Green Document for WG 47 on Fires in Tumble Dryers
EMEA Product Regulatory Affairs Leader
June, 2019
IEC TC 61 - BLED

2. MEETING CALENDAR: Web-meeting held on January 17th 2019
Meeting held in Rome (IT) on 26 – 27th February 2019
Web-meeting held on May 15th 2019
Meeting TO BE held in Washington-DC (US) on 9 – 10th July 2019

3. Data Sharing: UK → Reported dryer fire incidents in UK UK LFB data
UK Manufacturer Data
IT → Reported dryer fire incidents in Italy
PL → Recalls from RAPEX
DE → Generic data related with domestic fires covering dryers in Germany
CA → Generic data of reported fire incidents in Canada
CONCLUSION:
it was agreed that there is a gap in the standard to cover addressed safety risk with the need of additional requirements/modifications regarding fire hazard on tumble dryers
4 main root causes are found

4. Root Causes & Clustering:
Capacitor: the capacitor issue is also under discussion of WG5 and TC61C. Since it is more cross-product related, if the addressed issue has been solved under WG5, it can be extended also to other categories as much as it is applicable.
PCB: this could be also considered as cross product issue, and currently under discussion of WG40.
Self combustion: spontaneous combustion due to high temperature and friction of the load inside drum
Fluff accumulation: overheating of accumulated fluff which is more related with installation and costumer behaviour

5. Next Action Items of WG47:
Capacitor:
The proposal from WG5 covering capacitors is at DC stage (61c/791/DC).The outcomes with compilation of comments of last IEC SC 61C meeting (28 – 29th of May / Vienna) will be presented in Washington meeting.
In parallel, IEC TC33 “Power capacitors and their applications” will be contacted and informed to be in line about ongoing studies under WG5 and WG47
PCB:
To wait until the stage of CDV approval to have more mature stage of proposal from WG40
In the meantime, WG40 members will inform WG47 about the status accordingly
Self combustion & Fluff accumulation:
To present some ideas for simulations (especially related with fluff) in Washington meeting by the experts
Some studies for; either containing the fluff or covering the parts to be contaminated by fluff by the experts are well appreciated in next Washington meeting
The experts are expected to present before/after data (if any) for the past activities related with new clauses that are implemented in their national standards
