Scope. This
specification covers embedded fiberglass signs. Typical applications include for warning
signs, signs for architectural directions and buried cable signs.
- Material. The sign shall be constructed from
polyester and acrylic resins that saturate a printed carrier sheet. Inks shall be screen
or laser printed onto the carrier sheet.
- Physical Properties. The sign shall have the
following characteristics:
- Specific Gravity (ASTM D105)1.30 g/cc
- Barcol Hardness (ASTM D2583)55-60 barcol units
- Flexural Strength (ASTM D790)14,000 psi
- Izod Impact Strength (ASTM D256)8 ft lb/in of notch
- Surface Energy43 dynes/cm
- Tensile Strength at Yield (ASTM D882, 638)10,000 psi
- Vicat Softening Temperature 260ºF
- UV Stability. The sign shall also be weathered
using ASTM D4329 and UVA 340 lamps. After 10,000 hours of exposure in a QUV weathering
deck the sign shall remain readable and have little fading. Sample of weathered and
printed sign shall remain on file at the manufacturer and is available for review by the

- Thickness and Dimensions. The sign shall be
0.110" thick {FQ-90 mils; FR-60 mils}. The sign shall be [___.___"] high by
[___.___"] wide.
- Corner Radius and Edge Finish. The signs shall have
[square, 1/16" radius, 1/8" corners]. The signs shall have a polished, routed

standard diamond repeat of the chain-link fence, including allowable deviations.
Typically, the centerline of the holes shall be spaced 3-1/2" apart. The fence clip
shall be fabricated from a 0.090" thick aluminum and a 1/4-20 locking PEM insert. A
[tamper-proof] bolt shall be provided for each hole.
