2 ASTM Compliance
When 3M recommended settings are used, traffic colors yellow, red, blue, green, and brown printed with 3M
Piezo Inkjet Series 8900UV Inks onto 3M™ Advanced Flexible Engineer Grade Reflective Sheeting Series 7300 and
laminated with 1170 clear overlaminate, are expected to meet the daytime color, nighttime color, and daytime
luminance factor requirements stated in ASTM D4956, Tables 11, 13, and 2, respectively, and have not less than
70% of the coefficients of retroreflection (RA) stated in ASTM D4956 Table 1 (Type I).
When 3M recommended settings are used, traffic colors yellow, red, blue, green, brown, purple, and orange,
printed with 3M Piezo Inkjet Series 8900UV Inks onto 3M High Intensity Prismatic Digital Sheeting 3930DS and
laminated with 1170 clear overlaminate, are expected to meet the daytime color, nighttime color, and daytime
luminance factor requirements stated in ASTM D4956, Tables 11, 13, and 2, respectively, and have not less than
70% of the coefficients of retroreflection (RA) stated in ASTM D4956 Table 5 (Type IV).
When 3M recommended settings are used, traffic colors yellow, red, blue, green, brown, purple, and orange,
printed with Piezo Inkjet Series 8900UV Inks onto 3M Diamond Grade DG3 Prismatic Digital Sheeting 4090DS and
laminated with 1170 clear overlaminate, are expected to meet the daytime color, nighttime color, and daytime
luminance factor requirements stated in ASTM D4956, Tables 11, 13, and 2, respectively, and have not less than
70% of the RA values stated in ASTM D4956 Table 10 (Type XI).
When 3M recommended settings are used, black, printed on 3M™ Advanced Flexible Engineer Grade Reflective
Sheeting Series 7300, 3M High Intensity Prismatic Digital Sheeting Series 3930DS, or 3M Diamond Grade DG3
Prismatic Digital Sheeting Series 4000DS and laminated with 1170 clear overlaminate, will appear opaque.
3 Durability
3M reflective sheeting durability depends upon substrate selection and preparation, compliance with
recommended application procedures, geographic area, exposure conditions, and maintenance. Maximum
durabilities can be expected in applications subject to vertical exposures on stationary objects when processed
and applied to properly prepared aluminum according to 3M recommendations provided in Information Folder
1.7. The user must determine the suitability of any nonmetallic sign backing for its intended use. Applications to
unprimed, excessively rough, or non-weather-resistant surfaces and exposure to severe or unusual conditions
can shorten the lifetime of 3M sheeting. Signs in mountainous areas that are covered by snow for prolonged
periods may also have reduced durabilities. Atmospheric conditions in certain geographic areas may result in
reduced durability.
