This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D5417 − 16 D5417 − 21
Standard Practice for
Operation of the Vettermann Drum Tester
This standard is issued under the fixed designation D5417; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This practice describes the equipment and operation of the Vettermann drum tester for testing pile yarn floor covering to
produce changes in 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 testing
used pile yarn floor coverings.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions 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 responsibility
of the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Summary of Practice
4.1 The test specimen is mounted in the rotatable drum with the pile surface towards the center of the drum and the edges under
the retaining segments. A steel ball, with 14 rubber studs rolls randomly inside the drum on the pile surface for a specified number
of revolutions.
5. Significance and Use
5.1 This equipment may be used to bring about the changes in texture on the surface of pile floor covering caused by mechanical
action.
5.2 The acceptance criteria of this practice shall be set by mutual agreement between the purchaser and the supplier.
6. Apparatus and Material
6.1 Vettermann Drum Tester (See Fig. 1):
6.1.1 Drum, incorporating a revolution counter and four adjustable retaining segments (thickness: 0.60 6 0.03 in. (15 6 1 mm)
on each side wall of the drum. A free-running circular brush mounted in such a way that it lightly contacts the surface of specimens
and loose fibers are continuously extracted by a vacuum cleaner. A vulcanized fiber backing sheet 93.3 by 10.6 by 0.06 in. (2320
by 270 by 1.5 mm) is loosely laid inside the drum. This sheet remains permanently in the drum.
6.1.2 The Vettermann drum dimensions are as follows:
Internal diameter 28.70 ± 0.39 in. (730 ± 10 mm)
Internal depth 10.60 ± 0.20 in. (270 ± 5 mm)
Effective depth 9.40 ± 0.28 in. (240 ± 7 mm)
Thickness of curved surface 0.31 ± 0.02 in. (8 ± 0.5 mm)
Thickness of curved surface 0.31 ± 0.02 in. (8 ± 0.5 mm)
6.1.3 Driving System, with a speed of 1.65 rad/s (16 6 1 rpm) and the direction of rotation is reversed every five minutes, stopping
between reversals for approximately 1 s time intervals, with approximately one second stationary time.
6.1.4 Protective Cage, fits over the drum and must be in place prior to Vettermann drum rotation.
6.1.5 Round Steel Ball, fitted with fourteen cylindrical rubber studs located equally spaced on the ball surface. The studs are
replaceable and are screwed into flat faces on the surface of the ball. (See Fig. 2.):

D5417 − 21
FIG. 2 Round Steel Ball
Diameter of ball 4.70 ± 0.01 in. (120.0 ± 0.2 mm)
Distance between diametrically 4.60 ± 0.01 in. (118.0 ± 0.1 mm)
opposed flat stud-mounting
faces
Distance between diametrically 4.60 ± 0.01 in. (118.0 ± 0.1 mm)
opposed flat stud-mounting
faces
Mass without studs 15.0 ± 0.2 lb (6800 ± 100 g)
Mass with studs 16.8 ± 0.2 lb (7600 ± 100 g)
6.1.6 Replaceable Rubber Studs, are a composite rubber disk attached to a steel backing plate with integral mounting screw. The
dimensions are:
Diameter 1.54 ± 0.02 in. (39.0 ± 0.5 mm)
