Marked up revision of RE3-Rev.5

Proposal to allow for the approval of systems using non-seamless double and single wall tubes subject to testing for high pressure and high resistance to pressure pulses. The proposal would also add general test requirements for LPG fuel lines and couplings based on ISO Standard 15500 for compressed natural gas equipment.

In GRSG/2017/10, Poland proposes requirements for the LPG tank and its accessories. AEGPL notes that UN R67 requires a specific bonfire test of the container equipped with specific configurations of accessories which includes markings to indicate the extension number of each accessory corresponding to each configuration. In order to ensure that the user knows whether an accessory can be fitted with a specific container, AEGPL proposes to require marking the extension number on the accessories relevant to the bonfire test (multivalve, pressure relief valve and pressure relief device) in order to prevent/forbid the fitting of any accessory not approved for use in each container configuration. This alternative proposal to that in GRSG/2017/10 would imply a new marking requirement for accessories, but would avoid the proliferation of accessory type-approval numbers and increase in paperwork.

Proposal to introduce tolerances for dish, bayonet, and acme filling units in order to reduce risks of misuse in connecting these filling units with nozzles.

Proposal to introduce a maximum service life requirement of 15 years and for the location of the filling unit of the LPG tank on vehicles.

Proposal to align UN R121 with the 07 series of amendments to UN Regulation No. 16:

1. the term “seat belt” is replaced by “safety belt”,
2. the symbol for safety belt, defined in item 21 of Table 1 in the Regulation, may be displayed in different colours to convey different meanings. Therefore, the existing footnote 18 has been added to item 21, and
3. this symbol may be replaced by different symbols for seats other than those of the front row. Therefore, a new footnote 22 is added to item 21.

Proposal to clarify that in the case where telltale No. 1 (Master lighting switch) and telltale No. 19 (Position, side marker, and/or end-outline marker lamps) are combined, the symbol may be shown in other colours than specified in the table of telltales in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004 (i.e., per footnote 18 to the table).

Proposal to correct the translation into Russian of Table 1 in document GRSG/2017/5.

Proposal to clarify provisions concerning protection of the fuel tank in the event of vehicle collision in connection with the proposal by France in document GRSG-112-09 to align the French translation with the English original. The intent is to clarify the prohibition against the presence of elements likely to cause damage to the installed tank in the event of a collision rather than to the installation of the tank per se.

Proposal to correct editorial errors, clarify the text, insert the proposal presented in document GRSG-111-13, and provide additional information to reflect provisions presented elsewhere in the text.

Proposal to require in the case where ogive protective covers are fitted to a cylinder that the covers be removed before conducting the impact damage (drop) test.

Proposal to correct the cross-reference in paragraph 6.3.3.2. where “the test shall satisfy the conditions laid down in paragraph 6.1.3. of this Regulation” should refer to paragraph 6.1.1.3.

Proposal to require that components connecting the pressure relief device with the gaseous phase be made of metal.

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.

Proposal to establish a requirement for easy access to the CNG container installation in order to permit visual (periodical) inspection as a means to reduce the safety risks, such as refueling explosion, due to corrosion.

Proposal as adopted (originally submitted as a proposal for Supplement 2 to the 07 series of amendments to UN Regulation No. 107) during the April 2017 GRSG session to address the concerns raised in document GRSG-111-35 through application of FprEN 16584-1:2015 and 2:2015, respectively referring to requirements for color contrast for signage and quality of audible information. The proposal also introduces provisions for passengers with limited mobility.
