IEC 62841-3-4:2016+A1:2019 applies to transportable bench grinders that can be equipped with one or two accessories as follows:
- type 1 grinding wheels in accordance with ISO 603-4:1999 with a diameter not exceeding 310 mm and a thickness not exceeding 55 mm;
- wire brushes with a diameter not exceeding 310 mm and a thickness not exceeding 55 mm;
- polishing wheels with a diameter not exceeding 310 mm and with a peripheral speed of any accessory between 10 m/s and 50 m/s. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 36 months from the date of publication.
This publication is to be read in conjunction with IEC 62841-1:2014. The contents of the corrigendum of December 2016 have been included in this copy.
This consolidated version consists of the first edition (2016) and its amendment 1 (2019). Therefore, no need to order amendment in addition to this publication.
