Dear Mrs Sylvia,

We are Carpet manufacturesa company from Portugal .

We bought a testing machine for abrasion "Wira Carpet Abrasion Machine" MOd. 244 directly to SDL some years ago. With the machine was provided a test method which is Test method 20: 1971.

Until now we are making the tests acoording this method however we detected that this method had some changes. After a search we thought that the new method is PD6527 method 17 or BS EN 1813.

Could you please  confirm if that methods are correct and if they are send a copy of the new instruction manual, with the correct methods?

Many thanks for your help,

Goreti Certal
