Proposal to modify the frequency of conformity of production inspections and random sampling and to prohibit the use of the DETA program Unique Identifier in place of the approval mark specified in UN R22 because the current mark provides important consumer information that would be lost through use of the UI. This latter prohibition has similarly been approved for child restraint systems (UN R44 and R129).

Consolidated update of UN R22 from the informal working group on protective helmets, including:

• Reference headforms (shape, dimensions)
• Oblique impact test method of measuring rotational acceleration
• Product of the spectral distribution of radiation of the signal light and standard illuminant D65
• High speed particle test for visors, and
• Test for photochromic, liquid crystal visors.

Proposal from GRSP to clarify the treatment of helmet accessories until specifications for the type approval of helmet accessories can be established.

Proposal to enable the type approval of helmet accessories sold as separate units.

Proposal to enable use of a rigid plastic speaker simulator in lieu of the current deformable simulator to facilitate and reduce the costs of testing.

Proposal to remove the prohibition on use the Unique Identifier per the WP.29 decision to change the default application of the UI from a requirement (requiring prohibition in cases where UI does not apply) to a permission (requiring an affirmative statement that UI may be used under a Regulation).
