1 Description
3M Diamond Grade Conspicuity Markings Series 983 are highly retroreflective microprismatic markings designed
to enhance the visibilities of the sides and rears of vehicles. These reflective markings consist of prismatic lenses
that are formed in a transparent, synthetic resin, and sealed and backed with a pressure sensitive adhesive and
clear polymeric liner. Diamond Grade Conspicuity Markings are highly durable, providing up to ten years of field
performance. 3M's Series 983 markings have excellent angularity which provides enhanced visibility for drivers.
For warranty and product information on specific applications, such as trucks and trailers, rail cars, school buses, or
emergency vehicles, please see the specific product bulletins. This product bulletin applies to applications other
than trucks and trailers, rail cars, school buses, or emergency vehicles.
• Combined fluorescence and retroreflection provides 24-hour visibility and detection.
• Fluorescence enhances visibility.
For details of the features and benefits of Series 983 sheeting, please refer to the 3M Transportation Safety
Division website (http://www.3M.com/roadsafety/).

3 Coefficient of Retroreflection, RA
The values in Table 3 are typical coefficients of retroreflection, expressed in candelas per lux per square meter
(cd/lux/m2). Conformance to coefficient of retroreflection requirements shall be determined instrumentally, in
accordance with ASTM E810 “Test Method of Coefficient of Retroreflection of Retroreflective Sheeting.” Per
ASTM E810, RA values obtained at 0° and 90° rotations were averaged to determine the RA values presented in
Table 3.
4 Typical Physical Characteristics
Table 4 describes the typical physical characteristics of Series 983. The information in Table 4 should be
considered typical only, and not be used for specification purposes.
5 Photometrics
5.1 Fluorescence
Fluorescent materials absorb short wavelength, invisible, incident radiation (solar energy) and re-emit it as longer
wavelength, visible light. This re-emission of visible light continues as long as exciting incident radiation is present.
This means fluorescent materials are especially effective during dawn, dusk, and overcast days. Fluorescence adds
to the daytime luminances (apparent brightnesses) of markings and enhances the visibilities of emergency vehicles
and other vehicles.
5.2 Color Test for Fluorescent Sheetings
Conformance to standard chromaticity (x, y) and luminance factor (Y) requirements shall be determined
instrumentally, in accordance with ASTM E991, on sheeting applied to smooth aluminum test panels cut from alloy
6061-T6 or 5052-H38. Chromaticity values shall be determined on a HunterLab ColorFlex 45/0
spectrophotometer. Calculations shall be performed using CIE Illuminant D65 and the 2º standard observer.

Fluorescence luminance factors (YF) differentiate fluorescent markings from ordinary (nonfluorescent) markings.
The additional daytime luminance provided by fluorescence is directly related to the increased conspicuity of
fluorescent vehicle markings under the varying daylight illumination conditions encountered in outdoor safety
marking applications. A marking’s fluorescence luminance factor, YF, provides a standardized measure of the
marking’s fluorescence.
A marking’s numerical YF value serves, under specified illumination and viewing conditions, to: 1) verify the
fluorescence of the marking (for nonfluorescent markings YF=0) and 2) quantify the fluorescent efficiency of the
marking. The magnitude of a marking’s YF can be used to assess whether the fluorescence of the marking is
sufficient for it to provide high daytime visibility performance under less than ideal conditions. Typical YF values for
983-21, fluorescent yellow, and 983-23, fluorescent yellow-green, are provided in Table 5.
6 Maintenance
6.1 Cleaning
Routine cleaning is recommended for maximum performance. The following cleaning methods are recommended:
• Clean with sponge, cloth, or soft brush using water and detergent
• Automatic truck/car wash or standard high-pressure hand spray under following conditions:
- Maximum pressure: 1200 PSI/80 bar
- Maximum water/wash solution temperature: 140° F (60° C)
- Minimum of 12 inches (30 cm) between cleaning jet(s) and marking
- Cleaning wand or jets at angle of no more than 45 degrees from perpendicular to the marking surface
- Use spray tip #1505 (15 degree spray angle, 05 capacity size)
• When using metal brighteners, follow manufacturer's recommendations for dilution. Thoroughly rinse brightener
from markings after soaking vehicle
6.2 Storage
Series 983 markings should be stored in a cool, dry area, out of direct sunlight, at a temperature of 65-75º F (18-
24º C) and a relative humidity of 30-50%. Rolls should be stored horizontally in their shipping cartons or original
packaging.
6.3 Shelf Life
Apply Series 983 markings within two years of date of manufacture.
7 Durability
Series 983 markings will provide maximum durability when:
• All 3M recommended procedures are followed and
• Markings are applied to vertical surfaces (within ± 20º of vertical orientation).
Series 983 marking durability depends on use. Failure to follow 3M-required techniques may reduce durability.

Below are some conditions and processing examples that may lead to reduced durability:
• Failure to cut markings around rivets, seams, and body panels
• Improper use of high pressure cleaning
• Contact with non-recommended chemicals or solvents
• Improper application or surface preparation
• Horizontal exposure
• Open cells along the edges of a marking may collect dirt, which will not reduce marking performance
• Damage due to external conditions may reduce adhesion and reflectivity near the damaged area
