GOST R58583-2019

For the attention of users of abrasive tools. We inform you that from 01.01.2021 GOST R 58583-2019 "CIRCUITS ABRASIVE. Permissible imbalance. Methods of determination and control." (ISO 6103: 2014, NEQ). GOST R 58583-2019 does not regulate imbalance classes. All values ​​of the permissible unbalanced masses of abrasive wheels on bakelite (B, BF, B4), ceramic (V) bonds with an outer diameter D of not less than 125 mm, the maximum operating speed Vs of not less than 16 m / s can be determined from table No. 2 (in the text of GOST R 58583-2019). GOST 3060-86 "GRINDING WHEELS. PERMISSIBLE UNBALANCED MASSES AND THE METHOD OF THEIR MEASUREMENT" is no longer valid. In this regard, the class of imbalance is excluded from the marking of the circle, packaging and accompanying documents.

At the request of consumers, it is possible to manufacture circles with higher requirements for the value of permissible unbalanced masses. A tool with these requirements will be marked with the number 1.
