Quality and safety

Sundisc Abrasives works according to European standards to guarantee products of top quality.

Quality is paramount

oSa – Organization for the Safety of Abrasives

It goes without saying that Sundisc Abrasives takes the safety of its products very seriously.

Formerly, there was no worldwide regulation concerning the safety of coated and bonded abrasive materials. In order to fill this gap, a few manufacturers established the oSa in 2000. The members of this organisation defined a series of safety requirements to be upheld in production processes.

In order to become a member of the oSa, all established procedures and requirements must be complied with, and audits carried out to full satisfaction.

 We are proud to be able to call ourselves a member of the oSa. This means that Sundisc Abrasives may also use the oSa logo on its products. This guarantees our clients that our flap discs meet the strictest safety norms.

Testing facilities


The minimum rotation speeds that a flap disc can bear is one of the most important elements of the strict requirements of the European norm EN 13743, which is mandatory for oSa members.  Sundisc Abrasives has its own speed testers to test this.

 Step by step, the speed tester increases the rotation speed of the flap disc being tested.  This must be at least 140 m/s according to the norm EN 13743. We run this test on 1% of our produced flap discs. On request, we add these test reports to the orders of our larger clients as an extra service.

Grinding robot

We are often asked how our flap discs perform when compared with other flap discs on the market. Therefore, together with the supplier of our machines, we developed a grinding robot specifically for testing flap discs.

This robot was developed to imitate the way a human grinds material as much as possible. The pressure is constant, but with tilting and various grinding lengths. This creates a test situation in which a human is perfectly copied, but the circumstances are always the same.

As Sundisc Abrasives offers just about all possible qualities of abrasive cloth, we now have a very complete database with test results of the different types. The tests were carried out on standard steel, stainless steel and aluminium.

 We not only use our state-of-the-art robot for our own use, but also let our clients benefit from the opportunities this robot offers. Our clients can also show these test results to their customers as a marketing and sales instrument.
