They shall be discs of diameter about 130 mm, or squares of about 120 mm with corners to give a diagonal of about 130 mm, and have a hole of diameter 6 mm in their centres. Test specimens shall be flat. When the test specimen cannot be cut from a wash basin, specially prepared specimens can be used provided the top functional layer is of the same thickness as that in a wash basin to be tested. The thickness of the top layer shall be measured in accordance with 5.6.3. Clean the surface of the test specimens with a non-hazardous organic solvent which is immiscible with water. 5.7.4 Procedure — Prepare the abrasive wheels by bonding a strip of abrasive paper (see 5.7.2.2) to each of the rubber covered wheels, using either the adhesive backing, if present, or the double-sided adhesive tape (see 5.7.2.3), in such a way that the cylindrical surface is completely covered, but without any overlapping of the abrasive paper. — Check the suitability of the abrasive paper by preparing two abrasive wheels with unused strips of abrasive paper from the batch to be used for testing as follows: Clamp a zinc plate (see 5.7.2.1) in the test specimen holder, operate the suction device, and abrade the zinc plate for 500 revolutions. Wipe the zinc plate clean and weigh it to the nearest 1 mg. Replace the used abrasive paper strips on the wheels, with unused strips from the same batch, clamp the same zinc plate in the specimen holder, lower the abrasive wheels and operate the suction device. Abrade the zinc plate for an additional 500 revolutions, then wipe it clean and reweigh it to the nearest 1 mg. Its loss in mass shall be (130 ± 20) mg. Any batch of abrasive paper which causes a loss in mass of the zinc plate outside this permitted range shall not be used for testing. — Prepare sufficient abrasive wheels for the test, using unused abrasive paper. Fit two wheels to the machine loaded to 250 g each and set the revolution counter to zero. — Clamp the test specimen in the holder, ensuring that its surface is flat. Lower the abrasive wheels onto the test specimen so that the wheels’ cylindrical faces are at an equivalent distance from the test specimen’s axis of rotation but not tangential to it. Operate the suction device and allow the test specimen to rotate. — Replace the abrasive paper after every 100 revolutions. — Stop the test after 750 revolutions.
