Standards Development
This Technical Specification provides guidance on evaluation methods to mitigate the risks of fire that are particular to electric tumble dryers.
Where components are required to demonstrate compliance with this Technical Specification, the requirements of IEC 60335-2-11 and related standards are to be considered.
Electric tumble dryers are prone to the accumulation of lint within the electrical enclosure of the appliance. Since a tumble dryer is normally not airtight, fabric fibres can pass through small air gaps during operation. These fibres that escape the air flow path end up as accumulated lint in the bottom sections of the enclosure. Although tumble dryers are generally designed to minimize this, it is difficult to eliminate it completely.
The accumulated lint within the enclosure provides an additional fuel source that can increase the severity of hazards caused by electric component faults as well as abnormal overheating conditions. TC 61 has expressed the need to develop this Technical Specification to provide additional evaluation methods to determine the safety of electric tumble dryers with respect to the accumulation of lint within the enclosure.
