Text prepared by the International Organization for Standardization (ISO) to update UN R41 with the latest amendment of ISO 5130:2012.

Proposal including indoor testing as an alternative to type approval tests of Annex 3 to Regulation No. 51 including ISO 362-3.

Proposal including indoor testing as an alternative to type approval tests of Annex 3 to Regulation No. 51 including ISO 362-3.

Proposal to align UN R51 with ISO 5130:2019 and thereby set requirements for the microphone position as a function of the exhaust outlet configuration.

Presentation on the status of the 2019 update to ISO 16254 (Acoustics – Measurement of sound emitted by road vehicles of category M and N at standstill and low speed operation – Engineering method). ISO 16254 specifies an engineering method for measuring the sound emitted by M and N category road vehicles at standstill and low speed operating conditions.

ISO 362-3:2022 specifies an engineering method for measuring pass-by sound level of a vehicle under controlled indoor conditions using a semi-anechoic chamber. The 2022 edition incorporates technological advancements and improves usability and accuracy of the measurement procedure. Improvements include additional microphones, tire temperature correction harmonized with UN R51.03, clarified indoor room qualification criteria, and normalized torque influence equation. Transitional provisions propose accepting ISO 362-3:2022 for all approvals from entry into force of Supplement 11, while ISO 362-3:2016 remains accepted for five years thereafter.

Proposal to align the CNG cylinder requirements in Regulation No. 110 with requirements in ISO 11439: 2013.

Detailed review of the proposed changes to UN R110.

Proposal to

1. Update the standards to note that all references to standards are always to the latest version unless stated otherwise.
2. Update Annex II with: Series of PRD/TPRD’s are not allowed
3. Update A.24 with the pressure relief device shall comply with the requirements given in annex 4A for the specific type
4. Update Annex 4A para 4 and para 7 with reference to ISO15500-13.

Presentation in support of GRSG/2017/22 (Proposal to harmonize UN R110 with standard ISO 11439:2013 on high pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles.)

Rationale for the proposal to harmonize UN R110 with ISO 11439:2013.

In the absence of complete harmonization with ISO 11439, this proposal recommends that Table 6.4 of UN R110 should be amended by the following for CNG-1 designs:

1. Delete A.17, A.25, and A.7 since they do not match the tests specified in paragraph 7.5 on Cylinder design qualification tests
2. Add A.15 and A.6 since they do match the tests specified in paragraph 7.5 on Cylinder design qualification tests
3. Add A.24 because paragraph 6.9 on Fire protection requires all PRDs on all cylinder types to comply with A.24.

Proposal to harmonize the requirements for CNG/LNG vehicles under UN R110 with those of the international standard ISO 11439:2013.
