Proposal to replace the term “double glazing” with “multiple glazing” and “double-glazed unit” with “multiple-glazed unit” and to amend provisions to permit approval of such components that involve assemblies of more than two window panes.

Proposal from Germany to allow type-approval of multiple-glazed (for example, double insulation) units as an assembly of more than two panes, such as used in caravans and motor homes.

Proposal to extend the mandate of the informal group from April 2013 to October 2014.

Project schedule for completion of amendments to introduce the type approval of plastic glazing into UN R43.

Request to extend the mandate of the informal group working on type approval test procedures for plastic glazed windows.

Text prepared by Germany to reintroduce 1) special type-approval tests and 2) special requirements regarding conformity of production to rigid plastic planes and rigid plastic double glazed units. Two further corrections are proposed in deleting 3) a false approval mark and 4) references to tests in the table of tests to be applied to safety glazing.

Update from the expert group developing provisions for plastic glazing under UN Regulation No. 43

Proposal to clarify the “resistance to high temperature” test procedure to account for the effect of higher altitudes (barometric pressure) on temperature calibrations (e.g., the boiling point of water).

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 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.

Text prepared by Germany on behalf of the Informal Group on Plastic Glazing (IGPG) to introduce new provisions for windscreens and for laminated plastic panes other than windscreens.

Proposal to align the requirements for plastic panes other than windscreens with the requirements of plastic pane windscreens. This includes amendments concerning rigid plastic panes, flexible plastic panes and rigid plastic multiple-glazed units. The proposed modifications to this type of glazing are in line with the requirements of Supplement 4 to the 01 series of amendment of UN Regulation No. 43.

Proposal to align the headform test with the deceleration measurement and the test of resistance to abrasion with ISO 15082:2016-11, including changes to the test details, correction of the headform calibration values, and the introduction of abrasion reference materials. The latter is combined with an abrasive-wheel qualification and a correction calculation (for plastic materials only).
