ISO International Standard

ISO 15636:2003 specifies the design and dimensions of back-up pads intended for the fixing or clamping of vulcanized fibre discs in accordance with ISO 16057, or comparable grinding tools on hand-held grinding machines, e.g. angle grinders.

The connecting dimensions of support discs and clamping units are matched for spindle ends with the common practice of this kind of hand-held machine.
