19 Nov 2019 2020-02-18 14:51:15 UTC 9 00 series of amendments | Supplement 9 Based upon the adopted proposal: WP.29/2019/19

Proposal to introduce requirements and test specifications for light emitting diodes (LED) substitute light sources, including to

  1. introduce provisions for LED substitute light sources into Regulation No. 128;
  2. introduce a new category sheet PY21W/LED based on LED technology into the Consolidated Resolution (R.E.5);
  3. establish equivalence criteria as guidance for specifying sheets for LED substitute light source categories. (These guidelines are intended for publication, with the agreement of GRE, on the GRE website under “reference documents”, similar to criteria for new filament light sources for head lighting (GRE-77-04). In addition, these criteria are being prepared for insertion in publication IEC 60810.);
  4. a draft proposal to IEC concerning the cap/holder system of the LED light source category PY21W/LED, for information to GRE (GRE-80-03) only, to show the interlock feature and the differences with the cap/holder system of its counterpart filament light source category PY21W; and
  5. to allow under Annex 4, paragraph 1.2. a limited increase of luminous flux from 1 minute to 30 minutes within the given minimum and maximum requirements (to remove an unnecessary design restriction).
