PROPOSAL FOR DRAFT AMENDMENTS TO REGULATION NO. 43, SAFETY GLAZING / TRANSMITTED BY THE EXPERTS FROM BELGIUM AND THE UNITED KINGDOM
Paragraphs 9.1.4.1. and 9.1.4.2., should be deleted: Annexes 14 and 16, Insert a new paragraph 6.1.3.3., to read: “6.1.3.3. For sun roofs, the abrasion test is not required.” Annex 21, Paragraph 3.1., amend to read: “3.1. (...) They are re-introduced as a correction TRANS/WP.29/GRSG/1999/12/Rev.1/Add.1 page 6 (ii) The text relating to the abrasion symbols has been redrafted on the basis of the one of the paragraph 5.5.5. and the reference to the relevant annex has been added. (...) (i) As wished by the Industry and the delegation of Japan, sun roofs will be exempted from abrasion testing. The argument is that no field of vision has to be ensured by means of sun roofs; therefore, it is rational to exempt them from any abrasion provisions.

PROPOSALS OF AMENDMENTS TO ANNEXES A AND B OF ADR. CHAPTER 5.3 OF ANNEX A TO ADR, SECTION 5.3.2.2 OF ADR, SPECIFICATIONS FOR THE ORANGE-COLOURED PLATES : AMENDMENT OF SUB-SECTION / SUBMITTED BY THE GOVERNMENTS OF GERMANY AND SPAIN
Ad e) Measures should be devised to prevent that the numbers on the plates are no longer legible after a short time as a result of being hit by stones, cleaning, abrasion owing to the weather and frequent changing of digits. (...) Following are some examples: - Abrasion tests are given in IMO Resolution A.658 (16) of 19 October 1989 for testing the abrasion resistance of reflective film. (...) - Some examples of methods for testing the abrasion resistance of digits are given below. Particular methods should be agreed upon that are appropriate to the practical requirements to be met by plates.

REGULATION NO. 43 - REVISION 4
Test of resistance to abrasion The purpose of this test is to determine whether the resistance of a safety glazing to abrasion exceeds a specified value. 8.1.3.2. (...) Cross cut test The purpose of this test is to examine whether any abrasive resistant coating of a rigid plastic glazing has sufficient adherence. (...) Plastic glazing materials shall be subjected to the tests listed in the following table. In the case of the abrasion test, the applicant shall have the alternative between the Taber test and the set of three tests composed of the carwash, sand drop and the wiper test.

PROPOSAL FOR DRAFT AMENDMENTS TO REGULATION NO. 22, PROTECTIVE HELMETS / TRANSMITTED BY THE EXPERT FROM GERMANY
The bar anvil should be used to assess the tangential forces and their integrals with time caused by projections on the helmet, e.g. visor fittings, screws, press studs and steps in the shell surface, etc. 7.4.2.3.1.2. The abrasive anvil is a sheet of grade 80 closed-coat aluminium oxide abrasive paper with a minimum supported length TRANS/WP.29/GRSP/1998/16 page 5 of 225 mm and is securely clamped to the base of the anvil to prevent slippage. 7.4.2.3.1.2.1. The abrasive anvil should be used to assess the tangential forces and their integrals with time caused by friction against the outer surface of the helmet. (...) When tested against the abrasive anvil, the helmet shall satisfy the following requirements: 7.4.4.2.1. the peak longitudinal force measured on the anvil shall not exceed 4,000 N, nor shall its integral with time exceed 28 Ns for any of the selected impact points.”
