Scope1.1 This practice describes the equipment and operation of the Vettermann drum tester for testing pile yarn floor covering toproduce changes in

3、appearance and color due to changes in surface structure by mechanical action.1.2 This practice is only applicable for use in testing unused pile floor covering of all types. It is not applicable for use in testingused pile yarn floor coverings.1.3 The values stated in inch-pound units are to be reg

4、arded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the

27、est in thestandard atmosphere for testing textiles. textiles as per Practice D1776.10.2 Remove the protective cage from the tester.10.3 Loosen the outside bolts.10.4 Wipe the inside of the drum and the steel ball with a clean lint free tissue and one of the recommended reagents.10.5 Inspect the rubb

28、er studs on the steel ball for signs of wear or damage and replace as needed.10.6 Fit the test specimen into the drum with the pile surface towards the center of the drum and the edges under the retainingsegments and clamp into place by tightening the bolt.10.7 Place the steel ball in the drum on th

29、e pile surface.10.8 Replace the protective cage over the Vettermann drum.10.9 Set the revolution counter to the desired number of cycles (Note 1) and switch on the machine. When the machine stops,loosen the bolts, remove the mounted specimen and place in the central aperture of the cleaning frame.10

30、.10 Using the upright vacuum cleaner, make four forward and four backward passes along the length of the mountedspecimen ensuring all the area is covered and the final pass is in the lay of the pile and condition the specimen for a minimumof 24 h.NOTE 1Common practice in the pile floor industry is t

31、he use of 22 000 cycles for commercial and 5000 cycles for residential constructions. Othercycle counts may result from mutual agreement between purchaser and supplier.D5417 16311.
