Proposal to add indoor testing, including ISO 362-3, as an alternative to the type approval tests in Annex 3. In addition, UN R51 allows the use mechanical or electronic devices to control the gear shifting and measures to avoid accelerations greater than 2.0 m/s2. However, the measures are not defined and the manufacturer or technical service is not obliged to document the methodology in the test report. This proposal introduces a table with examples for devices and measures for reference and would require documentation of methodology used.
