Standard Test Methods for
Evaluating the Relative Lightfastness and Weatherability of
Printed Matter1

This standard is issued under the fixed designation D 3424; 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 last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 These test methods cover the determination of the
relative lightfastness and weatherability of printed matter under
the following seven conditions, of which two involve exposure
to natural daylight and five involve accelerated procedures in
the laboratory:

1.1.1 Test Method 1—Daylight behind window glass,

1.1.2 Test Method 2—Outdoor weathering,

1.1.3 Test Method 3—Xenon-arc apparatus with window
glass filters to simulate daylight behind window glass,

1.1.4 Test Method 4—Xenon-arc apparatus with water spray
and daylight filters to simulate outdoor weathering,

1.1.5 Test Method 5—Enclosed carbon-arc apparatus without water spray,

1.1.6 Test Method 6—Enclosed carbon-arc apparatus with
water spray, and

1.1.7 Test Method 7—Fluorescent lamp apparatus to simulate indoor fluorescent lighting in combination with window filtered daylight.

1.2 These test methods require that a suitable print or other
control (reference standard) be run along with the test sample.
Colour changes due to conditions of exposure may be evaluated
by visual examination or instrumental measurement.

1.3 These test methods are applicable to prints on any flat
a substrate including paper, paperboard, metallic foil, metal
plate, and plastic film, and are produced by any printing
process including letterpress, offset lithography, flexography,
gravure, and silkscreen.

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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard
statements, see Section 8.
