Proposal for an amendment to provide for the optional use of laminated-glass panes meeting mechanical strength requirements in front, exterior, forward-facing glazing of upper deck of double decked buses instead of laminated windscreen.

Proposal for an amendment to provide for the optional use of laminated-glass panes meeting mechanical strength requirements in front, exterior, forward-facing glazing of upper deck of double decked buses instead of laminated windscreen. This is in line with similar proposal discussed in 114th session of GRSG for UN Regulation No. 43.

The objective of this proposal is to develop, in the framework of the 1998 Agreement, an amendment to UN Global Technical Regulation (UN GTR) No. 6 on Safety Glazing to adapt the Regulation to technical progress by providing optional use of thinner laminated-glass panes meeting mechanical strength requirements in front, exterior, forward-facing glazing of upper deck of double decked buses instead of laminated windscreen.

Proposal to enable the approval of the laminated-glass panes with improved mechanical properties, especially as designed for front, exterior, forward-facing glazing of the upper deck of a double-deck vehicle. This request follows the approval by GRSG of a similar amendment to UN R43 (document GRSG/2018/7) and therefore seeks to maintain the alignment between GTR 6 and UN R43.

Proposal to amend GRSG/2018/7 by adding the marking “/D” to signify laminated-glass panes subjected to the 2,260 g ball test and the headform test.

Proposal for minimum amendments to GTR No. 6 pending conclusion of NHTSA research and for further amendment concerning ceramic printer areas and sunroof safety testing.

Examples gathered by KATRI showing reductions in the ceramic printing area of sunroofs on individual vehicle models between 2015 and 2017.

Proposal to correct the scope of the GTR to align with Part A of the GTR, UN R43, and regional/national interpretations and to align the impact test procedure description with that of UN R43 and ISO 3537. The scope is amended to add “panes or as partitioning” while deleting the wording “use of double windows panes, each pane is considered a separate item of glazing panes”. The impact test procedure is clarified to define the point of impact with reference to the test piece (not the current “supported area”) and within 25 mm of its geometric centre and 50 mm of its centre.

Version 2

Explanatory statement on CPA limitation from Korea.

The US safety agency raises questions concerning the specific nature of the observed failures and the scope of the test procedures to ensure that glazing with ceramic printed areas resist such failures. NHTSA notes anomalies in the data that might suggest failure modes specific to particular manufacturers and/or production batches while questioning the focus on panoramic sunroofs rather than all glazing where ceramic printing might be a potential cause of failure.

Request for authorization to develop an amendment to GTR No. 6 (and thus UN Regulation No. 43) to establish test procedures and performance requirements for panoramic sunroof glazing.

Pursuant to its defect investigations concerning the shattering of certain panoramic sunroofs, Korea proposes the establishment of an informal working group to prepare amendments to UN Regulation No. 43 and GTR No. 6 to specify test methods for evaluating panoramic sunroof glazing.

The main objective of this proposal is to develop an amendment to UN GTR No. 6 on Safety Glazing concerning clarification of the methods (e.g. 227g ball drop test), etc. for testing and evaluating the mechanical strength of toughened glass so that the safety of a panoramic sunroof is assured.

OICA and CLEPA comments on the Korean proposal to amend GTR No. 6 and UN Regulation No. 43 in response to issues identified in its defect investigation concerning panoramic sunroofs.

Correction to clarify that the scope of the GTR covers windscreens and panes for cars and trucks and to harmonize the text with ISO 3537/ UN R43. The present text could be read to limit the scope of windscreens and double window panes.

Presentation on Korean investigations that identify certain conditions under which ceramic printing (black enamel) weakens toughened glass such that the glass no longer meets the mechanical strength requirements of GTR 6, UN R43 or FMVSS 205. Korea proposes amending the UN glazing regulations.

Proposal to amend the methodology of the 227g ball drop test for toughened glass in order to assess its mechanical strength (resistance against outside impact). This proposal stems from Korean testing that demonstrated inadequate mechanical strength of toughened glass treated with ceramic printing.
