Heguided the Meeting of Experts through the report and explained the main modifications proposed to the measurement method. The proposals to be incorporated into Regulation No. 30 (and Regulation No. 54 see para.21 below) were annexed to informal document No. 7 (TRANS/WP.29/GRB/R.140, draft Revision of the proposed Annex8 Appendix 1 to Regulation No. 30; TRANS/WP.29/GRB/R.141, draft Revision of the proposed Annex 9 Appendix 1 to Regulation No. 54). The views on the proposals of the task group expressed by a number of experts during the following discussion are recorded below.  r5 4.The Chairman pointed out that there had not yet been full agreement by the task group regarding the test vehicle requirements and the test speeds, and alternative proposals were given in informal document No. 7.  r5 5.The expert from the ETRTO informed WP.29/GRB that the European Commission proposal for an EU Directive anticipated that tyres would be marked by two approval numbers, one related to technical requirements and the other to rolling noise. He suggested that implications of this proposal should be considered in view of the decision by the Meeting of Experts to incorporate the tyre rolling noise requirements into Regulations Nos. 30 and 54.  r5p 6.Considering the proposed tyre load during the test, the expert from the ETRTO said that loading of the tyre had a limited effect on its rolling noise (about 2 dB(A) for doubling the load of car tyres, 5 dB(A) for traction tyres) and the high test load proposed (70 to 90 [80] per cent of the reference load) would be difficult to achieve particularly on M1 category test vehicles equipped with wider tyres. He proposed that the lower load limit be reduced from 70 to 50 per cent. He explained that tyre design had changed and most present tyres had square footprints which further reduced the influence of loading on the rolling noise. The request by the ETRTO to reduce the lower load limit was supported by the expert from France. The expert from OICA suggested to consider different loading for the front and rear axles, corresponding to the actual operation of vehicles.  r5! 7.The expert from the United States of America compared the advantages and disadvantages of using a motor vehicle for the coastby test with the trailer method and concluded that the latter would be more favourable, notably with respect to easy load control of the trailer.  r5% 8.Considering the test speeds, a number of experts expressed their concern with the alternative proposal to extend the test speed range to the lower speeds and questioned the significance of regression analysis for speeds above the top of the test speed range. (|,))Ԍ r5 9.The test conditions and the calculation of the test results referred to in informal document No. 7 were also discussed in detail.  r5X 10.The Chairman of the task group indicated that another meeting would probably be convened to consider the pending questions and the comments made during the current session. For preparation of this meeting written comments, including any alternative or additional proposals, were requested to be sent to the Chairman by the end of November 1997 at the latest. In view of a further development of the proposal for the test method, the Meeting of Experts agreed that, for the time being, informal document No. 7 should be retained as a working document and should not be distributed with an official symbol. The delegates were invited to retain their copies of this informal document and bring them for the resumed discussion of this matter at the next session.  r5 11.The Chairman of the task group "Test Surfaces" (TRANS/WP.29/GRB/24, para.13) presented the report of the task group on the meetings which had been held on 30 May and 12 August (informal document No. 8). The following matters were addressed:  r5 (a)the representativity of the results of measurement of tyre noise on the ISO 10844 test track with respect to rolling noise of these tyres on road surfaces types found in practice;#  r5 (b)the reproducibility of test results of tyres on ISO 10844 test tracks at different locations.#  r5P 12.With respect to the representativity, the group was of the opinion that optimization of tyre rolling noise on ISO 10844 might have a limited effect on real road noise reduction and considered two of the three suggested options as practical, i.e.  r58 (i)to proceed with introduction of the tyre rolling noise test on ISO 10844 test track;#  r5 (ii)as (i) above, however with a commitment to introduce a second test surface within a limited time span.#  r5  13.Considering reproducibility, the group concluded that the original goal of ISO 10844 to reduce the spread of noise measurements to 2 dB(A) had not been achieved and that in reality the measured total spread was 5 dB(A).  r5@ 14.With respect to the conclusions given in paragraphs 12 and 13 above, the group recommended:  r5! (i)To introduce the tyre rolling noise measurement on ISO 10844 test track;  r5`" (ii)To request a revision of ISO 10844 (improving of the specifications of the single surface or introducing a second coarser surface).# The Chairman of the task group "Test Surfaces" reported that no other meeting of the task group was necessary and that an initiative to request the revision of ISO 10844 standard would be taken by the Swedish member body at the upcoming meeting of ISO/TC43 in Japan (23 and 24 October 1997). He proposed that, with a view to improving tyre rolling noise measurement quality, this initiative should be supported by other member bodies of ISO/TC43.(|,))Ԍ r5 ԙ15.In the discussion which followed, the expert from OICA said that ISO10844 test track had been developed for Regulation No. 51 noise measurement and for a different test method, the coastby, the measurement spread might well exceed the design value of 2 dB(A).  r5 16.Regarding the intended revision of ISO 10844, the Chairman of the task group "Test Surfaces" stated that the road laying technology had improved and the specifications could now be made more accurate. He also confirmed that no technical specifications were yet available for the second test surface. For the experts interested in more details he offered to distribute upon request the complete minutes of both meetings of the task group.  r5` 17.Following the invitation by the Chairman, the expert from the ETRTO recalled that the counter proposal of his organization for a separate draft Regulation concerning tyreroad noise limitation (TRANS/WP.29/GRB/R.144) had already been presented to the Meeting of Experts during the previous session (TRANS/WP.29/GRB/24, para. 5). He confirmed that his organization continued to support the proposal and considered the noise limits based on the tyre width technically justified. The secretariat informed the Meeting of Experts that a letter supporting document TRANS/WP.29/GRB/R.144 had been received from JATMA (The Japan Automobile Tire Manufacturers Association, Inc.), stressing that it preferred "taking into account the tyre total performance, especially safety, e.g. wet traction".  r5 18.The expert from Japan presented to the Meeting of Experts comparison specifications (informal document No. 1) of the tyre rolling noise test used in the proposals discussed by WP.29/GRB, the proposal for an EU Directive and the ISO draft of the test method (ISO/CD 13325). He suggested that, in view of future harmonization, the values proposed by ISO should be adopted by the task group.  r58 19.The expert from France signalled to the Meeting of Experts the following corrigenda to document TRANS/WP.29/GRB/R.140 (informal document No. 5): Annex 8 Appendix 1, paragraph 4.2., correct the first equation to read: 1dddddddd (1) 1dddddddd (1)  #d6X@`7 @#?!2, ddddddddd -L SUB R ~ = ~ OVERLINE L ~ ~ a OVERLINE nu XL|.R)XdXLX0XadX?$++## ++!!_$ "!_ $!_ ++x++## In addition, in the French text the remaining part of this paragraph should be corrected by replacing the erroneously used symbol "v" by "" everywhere where applicable, equations including (correct is the English version of the text).  r5`" 20.The Chairman of WP.29/GRB thanked both task groups for their work and invited the delegations to transmit their additional comments and questions directly to the Chairmen of both groups. The Meeting of Experts agreed to resume the consideration of both items at the next session. 0%|,)) _"!0  r5 (b)Regulation No. 54 (Pneumatic tyres for commercial vehicles) Documentation: TRANS/WP.29/GRB/R.141; TRANS/WP.29/GRB/R.144; informal documents Nos. 1, 5, 7 and 8 of annex 1 to this report.  r5 21.In general, the matter of limitation of rolling noise of tyres for commercial vehicles was considered in conjunction with the noise limitation of tyres for light vehicles (see paragraphs 3 to 18 above).  r5 22.With respect to informal document No. 5 the Meeting of Experts noted that the corrigenda to document TRANS/WP.29/GRB/R.141 parallels that proposed by France for the light vehicle tyres (see para. 19 above): Annex 9 Appendix 1, paragraph 4.2., correct the first equation to read: 1dddddddd (1) !1dddddddd (1)  #d6X@`7 @#?A2,Mddddddddd -L SUB R ~ = ~ OVERLINE L ~ ~ a OVERLINE nu XL|.R)XdXLX0XadX?$++## ++!A_$ "A_ $A_ ++++## In addition, in the French text the remaining part of this paragraph should be corrected by replacing the erroneously used symbol "v" by "" everywhere where applicable, equations including (correct is the English version of the text).

For the record the amendments to document TRANS/WP.29/GRB/R.119/Rev.1 are noted in annex 2 to this report; also included is an amendment to the conformity of production provisions, proposed by the secretariat in line with the decision of the Working Party at its onehundredandninth session (TRANS/WP.29/504, paras. 15 and 17). Inaddition, the secretariat indicated its intention to check and correct the proposal in order to conform to Regulation No. 9, Revision 2, which was currently in printing. Note by the secretariat: No proposal was received regarding the transitional provision dates, paragraphs 10.2., 10.4., 10.5., 10.7. and 10.8. (in Rev.2 of the Regulation the transitional provisions were renumbered as paragraph11.). With respect to the possible date of entry into force of the 06 series of amendments (estimate: March 1998 + 10 months) the dates of Directive 97/24/EC may not be achievable.  r5' 25.The Meeting of Experts agreed to transmit the amended document to the Working Party and to the Administrative Committee AC.1 for consideration at0'|,))M_dA0 its eighth session (March 1998), as a proposal for the draft 06 series of amendments to Regulation No. 9.  r5  (b)Regulation No. 63 (Noise of mopeds) Documentation: TRANS/WP.29/GRB/R.121/Rev.1.  r5@ 26.Similarly as for Regulation No. 9 (see paras. 2325 above), the Meeting of Experts agreed to align document TRANS/WP.29/GRB/R.121/Rev.1 with Directive97/24/EC and transmit the amended document to the Working Party and to the Administrative Committee AC.1 for consideration at its eighth session (March1998), as a proposal for draft 01 series of amendments to Regulation No. 63. The amendments to document TRANS/WP.29/GRB/R.121/Rev.1 parallel those referred to in paragraph 24 above and are noted in annex 3 to this report.  r5H (c)Regulation No. 92 (Replacement silencing systems for motorcycles) Documentation: TRANS/WP.29/GRB/R.122/Rev.1; informal document No. 5 of annex1 to this report.  r50 27.Similarly as for Regulations Nos. 9 and 63 (see paras. 2326 above), the Meeting of Experts agreed to align document TRANS/WP.29/GRB/R.122/Rev.1 with Directive 97/24/EC and transmit the amended document to the Working Party and to the Administrative Committee AC.1 for consideration at its eighth session (March1998), as a proposal for draft Supplement 1 to Regulation No. 92. The amendments to document TRANS/WP.29/GRB/R.122/Rev.1, provided to the secretariat by the expert from Spain, are noted in annex 4 to this report and include the corrigenda by France (informal document No. 5); also recorded in annex 4 are the amendments to the conformity of production provisions, proposed by the secretariat in line with the decision of the Working Party at its onehundredandninth session (TRANS/WP.29/504, paras. 15 and 17). AMENDMENTS TO REGULATION No. 51 (Noise of M and N categories of vehicles) Documentation: TRANS/WP.29/GRB/1997/1; TRANS/WP.29/GRB/1997/3; informal documents Nos. 2 and 4 of annex 1 to this report; an informal document listed in annex 1 to this report (not numbered, not distributed, Russian only).  r5 28.Document TRANS/WP.29/GRB/1997/1 was considered and adopted by the Meeting of Experts. It was noted that the corrigenda proposed by the expert from the Russian Federation would reintroduce into Regulation No. 51 a provision (Annex 3, para. 3.1.2.4.2.1.) which had erroneously been deleted when introducing the 02 series of amendments, and necessary for testing of certain motor vehicles with automatic transmissions. The WP.29/GRB agreed to transmit the proposal to the Working Party and to the Administrative Committee AC.1 for consideration at its eighth session (March1998), as a draft Corrigendum 2 to the 02 series of amendments to Regulation No. 51.  r5' 29.The secretariat informed WP.29/GRB that a proposal had been received from the Russian Federation for a corrigenda to Revision 1 of Regulation(|,)) No.51 and the necessary steps will be taken to publish the document (as Corrigendum 1 to Regulation No. 51, Revision 1, Russian only).  r5X 30.Document TRANS/WP.29/GRB/1997/3 was also considered and adopted by the Meeting of Experts, with the exception, however, of the modification proposed for annex 3, paragraph 3.2.4., where the Meeting of Experts consented that for technical reasons the background noise separation of at least 10 dB(A) should be sufficient as a regulatory requirement. The Meeting of Experts agreed to submit the amended document to the Working Party and to the Administrative Committee AC.1 for consideration at its eighth session (March1998), as a proposal for draft Supplement 2 to the 02 series of amendments to Regulation No.51.  r5( 31.The presentation of informal document No. 2 by the expert from Japan was followed by a discussion, in which the comparison of actual urban driving patterns of vehicles with manual and automatic transmissions was appreciated. The results of this study in Japan and the conclusion that the acceleration noise test of ISO 362 was more stringent than actual driving conditions were taken as a contribution to the development of an improved test method for Regulation No. 51.  r5h 32.There was a first exchange of views on the proposal tabled by the United States of America for amending Regulation No. 51 with a view to introducing an improved test method, proposed in the draft revision of the ISO standard (ISO/DIS 362). Several amendments were recommended and noted by the expert from ISO. The secretariat was requested to distribute informal document No.4 with an official symbol for consideration by the Meeting of Experts at its twentyeighth session. PREPARATION OF THE 1997 REGIONAL CONFERENCE ON TRANSPORT AND THE ENVIRONMENT  r5 (a)Construction requirements on vehicles in international traffic  r5 33.The secretariat informed WP.29/GRB that the Preparatory Committee of the Conference (PrepCom) set a task force which met on 3 September 1997 to finalize the proposal to amend the 1971 Agreement supplementing the 1968Vienna Convention in view of introducing environmental requirements for commercial vehicles in international traffic; this proposal was then expected to be considered by the PrepCom at its seventeenth session (4 and 5September1997). Note by the secretariat: The PrepCom completed the work at its seventeenth session. After a final endorsement by PrepCom at its eighteenth session (Vienna, 11 November 1997), this proposal (ECE/RCTE/CONF./6) is expected to be endorsed by the Conference (1214 November 1997).  r5$ (b)Periodic inspection of vehicles in international operations  r5H& 34.The secretariat confirmed that a similar procedure was used by PrepCom as for the above (para. 33.) and the draft Agreement Concerning the Adoption of Uniform Conditions for Periodical Technical Inspections of Wheeled Vehicles and the Reciprocal Recognition of such Inspections (with its annexed Rule(|,)) No.1: Uniform Provisions for Periodical Technical Inspections of Wheeled Vehicles with regard to the Protection of the Environment) should be finalized at the task force meeting and considered at the seventeenth PrepCom session. Note by the secretariat: The PrepCom completed the work at its seventeenth session. After a final endorsement by PrepCom at its eighteenth session (Vienna, 11 November 1997), this Agreement (ECE/RCTE/CONF./4) is expected to be signed at the Conference (1214 November 1997) and the signatories invited to adopt Rule No.1 to be annexed to the Agreement (ECE/RCTE/CONF./5). DEFINITION OF TESTING PROVISIONS IN NOISE REGULATIONS Documentation: TRANS/WP.29/GRB/R.125/Rev.2.  r5 35.To justify the proposal, the expert from the Czech Republic presented comparisons showing differences in testing provisions in noise Regulations (particularly Nos. 9, 41, 51, and 63), also with a reference to EU Directives. A number of experts supported the idea of harmonization. It was agreed that differing interpretation procedures influence the results of measurement and compliance with limits. It was suggested that harmonization might best be achieved using a stepbystep approach. Responding to the invitation by the Chairman, the expert from the Czech Republic agreed to include in his comparison also the draft standard ISO/DIS 362 and information about national testing rules in Japan and the United States of America; the delegations agreed to provide him with the necessary information for this synopsis. EXCHANGE OF INFORMATION ON NATIONAL AND INTERNATIONAL REQUIREMENTSONNOISELEVEL Documentation: Informal documents Nos. 3 and 6 of annex 1 to this report.  r5 36.The expert from Japan informed WP.29/GRB that in order to reduce traffic noise annoyance, more stringent noise measuring requirements should be introduced in October 1999 for certain light categories of vehicles (informal document No. 3).  r5 37.The expert from the Russian Federation informed the Meeting of Experts about a drum bench method used in his country for research and development of tyres with reduced rolling noise emissions (informal document No. 6). In the discussion which followed, the expert from the ETRTO said that the drum method had recently been replaced by testing on a belt which could more accurately reproduce the actual conditions of tyre/road interaction.  r5`" 38.The expert from the Netherlands reported to the Meeting of Experts that an EU Workshop on Traffic Noise had been held in July 1997 in Munich, where he had participated in working group 2: Tyre Road Noise. He agreed to provide copies of the proceedings of the Workshop (in German) upon request, together with documents related to test track development (see para. 16 above).%|,)) OTHER BUSINESS Traffic noise modelling  r5  39.The Meeting of Experts agreed to keep this item on the agenda, awaiting new information.
