 and GRSG-104-38 proposing further improvements to the text as agreed by the task force during its meeting on 15 April 2013, prior to the GRSG session. GRSG noted GRSG-104-32 justifying the need for such amendments as well as GRSG-104-33 listing a number of questions and answers on general LNG background issues.

36. GRSG acknowledged the work done by the LNG task force and considered ECE/TRANS/WP.29/GRSG/2013/7 in detail. GRSG adopted the document, as reproduced in GRSG-104-44, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2013 sessions as draft Supplement 1 to the 01 series of amendments to UN Regulation No. 110, subject to a final review of GRSG-104-44 by the Working Party on Pollution and Energy (GRPE) at its forthcoming session in June 2013, particularly on environmental issues.

37. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2013/10 proposing to introduce into UN Regulation No. 110 type approval provisions for electronic control units (ECUs). GRSG adopted the document, as amended, and agreed to reflect the adopted text in GRSG-104-44, mentioned above.

38. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/11 proposing to introduce into UN Regulation No. 110 type approval provisions for fuel selection systems. GRSG noted a number of concerns and preferred to refer the proposal to the informal group on Gaseous Fuelled Vehicles (GFV) for detailed consideration at the forthcoming session in Brussels. GRSG agreed to resume consideration on this subject at its next session on the basis of a revised document by CLEPA.

39. The expert from CLEPA also proposed to introduce type approval provisions for “valve control at the stop-start function” into UN Regulation No. 110 (ECE/TRANS/WP.29/GRSG/2013/12). The expert from OICA presented GRSG-104-19 improving the proposed text. GRSG agreed in principle on the both proposals, but preferred again to refer the proposal to GFV for detailed review. GRSG agreed to resume consideration on this subject at its next session on the basis of a revised document by CLEPA.

32. The expert from Germany presented ECE/TRANS/WP.29/GRSG/2013/6 superseding ECE/TRANS/WP.29/GRSG/2012/18 and clarifying the provisions of UN Regulation No. 67 with respect to hose assemblies. GRSG adopted the document, as amended below, and requested the secretariat to submit the amendments to WP.29 and AC.1 for consideration at their November 2013 sessions as draft Supplement 13 to the 01 series of amendments to UN Regulation No. 67.

Paragraph 2.7.1., the text in square brackets, amend to read (removing the square brackets):
“The assembly instruction shall be written in the language of the country to which the type of hose or couplings will be delivered, or at least in English. It shall include detailed characteristics of equipment used for the assembly operation.”

33. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2013/10 proposing to introduce into UN Regulation No. 67 type approval provisions for electronic control units (ECUs). GRSG adopted the document, not amended, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2013 sessions as part (see para. 32 above) of draft Supplement 13 to the 01 series of amendments to UN Regulation No. 67.

34. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/11, ECE/TRANS/WP.29/GRSG/2013/12 and GRSG-104-18 proposing to introduce into UN Regulation No. 67 type approval provisions for fuel selection systems respectively for “valve control at the stop-start function”. Recalling the discussion on the same subject under agenda item 8 on UN Regulation No. 110 (see paras. 38 and 39 below), GRSG agreed to resume consideration on this matter at its next session. In this respect, the Chair invited the expert from CLEPA to prepare, if necessary, updated proposals.

Referring to ECE/TRANS/WP.29/2013/101, the expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2013/28 clarifying the type approval provisions for vehicles equipped with Liquefied Natural Gas (LNG) propulsion systems. GRSG noted a list of editorial corrections (GRSG-105-02) to be inserted into ECE/TRANS/WP.29/2013/101. GRSG adopted the proposed amendments as reproduced in WP.29-161-05 and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2013 sessions as a Corrigendum to ECE/TRANS/WP.29/2013/101 (draft Supplement 1 to the 01 series of amendments to UN Regulation No. 110).
