Amendments This standard differs from DIN ISO 525:2000-08 as follows: a) clarification has been included in the Scope to explicitly exclude coated abrasive products; b) a not
8、e has been included in Clause 4 concerning the relationship with the ISO 603 series and the dimensional requirements given there; c) in Clause 4, Table 2, the description of some existing types of bonded abrasives products has been changed and type numbers 17, 17R, 19R, 29 and 40 have been included;
9、 d) all specific requirements on dimensions (outside diameter, thickness and bore diameter) have been deleted from Clause 5 and reference is now made to the ISO 603 series; e) in Clause 5, requirements for maximum operating speeds have been deleted; f) Clause 6 on designation has been reworded and i
10、ncluded in Clause 5; g) additional marking requirements have been included.
