Activities In The Field Of Standardization
Energy Efficient Electric Motor Driven Systems (CAISEMS)
The IEC Advisory Committee on Energy Efficiency (ACEE) TG6 launched on 20 September 2019 in Tokyo the project ‘Coordination and Alignment of IEC and ISO Standards for Energy Efficient Electric Motor Driven Systems’ (CAISEMS).
Between March and November 2020, four CAISEMS meetings were held (online). Their main task was to update a set of Background Documents and to prepare a Work Plan. The Work Plan, 2nd edition, includes concrete steps to prepare the start of an ISO & IEC Joint Working Group. Following the November 2020 CAISEMS meeting agreement preparatory work has started for the set-up of an ISO & IEC Joint Working Group, including at the outset IEC TC 2 (motors), IEC TC 22 (converters) and ISO TC 117 (fans).
