Standard Practice for
Preparation of Paint-Roller Covers for Evaluation1

This standard is issued under the fixed designation D 5069; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of the last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This practice describes the preparation or breaking-in of
paint-roller covers for evaluation.

1.2 This practice is applicable to paint-roller covers having
nap lengths up to 1⁄2 in. (13 mm).

1.3 This standard does not purport to address 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.

2. Referenced Documents

2.1 ASTM Standards:
D 3924 Specification for Standard Environment for Conditioning and Testing Paint, Varnish, Lacquer, and Related

3. Summary of Practice

3.1 Using the paint chosen for the evaluation, the paint roller cover to be tested is repeatedly and generously loaded
with paint and painted out over the same area of approximately
4 square feet (0.4 m2
) until it is saturated with paint, that is, the
paint-roller cover cannot pick up any more paint, nor apply any
more paint to the area being used for break-ins.

4. Significance and Use

4.1 Until a paint-roller cover is saturated with paint, only
part of the paint loaded onto the paint-roller cover can be
transferred to a surface being painted. The remainder of the
paint is absorbed into the fabric of the paint-roller cover. The
amount of paint absorbed by a paint-roller cover is inversely
proportional to the amount already present within the paint roller cover. By saturating the paint-roller cover before testing,
quantitative inaccuracies of the amount of paint delivered to a
surface are eliminated.
