TC38-TG1 - Chemical Emissions
Scope - Programme of work - TC38
- Several teleconferences will be scheduled for TG1 and one teleconference is scheduled for TC38 during 2017.
TG1 addresses two issues with respect to the revision of ECMA-328. One issue is to align the RAL UZ-171 Options in ECMA-328 with RAL-UZ 205 which will be effective in place of RAL-UZ 171 in 2017. The other is to split ECMA-328 into two parts, a part for equipment using consumables and a part for equipment for not using consumables for better user’s friendliness. TG1 plans to prepare the draft of the next revision responding to the above two issues during March 2017. TG1 discussed a new determination method for VOC emitted from equipment using consumables for a year. The new method is to reduce the effect of various sleep modes on the calculation of VOC emission rate (EUT having varying patterns of sleep modes) and aims for a unified standard without the RAL-UZ 171 (205) options. The discussion was paused because the new method was not mature and testable enough for TG1 to focus on it, therefore, the two issues above were prioritized. It will be decided in April, 2017 whether to continue the study of the new determination method or not.
- Coordinate future revisions of ISO/IEC 28360
- Maintain liaisons to ISO/IEC JTC 1/SC 28, IEC/TC 108 and IEC TC 111
- Share and evaluate indoor air related media coverage with respect to IT/CE equipment
- Share actual findings on research in indoor air chemistry and particulate matter
- Observing actual developments in indoor air measurement technology
- Maintain close cooperation with JBMIA and BAM
ECMA-328 development history
The final draft of the 7th edition of ECMA-328, “Determination of Chemical Emission Rates from Electronic Equipment”, for alignment with ISO/IEC 28360 3rd edition was unanimously approved in the Ecma General Assembly on 9th December 2015. The draft corrigendum of ISO/IEC 28360 3rd edition which corrects figures 1 to 5 was submitted to SC 28 and unanimously approved in the ballot. With this approval, ISO/IEC 28360 3rdedition with the corrigendum and ECMA-328 7th edition are fully aligned.
Ecma submitted the 2nd edition of ECMA-328 to ISO/IEC JTC 1’s fast-track approval process. ISO and IEC approved it in March 2007 as ISO/IEC 28360 “Determination of Chemical Emission Rates from Electronic Products”.
Ecma approved the 4th edition of ECMA-328, which is fully aligned with the 1st edition of ISO/IEC 28360, in their General Assembly in December 2009.
