Title
Standard Test Method for Resistance of Transparent Plastics to Surface Abrasion
ASTM International
Publication Date:
Mar 1, 2008
Scope:
This test method describes a procedure for estimating the
resistance of transparent plastics to one kind of surface abrasion
by measuring the change in optical properties.
Abrasive damage is visually judged and numerically quantified by
the difference in haze percentage in accordance with Test Method D
1003 between an abraded and unabraded specimen.
CS-10F wheels manufactured between October 2002 and September
2004 have been found to give different results than historical
values. Comparisons of data using these wheels should be made with
caution. Results using wheels made after September 2004 have agreed
with those obtained before October 2002.
The values stated in SI units are to be regarded as standard.
The values given in brackets are for information only.
NOTE 1—This test method is equivalent to ISO 3537 in the
measurement of resistance to abrasion in Section 7, but is not
equivalent to ISO 3537 in any other measurement or section. This
test method is not equivalent to ISO 9352, and results cannot be
directly compared between the two methods.
NOTE 2—This test method is similar to ANSI/SAE Z26.1, Test
17.
NOTE 3—Prior attempts to employ the Taber Abraser for volume
loss determinations of various plastics2 have been
unsuccessful because of excessively large coefficients of variation
attributed to the data. Insufficient agreement among the
participating laboratories has rendered the use of volume loss
procedure inadvisable as an ASTM test method.
NOTE 4—For determining the resistance to abrasion of organic
coatings by weight loss, reference is made to Test Method D 4060,
which uses more aggressive CS-10 or CS-17 abrasive wheels. It
suffers from poor reproducibility between laboratories when
numerical abrasion resistance values are used. Interlaboratory
agreement improves significantly when ranking a series of coatings
for their abrasion resistance.
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 and
health practices and determine the applicability of regulatory
limitations prior to use.
