Proposal to introduce provisions for the use of plastic safety glazing in side windows behind the B pillar more in line with the stipulations for glazing with a light transmittance below 70 per cent in that area.

Excerpt from the March 2014 session of the World Forum where Korea explained its investigation into the shattering of certain panoramic sunroofs.

CLEPA comments on the OICA proposal for Supplement 3 to the 01 series of amendments to Regulation No. 43 (document GRSG/2014/14) that seeks to avoid imposing administrative burdens on small glazing that is not required for the driver’s forward or rearward field of vision.

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.

Proposal by the IGPG working group to introduce provisions for plastic glazing for windscreens and laminated plastic panes other than windscreens into UN Regulation No. 43, superseding document GRSG-104-43.

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.

This proposal corrects an editorial mistake in the tolerances of Annex 6. In Annex 10, paragraph 3.2.2.2. and in Annex 12, paragraph 3.2.2., the correct tolerance should read: 1.5m +0/-5mm. (The same tolerances also appear in UN GTR No. 6, paragraphs 5.4.3. and 6.5.4.2.)

Text prepared to introduce provision to address difficulties encountered by technical services located at high altitudes in fulfilling the barometric pressure conditions required for the impact test. This document supersedes informal document GRSG-105-24.

Proposal to clarify the testing method for resistance to high temperature in order to address issues raised with testing at high altitudes. CLEPA proposes to amend the wording of paragraph 5.1. to clarify how to proceed with a test in boiling water, which is permitted for safety glazing with both external surfaces of inorganic material. The tolerance of +0 °C / -2 °C is taken from ISO 3917, high temperature test. The temperature of boiling water can be determined with the required accuracy easily.

Proposal to avoid imposing administrative burdens on small glazing that is not required for the driver’s forward or rearward field of vision.

Text prepared by the Informal Group on the Introduction of Plastic Glazing for windscreens and laminated plastic panes other than windscreens into UN Regulation No. 43 (IGPG) in order to clarify the requirements of Annex 21 (provisions on the installation of safety glazing on vehicles).
